Thursday I spent about three hours riveting pieces together.

Saturday I spent another three hours. In the end the fuselage and all gussets are riveted aft of the baggage back. In addition I installed sound deadening material on the aft side of the baggage back, and on the top diagonal area on the side skin immediately aft of the baggage back.

It turns out that leaving the forward longerons pre-drilled at A3 is a good idea. I fit the fuselage gussets and found that I needed to drill through existing A5 holes.

The shoulder harnesses are rounded and ready to be drilled. I also have the forward fuselage channel clamped into place.

It took two hours to finish assembling the fuselage. I tried to pay attention to the route of extraction so all the clecos could be easily accessed.... but the baggage area's clecos are hard to reach.

I did a quick count and calculation. Currently there are about 446 A4 clecos being used on the fuselage right now.

In addition, all the ("L") angles that attach to the bottom skin are now riveted along with the doubler for the controls on the top skin.

Two hours were spent Sunday finishing the priming job. A while ago I ordered what I thought was the last of Wick's Zinc Chromate, but I ended up receiving the new Tempo primer that is "chromate free".

Most of the fuselage has been primed with this now. There are several issues with it. First it seems to chip off in clumps easier. Second, the initial spray is mostly propellant until a good 1/4 of the can has been used. Third the spray button is much harder to press and hurt my finger after a while. Fourth, and most importantly, the primer smeared or erased my Sharpie marks severely.

It only took about an hour Monday to get the "frame" reassembled.

I did a few steps to ease the reassembly of the fuselage. First with the ("L") angle that meets with the gussets, I scribbled the backs with different colored Sharpies so it could be easily determined where the overlaps happened and in which order.

Second, I numbered each set of of holes on the gusset so I could maintain orientation. Luckily using multiple methods worked since many times both were erased by the primer.

Wednesday I deburred and chromated for about an hour and a half.

Friday the remaining skins and angles were deburred. In addition much of the bottom skin was riveted. I decided it was best to rivet the bottom skin separately so the fuselage would not have to be rotated onto it's side. This also freed up several hundred A4 clecos. This took about two and a half hours.

One major tactic I'm using is to try to keep sub assemblies together to make reassembly easier. So far it's working.

Two hours were spent on disassembly and deburring. The top longerons, sound reduction ("L") angles, bulkheads, rear most truss, top skin, and baggage back were all processed. In addition I cut the baggage area sound deadening material.

As an experiment I took some extra 3/4" sound proofing material and roughly cut it to the size and shape of my Jeep's floor mats. I've noticed that much of the noise in my very loud Jeep seem to come up through the floor. You can feel it in your shoes. While I don't have a sound meter, this should be an interesting test... even though the frequencies will be completely different, I didn't open up the doors, or the firewall, or do the rear passenger area.

Six hours were spent changing the color of the clecos. Everything is now at least an A4, with most A5s drilled. There are still a few A5s, but finding were they should go will take the longest time.

Some of the sound proofing material was also cut.

On Friday I ordered my upholstery from Skyshops. During the two months it takes to get here, I'll just use some sofa cushions when making airplane noises. When ordering the fabric I made a color swatch and a mockup based on Brian's ( http://www.701Builder.com ) interior.

On Saturday we spent about three hours. Most of the time was spent changing the color of the clecos.

The major progress made was with the additional ("L") angle placed on the side skins. To get them on was a two person job. One person was on the inside cutting and trimming the pieces to length and buttressing the piece while it was being drilled, while another was on the outside spotting for the edge distance line, drilling and clecoing.

If I were doing this again, the simplest way would be to predrill the holes and add the angle before mating the skins together.

Because of the space restrictions, being unnecessary and better fit, I did not tie the angle into the other frame pieces.

When the forward most piece was added, there was some noise reduction when the fuselage was shaken. When the aft most piece was added there was a huge reduction. Now the only shaking noise comes from the forward pieces that have not been drilled yet.

Thursday I got in two hours of work. We got the baggage panel drilled into place, along with the uprights getting tied into the ("L") angles they are adjacent to AND I predrilled the side skins for the extra stiffeners.

Also pictured today is my fix for the overzealous trimming I performed yesterday.

With this baggage panel in place the rigidity of the whole assembly seems to have doubled.

It took two hours to do a thirty minute job.

I accidentally way over trimmed the extended baggage panel ( 7F8-9B ). And by over trim, I mean I read the plans and the the directions...

The plans simply say "trim to fit", but I forgot that the panel was supposed to overlap the Zee Channel ( 7F8-10B ), so I thought the panel was 10mm too long, which made since since the baggage back was off by 10mm.

The remedy the situation I was able to find some extra 0.025 laing around that happened to be 800mm wide. I cut a piece 60mm deep and drilled it onto the front of the panel. Problem solved.

I did have to trim the extended panel in by 5mm on each side.

That will teach me for not triple checking against the HBH videos, plans AND manual.

The only building on Saturday was that of a doughnut cutter out of scrap. The subsequent homebuilt pastries were superior to anything Dunkin or Crispy could produce.

One Sunday we spent about three hours on the fuselage. I discovered that the mounts on the horizontal stabilizer are about 10mm to far inboard on each side, so they have to be opened up again and fixed.

The uprights, ("Z") channel, baggage back, and lots of ("L") angle were all drilled into the fuselage. The whole assembly is now very stiff.

When positioning the ("Z") angle it was helpful to use some scrap as a gusset - just clamped on for the moment to keep the piece in the correct vertical placement. Also the angle had to be trimmed on the sides for it to fit correctly.

During this process a second set of hands has been required for the effort. It's really unclear to me how a person could do most of this alone.

Saturday five hours were spent. The big highlight was the mis-matched ("L") angle. I'm still trying to decide what to do about that. Besides that, the rear hole doubler was put in place, the sides and top skins were mated and the bulk heads were drilled into place on the pilot side and top.

The fuselage is squared up.

On Saturday two hours were spent once again on the CNC error, and getting the interior gussets into place. The gussets still need to be trimmed.

Also, I am considering adding some extra ("L") angle to reduce the "audio slip indicator":

Recap of the question posed to the Matronic's Zenith list:

I'm having a bit of a problem. The ("L") angle that attaches to the top of the baggage back is off by exactly 10mm. This seems strange since every other junction is dead on, and the longeron splices are exactly even between the sides and the top. The flanges for the bulkheads were dead on.

So this leads me to believe it is a CNC error, but it's a little hard to get up there to measure and prove it.

Anyway, this has produced a gap too big to shim and I'm not sure what to do about it. One thought I had was to move the angle forward, but then the existing holes would be directly over the baggage back and the vertical ("L") angles.

My other idea was to ignore the gap basically since when I test fit the baggage back only the area near the gap didn't site flush. So I would add some extra rivets towards the inside of the panel to make up for it, and maybe add two gussets. My guess is that two rivets on each side would have to be skipped.

Saturday we spent about two hours mating the passenger side skin to the bottom skin. To do this we also drilled the top side longerons to the top skin. Also the bulk heads were drilled to the passenger side.

This is all insanely cleco intensive.

Seven hours of progress were made on Sunday. The bottom skins, longerons, "L" angles, "Z" angles and bulkheads were drilled out to A4 and A5 holes. The everything was deburred and corrosion protected then reassembled.

The "L" angles for the top skin were drilled into place and trimmed, and the longerons were lined up and are ready to be drilled.

Everything was simple and straight forward, but the number of holes in the fuselage takes a hug amount of time.

We spent about three hours on Saturday night. First the upper longerons were drilled to the pilot side skin, then the bottom longerons were transfered to the side skins. After that the torque tube bearing and doubler were deburred, zinced and riveted together.

When transferring the longerons, the best thing to do is to use a helper and hold the bottom skin next the to side skin to help accurately determine the position of the longeron on the side skin. In addition, use a Sharpie to mark the edge of the skin against the longerons and the position of the bulkhead rivet lines for additional accuracy.

A fellow EAA chapter member gave me a generous ride down to Portland in his RV-7A. That is a nice flying plane. The control was so nice I believe I need to fly down to Oregon again to get a factory ride in the RV-8... because it's never too soon to think about the next project.

We spent about two hours working on the passenger side fuselage skin. A good portion of that time was spent determining which of the pre-drilled hole lines the "L" angle was to be attached to. I found that placing a piece of wood between the "L" angle and table helped keep the pieces lined up.

Besides that, the sheer number of holes for the longerons takes a while to drill.

It turns out that determining if a skin is in the radius of an "L" angle or longeron is hard. To help keep the skin out of the radius of the longeron I used a red Sharpie to draw a line down the radius of the longeron. This visually made the process much easier.

It took about 3 hours to complete section two.

A good portion of that time was spent testing the flat drill bit on scrap to make sure it would work on aluminum with a hand drill.

There were also two mysteries not solved by the plans or the HBH video. First the (Z) angle that runs alongside the access hole was about 680mm. The (L) angle perpendicular to it was about 180mm. The edges will have to be trimmed on all four pieces to an angle to match the pieces around them. Also round off the edges.

I also found that 7F6-1 ( Bottom Channel ) had the be trimmed by several millimeters on each side and the flanges trimmed to an angle to fit even though it was in the correct position.

Unclecoing the front of the bottom skin and then pulling it over works well for drilling 7F6-1 into place, but the entire assembly will have to be flipped over to install the (Z) angles and (L) angles.

It is also important to note that Zenith does not supply hardware to attach the access cover with. They do give you the option of riveting the panel to the skin.... but that's not really an option. Buy some nutplates before reaching Section Two.

The first part of Saturday was spent dealing with the empty crate. After unscrewing and prying the thing apart we got our driveway back.

In three hours the entire first section of the fuselage manual was completed. The rear bulkheads, (L) angle, (Z) angle, and longerons were all drilled into place.

Much of this quick progress is attributable to having seen the steps performed first on the Homebuilt Help videos.

Bending the fuselage skin forward to get to the bulkhead flanges is a great idea. To help with positioning the longerons, I backdrilled into the table through the bulkheads and (L) angle to allow the bottom skin to lay flat to the table while clecoed together. This technique also help keep the longerons in place while drilling and the skin from creeping into the radius of the longerons.

A lesson from having my wings inspected:

One thing to look for: With the skeleton assembly of the rear strut support, make sure that the piece of (l) angle that helps connect the trailing edge skin does not interfere with the middle line of rivets.

This is the best picture of the issue I have:



The rivets need to be drilled out and the area near the rivets needs to be filed into a a circular shape so the metal does not rub against and cut the rivets.

The other thing to look out for is the fit of the root skin. You do not want a perfect fit between the wing and root skins. They will shift and rub against each other in flight and is a potential source of cracking. Make sure you have a gap between the skins and then use sealer later.

After a big struggle with Sunshine Shipping the initial 9AM to Noon delivery window turned into 9:15PM.

Saturday morning I had my wings inspected by an A&P/701 flyer. There were a few corrections to be done, but nothing painful, tricky or too time consuming. My plan is to perform these later closer to final assembly.

Saturday evening I took inventory of the fuselage crate and found a part to be missing. Luckily it is a part used later on in the process.

I bought the Homebuilt Help 701 Fuselage DVDs and started watching the "Rear Fuselage" disc. Overall this is a big help, but it could have slightly better production values. I fully expect that just seeing the steps performed will have major time off the fuselage.

Two hours were spent on the last holes on the right wing. Many holes still need to get drilled out to A4 and A5, but the hard part is done.

For the inboard section of the wing root I made only a few holes with the strap duplicator making sure that the top skin had the crimped regions marked. Then I connected the dots and drilled the remaining holes for a better fit.

The extra 400 clecos ordered from Wicks came in handy.

On Saturday my wings will be inspected for craftsmanship, and any needed corrections will be made. After that I will do all the needed drilling out, fuel filter installation, ground wire installation, deburring and corrosion protection, final wire run and then riveting. I hope to get back 500 clecos from the wings.

Friday the fuselage arrives at some point between 9am and Noon.

We spend four hours on the right wing. The fiberglass and metal Horner tip were drilled into place along with the outboard portion of the wing root skin.

For the (L) angle that helps holds the tip, the best thing to do is to predrill the portion that contacts the spar extension, and then back drill it into place. Otherwise it would be to awkward to get the drill into that portion of the wing.

The fiberglass fit much better this time, but I had to fabricate a small extension to get the nose skin into a safe edge distance on the most rounded part of the tip.

The area of overlap between the fiberglass was much better and no extension was needed this time.

When you layout the wing root skin, do yourself a favor and actually use the corner of the metal as your ( 0, 0 ) point.

This time when doing the rough trim I was smart enough to use the Olfa knife which saved a huge amount of time.

Over the weekend only a little building got done due to camping, and then a light cold.


First last week, there was one hour of building that included drilling some holes out to A4s and getting the lower tip angle positioned, but not drilled.

The skin had a slight bubble to it that just got pushed around. The solution was to drill out the rivets holding the outer most lower skin to the trailing edge skin, drilling the lower angle into place, and then enlarging the previous holes to A5s. This did not eliminate, but drastically reduced the bubble.

Monday nights session was only two hours and included drilling the top and lower angles into place and preliminary positioning of the fiberglass tip.

It was a two hour long battle to get the fuel send perfectly seated into the tank.

Several issues to avoid
  1. Zenith shipped an extra seal, the one I used was a worse fit than the other.
  2. The ohm meter had a calibration wheel that I forgot about, and I was confused to why the readings were so strange
  3. Make sure that hole is circular! If not you may need to smooth it out to keep the bolt from using the tank as it's thread.
Most of all, enlarging the hole is a slow process. I also got the grounding setup on the tank,

Sunday we spent five hours in a building sprint. The lessons learned from the left wing allowed for rapid progress on the right wing.

The first, smaller cut for the fuel sender was made, the fuel tank channels were drilled into place, the fuel drain hole was made, and the fuel feed hole was also made.

For the fuel drain hole I attempted something different. On the left wing I measured and was off. For this wing I place the tank in the wing and felt where the drain pushed against the wing, and marked that spot.... and was off. So I measure and hit it on the spot, creating two holes. I created a patch that rested on the inside to close the hole up.

The fuel sender hole is just a rough cut and needs to be enlarged.

Luckily the fuel filler template was 100% reusable for this wing. Due to the CNC pre-drilled holes, I was able to just flip the template over. I undercut the hole intentionally and then enlarged the hole with a half round file for a near perfect fit.

For comparison the same amount of work for the left wing took about twelve hours.

We spent about three hours on the wings Saturday night. Only one hour was spent on construction. The other two hours were spent on the workshop.

First up was bending the wing root skin and drilling it. This is harder than it should be.

First I bent the trailing edge as indicated in the manual, but the skin is too stiff. I attempted using duct tape to hold the skin, but that didn't work.
After un-clecoing the skin, I made a few slight bends in the skin to make it easier to round the tip ribs. Then using an assistant, the holes were drilled.

The left wing is now ready to be inspected and prepared for final riveting!

I spent an hour bending the root skin over. This is a slow process if you want a good fit. It took lots of incremental trimming and filing.

Once a fit +/-3mm was achieved between the main top skin and the root skin, I used a rasp on the root skin to get everything flush. This worked very well.

All that is left is for the skin to have the bottom bent and drilled, then it goes on the wall waiting for inspection.

Two hours were spent fabricating tools and drilling the wing root skin into place.

The new "strap duplicator"/"hole finder" is made from two old worn out saw blades. On the free end a partially pulled rivet is trimmed so the nail is only a few mm long, and the head is then filed down to reduce parallax. The flaw with my new design is that the pointy "finder" gets drilled out after a few uses and then requires replacing.

Getting the skin drilled properly was a fairly easy task for three sides. The line that abuts the first rib, the spar doubler line, and the rear channel lines were all easy.

The pilot holes on the root rib side are off by about .25mm, so when the holes are enlarged to A4 everything should be OK.

I think a better method would be to pre-drill only a few holes, use the hole finder on those, and then extrapolate the line, pre-drilling the root skin and then back drilling into the root rib.

I spent another hour on the root wing skin... this time laying out the correct side. After giving it a rough cut and reading over the directions, I decided I need a new tool. The hole finder I fabricated is not the correct type. Mine was under the assumption that the existing hole was accessible from beneath, also it was way to short.

This wing is getting close!

Another two hours of progress...

First the wing root angle angle was crimped trimmed, drilled and placed.

Next I carefully measure the wing root skin. This took forever... only to figure out that I measure for the right wing... and I'm working on the left wing.

At least work wasn't lost.

On Monday I will measure for the left wing.

Not satisfied with the edge distance between the fiberglass and aluminum of the Horner tip, I made a fix. Using some of the newly discovered extra aluminum packed in the crate, I made what is essentially a splice plate to extend the aluminum. It works really well and can not be seen since I have it tucked underneath the fiberglass.

I also fit the left wing's position lights into place. This was simpler than I expected. I made a template out of a box laying around. For the larger hole I used the unibit for an initial 7/8th" hole, enlarging it was a rasp for a perfect fit.

The light itself is of a different size than Zenith's so it has a bit of overhang, but does not look bad.

In total, about three hours were spent on Saturday.

An hour was spent getting the wing tip cover into place and drilled. On the next wing, my process will be to place the wing tip cover BEFORE the fiberglass tip to make sure I can get a good edge distance on the Horner part.

Zenith precut the wing tip covers giving you zero amount of play or trim. The quick build CNC parts can be a blessing and a curse.

I spent two hours getting the fiberglass wing tip fit as good as possible. It is not a perfect fit, and I decided to shim a bit on the leading holes, but the fit is not poor. The (L) angle that attaches to the spar extension was also cut and drilled into place. The manual suggested 250mm for the piece, but then I would not have had any overlap. 280mm turned out to be the magic number. 285 or 290 may have also worked with some trimming.

These tips are notorious on the Matronics list, so I feel like I almost got off easy.

What really would help ( LISTEN UP ZENITH!!! ) would be to ship the tips with flanges that are at least another 10mm.

I could get the wing tip flush, but I would not have had anything to drill into!

I spent three hours and completed ALL of section 6A. The top and bottom tip angles were both crimped and drilled into place. The wing skins ( top & bottom ) were trimmed. I even placed in the fiberglass tip for a test fit.

I spent about four hours on the wing today before getting blocked. We put the nose skin back on ( I can't wait to not have to ratchet strap anything again ) The top and nose skin were drilled to together on the outboard side along with the spar extension. The slat supports were also drilled into place.

The wing tank stills needs to be tested, but I want to wait until my Jeep's tank needs a little fuel.

The blocking issue is the fluting / crimping that needs to be performed on some extrusion so the wing tip can be placed. It's amazing what extent some of the prefabrication on the CH-701 is, providing predrilled skins, assembled spars, ect... but in the same breath expect you to flute extrusion without even telling you "oh, by the way... buy a pair of fluting pliers" is just strange and inconsistent.

So I attempted to make a pair with some wood... that didn't work out to well. That excursion took a few hours. Hopefully I can find a pair to borrow... that or UPS will make a ton on overnight delivery from me.

Is it just me, or does the AMD Patriot ( aka Ch750 ) look more like a Cessna than the Cessna 162 Sky Catcher? And yes... I'm drooling over the 162... and yes I want to be the first to fly one when they make their way up here.

I only spent two hours on Saturday, but they were a productive two hours. The ground wires for the fuel tank and sender were attached and crimped.

Also I decided after much debate to run the PVC conduit through the tip ribs taking advantage of their tooling hole to secure the PVC. The root tip rib will need to have it's tooling hole expanded slightly to fit the wire, and a grommet will have to be added.

The top skin had the filler cap hole cut. I intentionally cut a slightly larger hole than I needed, and I'm glad I did. The filler cap is just touching one edge of the hole. I'm not sure what to do about the small gap in the skin.

While looking for my wire crimper I found a scratch built CH-801 that was first started while I lived in Texas. It was finally finished a few years ago and is in good shape for being packed away and moved across the country a few times.

The wings, nosebowl, rudder and stabilizer had all been removed. There are a few punctures in the wing and fuselage, but those will be easily repairable. I spent some time repairing it and reattached everything.

It of course is a scratch built stick and tissue model. Right now it is hanging off my right wing next to my DH2 Beaver.

It's on wheels right now, but floats should be easy to fabricate up.

I spent about two hours on misc items that needed to get done on the wing. The filler cap hole template was made, but not without complications. I'm not sure how Zenith expects you to back drill into the scrap. If the tank is in place ( which it must be in other to align the template ) then you can not possibly fit a drill between the tank and the spar to drill into the template. Also, fitting a drill from a rib would be another feat.

Instead I used a sharpie to mark a hole in the template from the rib, drilled that, then used a sharpie to mark the hole from the rib, then precision drilled that hole.

The strobe wire was cut, and I expanded the two tank rib tooling holes to fit the wire. The rest of the wire is in PVC. My thought was if I could further expand the tooling holes to fit the PVC and therefore be able to feed the wire all the way down the wing. The two concerns I have are 1) would expanding that hole cause need for additional reinforcement? 2) would the required bending put strange stresses on the wing?

I corked the left tank along with the tank channels and then spent time figuring out the path of insertion.

With the channels in place the fuel tank will not fit. Instead have the inboard channels clecoed, insert the fuel tank and then slip the outboard channels between the rib and tank via the lightening holes.

I measured as best as I could for the placement of the fuel drain and fuel supply holes, but missed a bit. The hole in the rib was closest and was only enlarged a tiny bit. I may consider adding some scrap aluminum to the fuel drain hole just to make it look better.

It took about an hour to get the fuel tank channels drilled into place on the left wing.

The approach I took was simple: predrill the ribs then match up the channels on the flange. The top hole on each channel was drilled on the workbench first and then clecoed to the matching hole on the rib. This made clamping easier.

The determine where the holes went on the rib I eyeball centered the channel marking the top and bottom edges, and then measured the edge distance as the top and bottom holes. The remaining holes were set evenly by eyeball measurement.

Most of the night was spent talking to neighbors about the project, and an hour was spent building.

The tank channels were cut to size and an A4 hole finder was fabricated.

I also stopped by a NAPA and acquired some wiring supplies for the fuel tank.

The hole finder was simple to make using some scrap from the slat hole skin supports that I made in the incorrect direction. I kept some of the flange to provide stiffness. At first I had the rivet head centering the tool, but that didn't work too well on A3 holes. Flipping the rivet so a partially pulled rivet's bulb does the centering worked much better.

It was a two hour battle to get the fuel sender into the tank, but I won.

Luckily there was a Tacoma Screw literally right on the other side of the highway from my office, and they carried unibits and a fly cutter that fit my drill.

First, unibits are expensive.

The night started with me testing the new fly cutter on some scrap metal. I clamped the metal to some beams to simulate the flexibility that the fuel tank would have. Then I made a pilot A4 hole. With the circle cutter, I found that the metal flexed ( predictable ) and caused the cutter to hit unevenly and snag. Luckily snagging did not cause any tears or dings.

The solution was to use the drill to score the metal and then hand rotate the cutter until the hole was made.

Next came the tedious process of deburring and slowly enlarging the hole from about 57mm to 59mm. I spent almost an hour on this alone so as to work slowly and not accidentally oversize the hole.

Finally the sender slipped in and I was able to tighten the screws. Unfortunately I had the unit upside down as I found out when I used the Ohm meter to test it.

Sunday was spent preparing for the fuel tanks. A few rivets on the bottom wing skin still had to be pulled by hand as well.

The manual is slightly confusing in it's instructions for bending the fuel floats, and I couldn't find the schematics anywhere in the plans. In the end it was best just to look at the photos for clarification. I'm not sure if my skills with pliers need work, or if I'm weak, but it really took strength to make the required bends.

I practiced with the circle cutter and found two major problems: 1) None of my drills can take the shaft 2) Hand rotating it only causes the metal to rip.

Therefore I need to figure out a better way to cut the circle OR I need to buy a drill press.

Arlington 2007 ( Saturday )



Edit: Since the first posting of these photos, I became unhappy with the color balance of a few of these "prints". Since then many of these have been readjusted to my liking.

If you want any of these photos in a size larger than 1600x1200, just drop me a line.

Monday night I got the nose skin drilled on the wing. I also finished the pilot holes from the nose skin into the top part of the spar.

The kit that Zenith provides has the front edge of the top skin predrilled, but not the nose skin. This is a problem since the nose skin overlaps on top of the top skin. The get around this before placing the nose skin, the top skin had several holes drilled into it into the spar which were marked with a sharpie on the skin.

When the nose skin was ratcheted on, I slipped it underneath the top skin and drilled those few holes using the lowest speed of my drill so I could find the matching spar hole beneath it.

Once those holes were clecoed, I then drilled lightly through the skin, trying not to enter the spar.

Once all the holes were matched, I slipped the nose skin over top the top skin, clecoed through the skin into the few holes that were in the spar, and then drilled through the remaining matched holes into the spar.

To help move the nose ribs into place, I made a hook out of some PVC that was laying around.

A few days ago I ordered my fuselage kit along with the bubble door option. I also ordered Jon "Crash" Croke's fuselage construction DVDs. I'll have a review up in the next week or so.

Also on it way are inspection plates and my lighting system. I decided on going with a ready solution since I would still have to match a driver unit and get the lenses.

Here is the Wick's page on the GS LED unit I will use: http://www.wicksaircraft.com/catalog/product_cat.php/subid=7000/index.html

There was no working on the "Sky Jeep" over the weekend. Instead, the real Jeep was taken out and given a proper workout.
