Reached 10 hours in the air. Changed the oil and did another under the cowl inspection.

All indications from the magnet filter and oil look good, break in is going well.

Found some evidence of an oil cooler fitter rubbing against the engine mount. This was more flex than expected. The filter was moved and secured down additionally to stop this.

After adjusting the turnbuckles more, it appears that 18lbs tension is the magic number. The slight left turning bias on the ground was traced back to a trailing \ not yet broken in brake pad.

There is still more friction that I would like in the rudder system, so I will install the rolling bearing mod on the nose strut.

The airframe now has about eleven hours in the air.

Frabricated a securing mechanism for the passenger side door.

The fix is basically a thick piece of angle riveted to the top side of the factory supplied handle. I then drilled a hole in the free side of the handle and bolted a rod-end there.

The rod end was connected to all thread. I then riveted a piece of tubing onto the door for the all-thread to be retained by. Finally I drilled a hole large enough for the all-thread into the fuselage.

I also spent a large amount of time chasing down friction in the rudder system. The biggest offender was a huge spot I had not greased - the nose strut stop plate! I ended up just giving everything more doses of grease, even the nylon fairings. With the tail tied down I was able to reduce the friction by an order of magnitude.

By the time I was finished with all the other work today the winds had picked up past my threshold. I did a taxi test and a run-up. The door held without any pucker on the ground where it had previously puckered some during run-up.

Taxi tests with the newly loosened steering system were highly encouraging. Friction for ground handling has been reduced to at least a quarter compared to the first flight.
