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.
