Hi All,
I'm not there yet, but, I have a new Lycoming O-360 and in the process of
building a homebuilt kit. Lycoming says to break in the engine at full
power
and gives procedures on how to do it. The kit needs slow taxi, then fast
taxi, glazing of the brakes. After take off there are procedures to do at
lower power.... I know I'm not the FIRST in this dilemma, so what takes a
preference? If you wait to do the full power to seat the rings, is that
ok?
Thanks for any response, I'm at a loss,
david

The brake break-in procedure only requires a few minutes of taxi time and a
couple of stops, IIRC. On my RV-6 (I assembled the airplane rebuilt the
engine myself), I probably ran the engine 10-15 minutes before the first
flight. First was a short run to make sure it ran and didn't have major
leaks. Then was a short run to taxi the airplane the length of the taxiway,
performing the pad break-in procedure.

The third time I cranked the engine, I taxied to the end of the field, ran
up the engine, and launched into the blue. Of course, I had done LOTS of
work to verify that all of the controls had good continuity and the aircraft
was properly rigged. I've known too many people who had trouble due to
sloppy rigging on the first flight.

It is attention grabbing to make the first flight of any homebuilt aircraft,
moreso one where you built the engine too...
