I also ran the engine hard - full throttle - for about 30
minutes in mostly straight and level flight - but with the gear down still. I
was getting 140kts at 5300RPM - but that's all I could get. The oil temps were
also hitting 200 degrees - so I backed off and let things cool down to
180.
Hi
Joe,
So far, your testing
seems pretty uneventful, which is great! I would advise you to
stop worrying about performance at this early stage, and just concentrate on
reliability, and initial airframe testing. Sounds like you
have plenty of power to fly the plane, with good temps, etc, so just use
the first 20 hours or so to get completely familiar with the plane, and put some
time on the engine. Once you're totally comfortable with the
airframe, then worry about power and performance. When you start
pushing the engine, is when thing's are more likely to break. Hopefully,
nothing will, but if it does, you'll be glad you have all that quality time
under your belt already. Hey, you might even have insurance
:-)
Most folks go through a
number of iterations before getting the performance they hoped for, so just
expect that will be the case, and be pleasantly surprised if it
isn't.
Keep up the great
testing!

sunburn endurance, which is about 5 minutes)
