Thanx Rusty. Yep, I one of those OCD
(obsessive compulsive) type people. If it ain’t perfect then fixate on
it! You’re absolutely right about getting comfortable with the
plane. That’s mostly what I did today- lots of turns, climbs, and
descends. But in case of emergency my landings suck! They don’t
suck if I actually get it down close within the first 1/3rd of the runway.
But I’m tending to come in way to hot and high. It took 3 passes today to
get it down – when I did on the 3rd try it was a “greaser”
– but if I’d had to land on one of the first 2 approaches I would
have been touching down about where the end of the runway was! So, next
time I go out it’s going to be a lot of pattern work. I want to get that no-power-landing
nailed so I can pick a spot and land on it if something ever does go wrong.
ThanxAgain,

Flights -
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.
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!

is about 5 minutes)
