[rebel-builders] Elite - It flies.........

Congratulations Mike !!!
Like that smile !!! :-)
A 45 degree angle isn't far off - you want the prop to be coming
up on compression at about the 10 o'clock position, viewed from
the front. This is perfect for hand swinging, if you ever have to
start it that way. Sometimes just moving the prop 1 hole can
make a big difference ...
Sounds like the oil's a bit cool - maybe block off more of the
cooler to get it above 180 degrees anyway. That might account
for a bit of rough running ....
Having the ailerons out shouldn't matter - if you let go of
the stick, they should equalize. If it still rolls, I'd have a real
good look at the wing tips. Almost all of the Rebels with the
original tips rolled - about 95 % of them to the left .... It turned
out that one tip was about 1/4" lower than the other. It's VERY
difficult to build them even, when you're glueing together
pieces of fiberglass ! If you can, just lower the rear of the right
tip a bit - doesn't take much. It's always better to add a tab
on the bottom, lifting, than one on top pushing down.
Drooping a flap will work too, but may not be necessary...
Before you do much with the tips, be sure the ball is in the
center when testing .... if the fin is offset, you could be yawing
a bit, which would create roll .... Not usually a problem
on Elites, but worth checking.

Wayne,
You may have something there. The prop stops on a 45 degree angle. I was
shooting for parallel with the ground but hit it wrong I guess.

Dang...what a goofy smile on your face Mike ! LOL
Glad all went well !! CONGATS!
The vibration may even be the exhaust system noise at full throttle, but
if
it is the prop....many a vibration has been solved by simply rotating it
180
degrees. I'm also assuming that when you shut down it indexes properly and
stops in the "hand swing" postion.

Well everyone, N771ME Elite flew today for the maiden voyage. This was
the
first opportunity with out wind to make a flight. The rest of the week
looks bad, but have some adjustments to make in the mean time. All went
well. Outside temp at 35 F.
Climb out was around 2450, oil temp made 155, EGT 1400, CHT
highest seen was 375. Air speed indicator looks good.
I notice at full throttle the engine has some vibration, but at 2400 it
is
smooth as glass. I think it is a rotation problem up front related to
balance and not an engine running condition.
2 problems, it flies out of trim right wing heavy. Almost looks like the
left aileron is drooped slightly when the other side is neutral, at least
it looks that way in flight, but it looks that way on the ground too, not
sure if that adjustment will correct this or not. Maybe droop a flap?
Second problem is flap lever won't hold detent. It looks like the detent
bolt isn't going to the bottom of the notch far enough. Going to have to
change something and try again.
Also planning on cutting the oil filter to make sure all is well before
going up again too.
Thanks for all the support this group gave me for 2 years. Hope I can
help
someone else in the future.
