Hey Jerry,
Going out to propwash today to do a little crow hopping. Come on over if you
want a place to fly to today.

George

Has anyone noticed the J series wants to climb. I took mine into the pattern
for the first time yesterday and it took quite a bit of stick pressure to
bring the nose down in the downwind leg. She flies just fine, but seems a
little tail heavy. Crow hopping didn't give me this indication. I admit to
not trying to trim the elevator in flight. I was only doing patterns and
didn't have the time in a pattern to really play with the trim.

George

For the first flight in my J, I didn't know where to set the trim. I was
concerned about it getting too nose high on take off so set the trim for
lots of nose down. I had to really pull hard on the stick the entire first
flight. But I have it dialed in now and it flys level with very little
pressure to climb or descend. My CoG is near the rear of the range, which I
suppose would make difference too.

Hi Jerry,

I was out there again today. I think I've got the trim pretty close. She
still wants to climb just a bit. Now I've noticed a tendency to want to roll
left, just a hair. Any ideas as to what that might be?

George

My J has the same very slight tendency to roll. My guess it is caused by a
slight difference in the wing washout from side to side. It seems like I
saw a trim tab on the wing of one of Mark's planes.
It sounds like you are having some fun. Are you flying it without the doors?

Hi Jerry,

Yeah, It flies great without the doors. Since the area where the gas tank is
is covered, there is no significant cupping effect, so it flies just fine. I
also took the lexan off of the port side as well.

Thanks. I was feeling a little bad about the roll. I'll try adding a small
trim tab on each aileron.
