GOTCHA !! I thought this thread SUBJECT might get your attention!
What I really wasnt to know is....Is there ANYONE flying the big UCD with a .61 engine with positive results ? I'm an old fart (72) that bought one because I just because liked the way it looked ! Real cool .
Anyway, I'm gonna put a OS .61 FX in mine and fly it just for fun. There a few UCD's "Flying" ( Hogging the runway) at at our field and frankly They bore me to death, kinda like Pattern ! (Oops, Flame time! ) LOL !
All I want to do is some basic maneuvers and a few touch and go's.
The manual says that you can Hover with the .61 ....But is anyone flying with the lower end engine and enjoying it ?

Thanks Guys,
Ugo
