RE: GP ultimate Bi-plane, finally finished.
Dragonov3,
I have a GP Ultimate 40 size on the building board now. I have completed the stabs, rudder, and elevator halves. Like you, I plan to use two servos in the lower wing. I have the lower wing almost done except I need to flip it and sheet the lower part. I have not started the upper wing or fuse. I appreciate any hints you would like to share as I build the rest of the components. I plan to install a Saito FA82 that came off of my Funtanna 40... R.I.P. I will probably mount it inverted but havn't decided for sure. I know that is overkill but, the motor will keep me from buying one and I'm pretty good at throttle management.
