RE: cg for a world model's ultimate bipe. .30 size
I also have one of these planes, bought it years ago and just now started it. I pulled off all the pink,white and blue shelf paper and I'm in the process of recovering it now. anyway my book lists CG at 81mm from the leading edge of the top wing, no range is given. The control surface throws are
Elevator 10mm up and down
Rudder 30mm left/right
Ailerons 5mm up and down
John
BTW i think World models has the manuals aviable for down load
