Hello, I purchased a plane from a hobby swap meet a few months ago. The seller built it, and covered the wings, installed servos, pushrods etc. I covered the fuse,stab,rudder,elev., turtle deck (all balsa) installed a never run-in OS 90FSR Which I ran in with help from fellow club members, and it is running GREAT!! -ANYWAY...I installed my new Futaba 6EXA
Radio and servos, I now need to know CG for this plane. I have no plans or instructions, I don't know what brand of kit. It looks like a 300 Extra or that type of aerobatic plane.The wings measure32-5/8"L and are 15-3/4" at the root and 8-3/4" at the tip. The overall length from rudder to cowl is 55". the Fuse is 7-1/4" wide. I hope this isn't too much info. I need help determining CG and beginning control throws movement. Since I have my first computer radio, I can use low rates or whatever I need to do. I just want to avoid a tail-heavy,super sensitive beast on the maiden flight!!! Thanks in advance for all input!
