Hi, I just buy the Grand Tundra. The manual talk about for CG, 75/80 mm from wing edge, but with this measurement the plane is nose down 45°! I move esc and battery far back the CG and 40gr on Tail to have good center plane..... Some forum talk about 60mm for CG! Which is the right one, 75 /80 or 60???? My friend have the same plane, old version, and with havyest battery and 75mm from wing edge, is all in the right place (battery and esc in the front nose wit perfect CG). Why? What is wrong? CAN YOU PLEASE HELP ME? Maybe new version of this plane have different specs?
Thanks, waiting for your answer, Regards Lunazzi Sergio Udine Italy.
