RE: Help! Need "first principal" assistance
disaster! I let the club secretary fly it on its maiden flight. went 100ft up, then 100ft down. crunch. plenty of pieces.
On closer inspection, the tail fin had been incorectly cut (by Ripmax) and this introduced a silly angle of incidence between the T tail and the wing - result, an uncontrolable climb.
I sent the pieces back to Ripmax 3 months ago. Only received a replacement on Monday, so back to the dining room table to re-build it!
I hope you have a better maiden flight - watch out for the angle of incidence!
