ill add one point. make sure the front landing gear is seccure. mine and a few others that i had talked to the front landing gear was bezeled at the wrong angle thus causing the plane to taxi at an angle. if you have this problem i would suggest refiling another flat spot on the landing gear and get it set straight to begin with. also most folks dont hook up the flight stabalization system. leave the wing tips on till you learn. and myself i wish i had trained without those flaps.. but if you do install those flaps and get the plane trimmed out just right, when you romove them the plane will be way out of trim. so you might want a trainer to remaiden your plane after the flaps are removed.
