I used a CF tube as a spine that doubled as sheaf for the elevator pushrod - bad idea, as the rod didn't compress like the rest in hard landings, so the last free inches of the pushrod got bent time and tine again! I would - if I built a new one - use 2-3 thin (1.2 mm) CF rods to stabilize the fuselage. Nothing more is needed! In case of a heavy crash the front part of the rods will break, thus saving servos, et cetera! Tord, Sweden -- If reply difficulties - use [EMAIL PROTECTED] Tord S.
