Justin, I've been flying my older version F86 for the past year. I have logged many flights on it.I'm using the bvm bypass and a AMT 180 tuned to about 15 #. The turbine upgrade kit sold by BVM had a carbon fibrer former for turbine mounting and wing bolt retainers. Also additional wing mount at the leading edge are used.I used no reinforcement in the tail area. I don't have the speed brakes either. The main thing while flying this bird is to watch the speed. I try to keep it at a moderate speed( aprox 150 mph max). If all flying surfaces are tight you shouldn't have any problems. I would recommend the gear plate stiffeners BVM sells for the mains and the aluminum nose retract rails also. If you have any more question I'll be glad to help.Scott
