Good to see this Thread is still alive.... My bear has taken a long long nap... about a three year nap and is getting ready to come out of hibernation.... If i remember Correctly I've already made the upgrades in the tail feathers, moved the Servos into the wing and installed brass and carbon fiber spars, now i need to tear into the main Wings and replace Everything! lol, My bear is being Powered by a BVM 91 Ducted Fan Engine... Should be fun.
