08.22 Swift 550 Crash

2nd crash of the day- first one was a botched autorotation landing which cracked a very nice carbon fiber RotorTech 550mm blade and snapped a linkage. After swapping out the main blades and a swashplate ball-link, I took it up for a test flight to track the blades. Amazingly enough, no adjustments were necessary so I put it down to attach my still quite dull canopy and enjoy a couple more flights. Wrong. I discovered the fastener for my left-side swash servo's arm had come loose since I probably forgot to use loctite. Aside from the blade destruction, only a few teeth are broken off the main gear.

RT 550's are about $90/pair. The tailboom is in its stock location- low boom design that depends on tall landing gear for tail rotor clearance and an underslung battery. I prefer tighter CG of having the pack up high. Modding the tail at 45° allowed low profile landing gear, which addressed ground resonance issues. Since the tail rotor chops less disturbed air, performance is supposedly improved, but shortens autorotations fr extra belt drag. This heli is just for sport flying. cheers-

Not a shabby parts list for that repair(even though rotortech 550s are expensive)? I noticed you had a lowered boom and 45 degree tail. Were you gonna make it scale or does that just enhance sport flying in some way?
