With well under 10 hours of flight time since new, I had the belt on my Jetcopter SX snap yesterday during (obviously) the final flight..https://rc.runryder.com/rr/rrpv.htm...6/&IN=1&a=0&s=0
Of course, this never happens when we'd appreciate it most.. I was coming back towards the open field, above trees when it started wildly piro'ing.. It was obvious the tail was gone so I started to climb to an altitude that would give me a better chance for a successful auto, however as I climbed higher above the other trees, the wind speed increased substantially, pushing me exactly where I didn't need to go.. I shut the turbine down and did the best auto I could between two trees and over a brick and steel fence.. Having to get into the collective early to miss the fence ate up a bit too much head speed.. It didn't help I was only a minute or so into the flight and still considerably heavy with all the fuel..
Obvious damage: Main 800mm Rotortech's (the last Century could find in stock of the solid black), landing gear, front tray frame (bent - possibly correctable), tail boom (got whacked by one of the blades), spindle, possibly main shaft, and related.. Turbine starts up and runs up to full power fine with the head removed.. The landing gear probably helped protect it as it pancaked out.. Could have been much worse...
That all being said... In the past, I've had belts fray over time, but I've only had one snap in a wreck. This heli has been flown gently with almost no aerobatics.. I am unable to find what might have caused it thus far. Any thoughts/ideas would be appreciated.
