2nd crash gyro off

[jeff250]

Just got my mx400 pro back together. It crashed while doing a loop, last time. Looked like the stock blades may hit the boom behind the horzontal stab while pullin full elevator. I put new trex 315 blades on it. New trex tail slider and trex blue aluminum tail blade grips . Also put the trex boom on it. I wasn't getting a very fast aileron roll so I put the trex carbon fiber look paddles on it with the 220 flybar. Seemed to fly alright gave it full elevator no problem. The speed was still slow. The neighbor had the gorilla paddles, I took the weights out after a flight. And wanted to see how fast it would do a stationary back flip. Pulled full elevator and heard something hit then I lost the tail and spun out of control. Crashed. Looks like the tail boom , blades, tail pitch slider and landing gear need replacing. Nothin loose on the linkages. There is a dent behind the gyro as if the paddles or and the flybar hit the boom on the right side and then knocked off the gyro. There was a rubberband on the gyro keeping pressure down on the tape. WONDERING if this is possible?? The 220 flybar is longer than the stock flybar and the gorilla paddles are even longer than the trex paddles.

After closer inspection I don't know if the paddles could have flexed down and hit the boom. I didn't put no ca on the paddles either and they screwed on easy . Also the belt was loose but i think the crash did that cause the boom was pretty tight. I didn't put any locktite on the tail hubs grub screw. It is possible it spun. Hard to tell when a lot of things loosen in a crash.
Even my motor pinion moved up on the shaft and I had locktite on it.
