Never crashed my MX450, had some hard landings with broken tail rotor blades and thats about it as far as damage.
I crashed my T-rex very hard nose in on a baseball field, if I had been on asphalt it would have been destroyed. The heli had broken main blades, bent tail boom , bent flybar , bent main shaft, broken battery try mount, broken fiberglass canopy, striped main gear, striped 3 teeth off the belt. The head had no damage other then the main shaft.
I had been flying alot at parking lot near my house, after that crash with the rex I realized if I had been at the parking lot I would have totally destroyed my rex.
