Thanks to Crash Recovery, I've had one of these frames for 6 days now. It has crashed into all the obstructions that I normally fly in and amongst. The frame has held up well and protected the other components splendidly. For all the impacts I have had, I am only down a few props. Some of the crashes have been hard enough to break solder joints, and still no damage to anything except props. The HMB 235 handles abuse well.
