ZMR250 Clone Frame 2208 Motor Protection

I'm building a 4S quad with 2208 motors. Total thrust is ~ 3.7kg. Quad will weights ~ 800gr with the 1.8 battery and RunCam HD. At this moment i can only imagine wich speed it will achieve. So, i decided to protect it as much as i could. ( I have the experience of braking arms, damaging motor bells and rip off the wires from the motor on the other quad =)). Didn't find anything that's fits my needs and i made my own Motor/arm/wires protection for EMAX MT2208 II 2000KV Cooling Series Motor.
