Propellers and time warp

So I spent quite a few hours getting an electric quadcopter together to acquire some kerbal surface scan missions that were far away. I finally got the thing flying super stable. However it's top speed is only about 40 m/s. Going to x2 time warp instantly makes the propellers move radially outward and then simply explode. Does anyone know of a way to successfully time warp with propellers and rotors? I tried moving the blades radially inward into the rotor a bit and turning on rigid attachment available under advanced tweakables. Neither worked.
