Bigger Controller Knob for FUQI FQ777 Quadrocopter

thingiverse

I really like the FQ777, but the short knobs of the controller gave me a hard time flying accurately. These longer controller knobs make it a pleasure to fly. Simply pull off the original short knobs and push these on. The long knobs can be stored in the spare-part compartment of the remote while carrying, so the controller will still fit in your pocket. You can keep the original knobs there too, so you can switch between the two as desired.
