Radiolink RC3/RC4G/RC4GS Wheel Donut

thingiverse

Outer donut/wheel for a variety of Radiolink radios. The original foam donut does not fit that tightly on the Radiolink radio and the wheel itself has a pretty small diameter in comparison with those from Futaba, Flysky, and Airtronics. This matches those much more closely while providing a better grip and improved control. To install, unscrew the center wheel and pull it off the transmitter shaft. Pull off the foam donut and replace it with the TPU printed version. NOTE: This is intended to be printed in TPU. It may work in a non-flexible material, but the dimension for the inside would need to change for it to fit properly. This is intended to have a very slight interference - but assumes that you are printing at a pretty high flow rate so if you print this and it is loose, change your settings to a higher flow rate to adjust or modify the model. UPDATE 02/12/22: Added an updated version with slightly different cutouts and slightly tighter fit (probably imperceptible).
