Radiolink RC6GS / RC4GS Steering Thumb Control

This is a thumb control for using the controller one handed for the RC6GS and I believe the RC4GS (the wheel should be the same). 

Just remove the center sticker of the wheel, remove the bolt, remove wheel, slide over wheel/under foam and reinstall. It's a tight fit. To adjust it where I need it I turn the wheel to it's stop and keep pushing, it will slip on the wheel when pushed hard enough.

Should fit the following transmitters but only the RC6GS has been tested:
