Radiolink RC4G/RC4GS/RC3S 3rd channel button presser

thingiverse

I was using the RC4G for drifting. But I found the trigger inconvenient for braking - too much travel and impossible to find the exact position for the right amount of throttle afterwards. So, I decided to use the third channel for e-brake (or fourth as Radiolink calls it, since it names #3 for gyro sensitivity). Programming it was very easy, and the button was correctly set up for use as an e-brake: only active while pressed. The problem was, of course, the positioning of the button: to press it while playing, you need a thumb with at least three joints! So I designed this little 'button presser'. It slips around the gyro sensitivity adjustment knob which holds it tight, and with the index finger you press it and the pressing goes to the button. It works as a charm! Two variations, with different size above the button. I think the 2mm one is perfect. The TrackStar D-Spec TS4G seems to be exactly the same box, so it should work with it also.
