Ebike servo tester throttle

Potentiometer throttle to use with servo tester.
I designed this throttle for my custom Ebike, I'm using helicopter ESC (speed controller) and I needed some easy way to control it. It will work with any Car, boat, plane ESC.
Easy way to control brushless motor is to connect its 3 signal wires to servo tester.

Just remove potentiometer from servo tester and attach new one (20kpot) with extension cable.

Parts:

20kohm potentiometer
GT2 180 belt
2x M3x35mm screw
4x mini M3 bearings
1x
