Thumb throttle for servo tester

grabcad

A simple thumb throttle is designed to house a cheap servo tester. This one works on a car ESC so only has half the full servo throw. I set it up to go from middle to full, but you could adjust it to do any part of the movement. If you want one to work with the full throw of a servo, just shoot me an email and I'll draw that up. To build this throttle, you will need 5x m3 bolts and 2x M5 bolts and nuts, plus some tiny rubber bands to make it spring back into shape.
