Step 2Modify the servos
You will need to modify your servos using the super glue the potentiometer method. I chose not to waste space by detailing it here as there are dozens of articles on Instructables and Google showing you how. If demand calls for it I will add it here later.
Essentially you need to tear them apart, find the 90 (no movement) position, super glue the pot top and bottom, put it all back together, modify the output gear, file off the top of the pot shaft flush with the case mold.
The Hitec HS-311 has a plastic pot shaft that makes it easy to file down. If you use a different servo that has a metal pot you must alter the underside of the output gear instead.
Potentiometer = Pot = Variable Resistor
