Converting 4 wire Steering Servo to 3!
 
I have a mini-t and swapped electronics but havnt gotten my steering servo yet, im curious if theres a way to use the stock 4 wire servo on a 3 wire connection and what all is needed! Thanks :)

got some bad news u cant convert a 4 wire to 3 you can only make a 3 wire 4 wire that way u can use a different servo with stock electronics .sorry

yes you can. or, at least, i can.
 
what i did was i used the circuit out of two other unused servos with three wires and soldered them onto the 4 wire servos. i used the original potentiometers and motors from 4 wire servos for compatibility reasons. taking note of wire placement on the potentiometers and the extra wire (black) on the 3 wire servos that was soldered onto the outside of the servo motor. it was easy. the whole thing took about 30 min. main thing is, use the original gears, pots and motors and just replace the circuit and wiring. leave the wires long on the donor circuit. spectrum 3 wire circuit to losi 4 wire servo. works great.:nod:
