Need new motors? Grind a gearbox? Adding teeth to a pinion?
#145965
I have a Dune Racer PW that has a bad motor. I'm looking at replacing the motor but have some questions. Firstly, I was looking at the Hobbymasters guide to buying replacement motors and became confused when they are talking about the 550 21 Turn 14 Volt with reverse rotation. What is the purpose of the reverse rotation? Is it for the actual going of reverse on the PW? Do both replacement motors need to have reverse rotation since the Dune Racer can go in reverse? If I use the non-reverse rotation motor, will my PW lose the reverse gear? Any help to clear this up with be greatly appreciated.

DC motors are reversible. The purpose of a reverse rotation is in regards to DC motor timing. Stock motors have neutral timing so they run the same speed in both forward and reverse. Some motors are timed to run faster in one of those directions. matching a timed motor with a timed reverse rotation motor will yield you a matched pair of timed motors.
