This is a 50 ohm wirewound potentiometer (often called a "pot") rated at 5 watts which is well suited to most 1/32 RTR cars. These pots are a direct replacement for those found on Difalco 1/32 controllers - while they are generally reliable, it is a good idea to carry a spare in your pit box. The threaded bushing is also long enough to mount into a driver's panel/station that is up to 1/4" thick.
The standard pot rating, for both braking and sensitivity, on many Difalco 1/32 controllers is 25 ohms. Some racers prefer a 50 ohm pot as it offers a wider range of adjustment. This pot could also be mounted to a driver station if desired.
Potentiometer includes a retaining nut.
