Throttle Knob for DC train controller

Here's a replacement throttle knob for MRC powerpacks or anything with a 6mm "D" potentiometer post. This throttle knob will let you actually see what percentage you're setting it at unlike MRC's with the actual knob covering the numbers. Requires a 1/4" x 3/4" cap screw. Depending on your throttle pack, you may need to apply a small felt stick-on pad under the arm if it drags on the powerpack unit itself.

Update: I've included a 180degree version of the body for some MRC controllers that have the pot set 180degree opposite. Take note of the flat spot of the pot on your controller, and choose accordingly.
