The magnets need to be re-zapped (which, in turn, magnetizes the motor frame). Those old iron slug motors don't hold a charge for very many years.
You can search the 1/24 sites for somebody to do it. I did that a few years back, but for the life of me can't remember who it was!
- or -
1. stick some neo's on the motor frame (careful of the polarity). Sometimes they help to remagnetize; mostly they act like a can-type magnet.
2. replace the iron magnet with neos. Stick a bunch together using steel shim (or cut up a steel can if you can find one) as spacers if need be.
Remember, with those motors it's the magnetized frame that makes the armature spin.
