Mabuchi motor variation?

2020 Views 14 Replies 9 Participants Last post by  MRE
Evening all, has anyone noticed the extreme variaton in performance among the Mabuci motors that Scalextric and Fly are using lately? I have just been handed a most disappointing Scalextric Camaro. It was supposed to run against their Mustang. The chassis are the same, sidewinder layout. Length and track are the same. The Mustang runs a 4.2 second lap (best on 55.3 feet of track) The Camaro barely runs 5.3 seconds. Two weeks ago I bought two Fly 917 porsches, one runs 4.8 seconds, the other 4.4 seconds. they are tuned identically for competition with each other. .4 seconds is a very large gap on the track. All these cars have their stock Mabuchi motors. The faster motors have been switched among the cars and the variaton lies with the motors. I'm considering always buying the Slot It motor, the way I always buy better tires and magnets when I buy a new car. (So I can spend more money to field a car.) I'll stop whining now. Anyone else?

All mass-produced motors have a production tolerance which can make a big difference. Just ask the serious racing guys.

We stock the Scalextric motors, and regularly get customers wanting to run them up to hear the tone. Some are real screamers, some are noticeably slow, but most fall into an average 80% band.

I think you'll find most racers have around a dozen motors in their pit boxes, as revs are not everyting. Sometimes a slow sounding motor can have more torque or resp[ond better to a poor power supply. This is normally due to the commutator timing which is set at assembly. More advance can mean more revs but at the cost of heat buildup.

Best adice is to try some different motors and see the results.

By the way, the type of car and colour of bodywork has no bearing on the motor performance. Anyone who thinks otherwise should ask themsleves why they beleive this ?
Always happy to be of help.
