Mabuchi motor variation?

2023 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?

Well when you are dealing with inexpensive (read Cheap) motors with a 10-15% variation allowed in specification tolerances, what can you expect? No motor maker for the home set market can varify that their motors are with in even 5% of each other. Just not going to happen for the cost involved and the time taken to make them.

So take it as the standard and start looking through a bunch of motors, to even find some with in 3-5 percent of each other.

If you insist on running so called box stock classes, you are going to put up with this problem, of out of tolerance motors, gears, wheels, and tires etc. Box stock racing does not exist in reality anywhere.

Racing fairly, only exists as you allow it to evolve with gradual improvements to the over the counter cars. How far you go allowing this. is up to your organization.

In my humble opinion!
