Some will say the older mabuchi and johnson motors are better made, others will say it depends on how you look after the motor.

Imho I dont think the newer motors are quite as fast, and/or drop off performance quicker, but that is a very wide statement to make.

Brasso & (cutting fluid 5%) submerge to just cover brushes 8-10mins @3volts
Clean in water then spray motor cleaner.

Redip every 3-4 runs 1-2mins

I guess it depends which one you use? Maybe there is a certain chemical in some that is detrimental to the brush performance. I could be looking at things in too much detail though
ive done that before and the motor died in the very next race. i will never spray that shit on anymore. just keep applying com drops through the motors life

Hey bit random. Just interested to know which motor sprays you use. What brands, or any other random industrial stuff.

Cheers Haydn

Bout a year ago we did a 12hr "mini" enduro.. Using a silver can in the tamiya mini, our car ran 12 straight hours (minus pit stops) and i think it was faster at the end of the event than at the start. But I was pretty tired at that point. LOL

Thats a lot of club races though!!! Just oiled the bushing once an hour on the endbell.

with stock motors I never spray the can, just the armature and a little bit on the commutator, let it all dry off then clean the commutator with a cotton bud then skim it up

Seeing as that process is too difficult with a 540 (and not legal too!) I am a bit wary of motor spray on 540s too, but you dont have much choice really as commutator drops on a sealed can motor will just eat into the commutator and will burn onto it

Hi,
I have a newbie question.
Break in refers to running until the brush sits fully on the comm?
does this apply to all types of brushed motors?
I got a little confuse from another thread when someone ask about break in Tamiya Sports Tuned as Sports Tuned brush are jagged(teeth) and it says 2x2 at 2v. Don't need to fully seat the brush on the comm.

Supra,

29.000 BUT.....
The motor was a dog
When I put this motor in a car it couldn't get max rpm by a longshot.
There was no torque left in it.
An avarage motor was at least as fast.

Max rpm ain't everything, dude....
