Johnson Motors

Does anyone have tuning tips for the kit Tamiya motor. We race these motors at www.trcc.org.uk (http://www.trcc.org.uk) my local club.

If your looking to increase your RPM on Johnson motors, well RCCA did an article on it... and i hear Johnson motors are really good for a stock motor...

i know it goes something like breaking in the com brushes...

1. wire the motor to a battery
2. have the endbell submerged in water, but not all the way... only the endbell should be in water about half inch!?!
3. pull it out and spin dry the comm
4. add comm drops
5. lube the comm rod bushings
6. repeat the process... like 4-5 times

you should see an increase in speed and in rpm... i think you'll add on like 1500-2000 rpm

gee i hope i got that right... if anyone can add feel free to... ;)

What a coincidence, Bro's name is Glenn and my surname is Johnson. LOL. Back to the topic. How long do you run the endbell underwater? We race the same motors in offroad and onroad, how long do you dip the endbell for? I usually dip the whole motor in water for 1min, comm drops and oil and back into water for 30sec then add comm drops and oil the bushings left sitting for 30secs more. All on a fully charged 6 cell pack. I have only used this motor about 4 times so I still have to wait a bit to see the real outcome of this.
But, I have seen some racers hooking these up to a 12v battery or power-supply and running them in on 12v for about 5mins, then putting comm drops and oil on them. What does this do compared to a 6cell pack?

mmmmm im not really sure if it has any effect... if i recall right, just use a stick pack for now... cause usually the 540 motors use 7.2 volts not 12 volts... as for how long you keep it in the water, just submerge the endbell about a half inch or maybe 3/4 inch to be sure the comm is in the water... do this for like a min if i recall right... and repeat this as necessary... if you're wondering how well your motor is gonna perform try it out on a vehicle... test to see if you increased to better lap times... who knows, maybe you decreased your time by 10 secs :cool: hope that helps :D
