AdR|aN - Do you have any access to a brushless motor? Also I'm not sure if you've ever run a johnson 540 but you could hit 20 minutes for runtime with one 3300 pack and they will only be a bit slower then stock if geared correctely(very high in most cases, like 5:1). Also they always run hot no matter what so you can really push them(if your track is flowing it may work). Also use stick packs with deans for quicker pit stops.

hiya fatdoggy.
Thanks for the input.
Nope. The race doesnt allow for brushless. If they do, i wouldnt worry so much.
I was thinking about using Johnson/Mabuchi 540 motor.
But how many packs before i change a motor?
I havent tried a 540 motor yet, hopefully will try soon before the race.
Thanks man.

You might be able to finish the race on one motor. They get so hot that you'd need gloves to change it anyway. To run them in drop them in soapy water at 3v for a minute or two. Clean with motor spray and oil the bushings. During pit stops blasting the comm with motor spray will clean it a little, just a short squirt will do. I'd suggest you do some testing with one just to make sure it'd meet your needs, gearing correctely is critical for these motors and if your off your car will be slow. These motors have crap all torque so corner speed is also critical. If your track is tight the johnson 540 may not work very well...

.... did some more testing today. I ran the 4505 brushes for a second run with the purple/purple springs and they killed the comm very quickly and power wasn't very good. Then I dropped in the putnam greens with a fresh comm. Dam they are friggin awsome, unreal the difference. More punch, more top end but at the end of the run the excessive drag of the purple springs made the motor die a little. I dropped on a red negative spring and the motor ran better at the end of the run. I tried a green negative spring with the purple positive but it jumped(sort of hanging brush effect) on the straight and when I punched it hard out the corners. The putnam green brushes are hard on the comm but after 5 runs they are still in good condition. The serrations last ages, after 5 runs I still have serrations over the full face of the brushes. Motor temp and batt temp was higher after the runs but not too bad.

My final monster racing setup for now, Putnam green+/green- and for springs, purple+/red-. I'll do some more testing with putnam blue brushes in the next few weeks.

Default Endurance race

AdR|aN - over on Big Jims forum there was a comment about using Trinitys Street Spec brushes (with the striped shunts) for an endurance race. They last forever and give pretty good power.

Thanks, I'll try out green/blue next time I go to the track. Has anybody run blue/blue before?

Fatdoggy,

Try a Hurricane Gold brush or Paradigm 2152.

You'll like them.

Brian McGreevy - Have you tried the new paradigm 21582 *magic brush*? Interesting that it has slotted face.

I'll try the Golds and the 2152's in a few weeks, probabley wait for the 21582's to come out and order a pair or two of them at the same time.

I haven't gotten to test the 2158 yet only because we're trying new things with it still, but it's nearly finished.

You can get the 2158 in any brush cut you like, standard it is full face.

I'd get the standard fullface 2158's, not the slotted 21582's.

Fatdoggy,

Might think about trying a Binary stock. Geared right, a decent binary will beat a decent monster any day...that's what I've seen even on very, very tight/technical indoor layouts.

I ran against a friend who had a binary over the weekend(must of had 8 runs on it) and there really wasn't too much of a difference. I had more top end but in the infield we were pretty much equal. If he had cut his comm and dropped in some decient brushes I'm sure he would have out powered me. Once I've got my monster at peak performance I'll be try another motor, probably the binary stock or the roar legal version.
