I've got two setups for all my motors.

Conservative club racing:
-very low silver, (copper shunts) on negative with orion green spring....full face, serated
-medium silver, (copper/silver mix shunt) on posative with orion red spring.....full face serated

"Big Race"....all bal!s out setup:
-highest silver possible on negative with trinity black spring
-highest silver possible on posative with trinity purple spring
- posative brush is serated with hole in face a little left of center
-negative brush is full face with very slight advance timing

I rarely ever get a CHANCE to race...of course I'm gonna take it..ANYTHING beats sitting around my house with NOTHING to do.

Plus, I don't make enough in a week to get a motor if I save it all up...plus I gotta eat when I gotta eat

Isnt this considered a short stack arm ? Less laminates equals less wire length overall not making it a true 27 turn stock motor, isnt this correct ? Hence the higher rpm.

It is the same height, you just have more space between the 2 lamination segments. Meaning they removed them from the middle.

25/72 in the Evo3....

If I gear it any higher I'll burn it up (its already running hot & has no punch)
If I gear it any lower I'll get NO top end

Pretty bad predicament huh?

What would putting a Monster arm in a Core can do? Have you heard about anyone doing that?

The Black Kat - You may have overheated it on too many times and hurt the magnets. Try a 25 rollout(medium indoor carpet track) and go up teeth if you don't have enough rpm and down if you don't have enough torque. Rollout is a personal thing, everybody drives differentely so everybody requires a different rollout. Smooth driving = higher rollout. Aggressive driving = lower rollout.

Rollout is how far you car moves per 1 revolution of the motor.

Rollout = (Tire diameter x 3.14) / Overall gear ratio(final drive ratio)

Thanks Doggy...I was beggining to wonder what rollout means

I probably killed the magnets...Maybe I'll try putting this comm into a newer monster can & see how it works...I probably abused that motor sometime in my novice-ness (15, 13 min runs in a row probably didn't help) Maybe the motor going out one day was my fault...LOL

Sorry, I don't remember these kinda things....

I'll be racing primarily outdoor for a while....what would be a good rollout for those conditions? I'm smooth yet agressive...lets try some middle of the road settings

You'll have to play around with gearing at the track but for a medium-small I'd start with a (23-25) and for a large track I'd start with a (26-30+) rollout. Always try a low rollout and then add teeth to the pinion one at a time. Run half a pack through practice at race pace and then pull over to check motor temp to make sure you motor isn't too hot. As long as your motor is kept in good condition it shouldn't come off screaming hot after a run(medium-hot is fine).

I run red/green springs and 767's. If you find you really have crap all torque on the medium-small track you could try dropping a red spring on the neg instead of green or a purple+/red- combo. For large tracks(flowing) rpm rules so a red/green or red/red combo may work better then the purple/red.

JDXray - Those (23-25) and (26-30) were rollouts not pinion gears. Run in your motor at 2-3v till both brushes have wear across the full face of the brush.
