What standup brushes and springs do you all run in the 21T spec motors? I'll be running the ARCOR Super Spec which is spec motor w/ any standup full faced brushes (no cuts or holes...serrations ok), any springs, and any 3800 mah or less battery. Thanks!

some of the local guys up here are having good luck with the F Brush along with the 4383 is always a good choice...............

Shoot me an email if you need some and I also have some killer JBR Cells to offer for that class as well..................

And where will you be racing I will be racing this summer in NC and SC.......

Lightspeed 4000,and Orion red,silver,or black springs.

As far as longevity / good pwr we run the 4383 as it draws 3-3.5 amps at 2 volts with a fan .
I know this sounds mild for a race motor but this motor has only 12 degree's of timing.
Thats with a red trinity spring , never tryed the f-brush so really can't say how they compare.

Hope this helps

My best spec motors pull 4-4.5 amps at two volts with a fan,this is with 4383's putnam greens can go even better than that.

If we didn't mandate a red spring , I'm sure we could get a better amp draw.

I personally like a purple or silver on our "hot" stk or 19 motors.

Our motors all go into a mixed pool every week so its luck of the draw to get a better one, no one takes the motor home :thumbsup:
