hehe, yea I agree notice that when I posted my numbers all I was trying to illustrate was that they got much better than "out of the box" ...and in fact I said

alline the brush hoods, seat the bushings and break them in w something, metal polish toothpaste or trinitys bushing break in, center the arm and shim it so there is a little lash in the motor

BJ has made references to 100W at 20A. and @28A mid 120's.


Being 11pts off at 20A and 5pts at 28A is workable. We have only had these motors for a week.

What is your hot setup for a P2K2?
Well sorry, I didn't mean to insult your motor tuning expertise Just that an 11 percent difference is huge...I can feel a 5 percent difference with my P2K's. I'm just surprised...Maybe you got a bad motor...

No insult taken. You seem to pass along a lot of learned information. What is the hot setup there Speedo for the P2K2?

What are your motors turning?

I wish I had a dyno so I could race my motor numbers too
Need I say it, You Know I'm joking!

I'm being different and running an MVP, problem is there's no fast stock guys here to compare it to.

Anyone think a final drive ratio of 6.35 might be a bit high for a 4 minute race? I've done all the break in and brush tuning things, so it's running well under melting point ..

Hey I have a P2k Pro and it has about 5 packs through it, most slow, only 2 on a practice day at a race track. I dont have a good comm lathe and im planning on racing on Saturday if it doesnt rain. Night race. First 'real' race and even though its novice, how much longer (# of packs, its a 1/12 with 6 cells @ 2000mah) should i go untill i try to find someone that would cut my comm at the track, if it needs it. I probably wont be around to racing till the new year sometime and during that time i could probably save up for a Hudy or something but im out of luck here.
I looked at the brushes and they werent discolored or anything BUT the serrations im estimating here, are maybe about half the original depth.

O wow. hehe

Uhm, theyre just the stock brushes and stock springs, im not sure about the brushes but the springs are just black (-) and red (+)

Its the exact stuff that came on the motor, its brand new besides the runs on it, nothings been changed.

Maybe i should put some lighter springs on it when its time to rebuild (soon). Maybe a lil more rpm's which is always helpful in 1/12 and theyre so light even if it takes some torq away, i already didnt need as much as it was giving me for my driving skill so far.
Any good moderatley high RPM preferably long lasting brush/spring combo's would be appreciated for the original p2k Pro. Im new to actaully trying to tune the motors in particular with different things and some advice for that would be helpful.
