Help with P2K pro stocker...

[Car_Head12]

Mine is in the mail so i dont want to be clueless when it arrives, so a couple Q's.i have a regular non-rebuildable stock motor so i have no idea what the springs etc. do (?) what type of maintanence will it need? also i know there is a big debate on how to brake motors in but which way would you do it...

thanks

If your saying the P2K isn't rebuildable your wrong.

tc3guy, read what he said again, I think you are the mistaken one here ;-) his current motor isn't rebuildable, but his new P2K is in the mail on its way and he is asking for general knowledge from the motor junkies.

car_head, The P2k is a nice motor, the brush springs simply push the brush to the comm. Maintenance is pretty straightforward. You don't really need to touch the springs unless you get into tuning, but the brushes should be replaced depending on how you drive. I usually do mine every 10 runs, and always cut the comm with the brush change. sometimes I go longer than that, sometimes shorter when I race the car. I am not a motorjunkie so this is how I take care of mine, it may not be the best way so someone else add info for me. As far as breaking the motor in, I don't really do anything special, just put it in the car, run it easy a few packs then tear it up. some dip it in water and drive it with four cells for like 30 seconds, others do the same dry. I'm really not the best one to answer this, but I see I'm the first to repsond. If I'm wrong here, someone tell me, I want to know all as well.

thanx, i appreciate the support

Good motor choice. The P2K pro is already run in & needs little if any break in., I'd just run it easy for about 1/2 pack & then go have at it. The only thing you need to do initially is to keep an eye on the temperature. The P2K is a very high torque motor, but you still have to keep gearing in the right range. What kind of car or truck do you have? You didn't say what motor you were running or what your gearing was before. Let us know & we can probably get you close to the right gearing.

my new xxx is coming in the mail, and im gonna be using it on that, so what pinion should i get?
jus for fun my setup is gonna be:
JR XR2
MC330CR
P2K pro
high tork, metal gear (that is key!), servo

im not gonna need anything else right...

XXX + P2K gearing, 84/23x2.41=8.80 final
As far as servos go, I highly recomend the JR4750. Don't let it's conservative numbers fool you though, it's very fast in driving conditions. The Airtronics 257 or 357 is also a good choice. The 257 has been discontinued, & the 357 has more torque. You don't need a tremendous amount of torque for a buggy though. Whatever you buy make sure it's coreless. If it's not coreless the speed rating numbers won't mean a thing. This is due to std servo motors inability to change directions rapidly, as in when you make quick steering adjustments. Coreless motors rotational mass is next to nothing, and can change direction instantly. Have fun with your new car! :cool:

so what pinion should i get...?? :rolleyes:

[Car_Head12]

ahh i see i mossed that part... (stupid me)
its 23tooth!! yehawww!
thanks! and im sure ill have TONS of fun

The 23 in Railman’s equation above is the pinion. Use a 23 tooth pinion to start.

I’ve got to learn to either type faster or refresh the page before I post. Glad you figured it out.

You're right. 48 pitch.
