Red springs allow the Monster stock to rev a bit more which is better on a longer track where top end is more of a concern.

If you WANT to use Purple springs on your Monster Stocks, go right ahead. It's just too bad we don't race at the same track!

Default Shimming

n00b question: I just cut the comms on two montser stock motors. What is the proper way to shim the armature? How much total end play should I have and should it be divided evenly?

Thanks,
John

Jcrouse.The common process is to take all the shims out and turn the motor to it's side.Brushes and Springs are NOT IN at this time.You then spin the arm and see where it centers up.After spinning it pull the arm down and measure the play in it.Spin it again and push the arm up in the can measuring the up travel and shim accordingly.This centers the arm in the magnetic field of THAT particular motor being they are all different.
Goodluck with the motors and if racing have fun.

P2k2 is a nice motor.If it's a pro version it will have trinity"e" brushes in it.This is a good all around motor.If you have BIG LONG straights then it may get beat top speed wise by a couple of other motor's out there.But the P2K2 is a great all around motor and nice for smaller to mid sized tracks.If your new to electric I would just keep running the motor and find someone to cut the comm on it for you about every 6-8 runs.This keeps the motor fresh and cutting it this early or skimming the comm will actually make the motor last longer than running it soo much it gets a deep pit in the arm making you take MORE off when cutting it.I would replace the brushes when they get discolored,burnt or noticable wear.
Goodluck.

Centered as 'TexRacer' stated. You want approximately .004-.005" on EACH side for a total of .008-.010". Any less and the Motor will lose Rpm, any more and the Brushes will unseat when the Arm moves around. After you've done it a few times, you can tell by feel if it is right.

For maximum power in an Epic (Trinity) Motor, try some Putnam Brushes. Trinity Red/Green or Red/Red Spring combination. The P2K(2)'s respond well to having the Brushes timed (advanced) cut.

AND, no matter what anyone else says. ANY Motor can be used on any track. You just have to know how to Gear and tune to to overcome a Motors weaknesses.
