whats a good stock racing motor?

[racin4ever]

i have a P2K and im not doin to good in the racing, last sunday i got 5 in the Main B race. is there better motors out there?? what do u think is the best?? :confused: :eek:

As long as your motor's comm is in good shape, and you have new/good condition brushes installed, a stock motor is pretty much a stock motor. The difference between a really good one a a bad one is not too much.

Stock racing is all about batteries. Check out some good 2400's from Superior Matching Concept, www.smc-racing.com. (http://www.smc-racing.com.)

Good luck.

sirspeedy,
yeah i got it used so i might need new brushes. i havent check the comm. so i think im goin to do that, thanx.

is the Trinity P2K stock motor pretty good though?? is there a better motor i can get that will last longer or anything?

I have a P2K and a MVP. The P2K seems faster.

I have a Green Machine and it is pretty good. But they are right, a stock motor is a stock motor.

[racin4ever]

arent they all 27 turn singles??? with laydown brushes?

[Grizzbob]

Well, there are notable differences between them, but if set up & geared properly, then all will be very effective & run quite similarly. But, you do need to maintain it properly or else it will slow down considerably & other, better cared-for motors will then outrun it..... :)

allright i see now, so i should probably clean it after every use?? what should i use for that? should i get the comm drops??

[Grizzbob]

Well, for cleaning it between runs, its a good idea to have a comm stick(there are a few of them available, I prefer one by Edge products, it looks like a pencil eraser, just pull a brush out of the hood, insert the stick, & turn the motor's output shaft while applying light pressure on the stick to clean the comm) & to use motor spray to rinse out the gunk that always builds up. Additionaly, it's a very good idea to rebuild the motor every 6-12 runs or so(definitely no more runs than that, the comm wears down faster & faster the more times you run it between rebuilds) & have the comm retrued & replace the brushes. As for comm drops, some people swear by them, but I really haven't noticed enough of an advantage to be worth my while, especially since comm drops wear off long before a run is over, & they all have a tendency to attract more dirt, which will only make them wear down faster. The only time I use drops is when I'm breaking in a pair of brushes in the motor(I use a drop on each brush, run the motor off a 4 cell pack with no load for about a minute, & then spray it out to clear away the gunk). I much prefer to get the motor to be strong without the need for drops, & set up right they'll stay very strong all the way through a run..... :)

Listen to Grizz, He's on the money!

[racin4ever]

thanx grizzbob, ill try to do that, i need some more money to by that kind of stuff, i appreciate ur help, thanx a lot :D :)

I've got afreind with an e-maxx and it runs on 550's and those realy good, of course it depends if you have an off or on road 550's work great in off roads speed gems are the choice for onroad. :)

[tc3guy]

550's arent legal for racing do you should stick with 540's. Most cars arent large enough to fit a 550 in them.

[racin4ever]

yeah i am so gettin an e-maxx when i get some money! :D

[internetspy]

i have heard people have actuall luck with the green machine 3 but i bought it brand new a while back. i poped it in and took off about 2 laps around the track 32$ down the drain it burnt it up with a 18 tooth pinion... but luckly i had a freind with me and he gave me a chrome stock rs which i love to death so there is my 2 cents :p

[Interceptor]

If it hasn't been said already, se if someone at your track will cut the comm for you when you install new brushes.

I have a GM3 and I absolutely love it. it is very smooth. I had a P2k and it was good also, but the GM3 seems smoother and faster.

[racin4ever]

thanx all, but i have a stock motor that some one made and my friend gave it to me, i put some motor cleaner in it while it was running and it is doing good, so im goin to stick with that and my P2K, but i need a mod for jumps and just for fun, so i need to look, any suggestions?? :p

[ttweedle]

I got a P2K pro, ran it about 10-12 times now the brushes grooves have worn off...Is it time to replace them? LHS owner said that they were just getting broke in...Sounds kinda off to me, but since I don't know can someone on here tell me whats right. I don't have a lathe, although I would like one. btw the comm looks good, no scorch marks of any kind. Do I have to true the comm every time I change the brushes? How thick is the comm anyway...Im a machinist by trade so I know all about Truing the comm, how many times can you True it and it still be usable.

Yes, it's a good idea to change brushes everytime you true the comm, & visa versa(though if the brushes haven't burned, then it is possible to reuse them, as long as there's enough of the brush left). If you don't true the comm when you install new brushes, your comm will wear down even faster than normal from the brushes bouncing on the comm surface. As for how many cuts you can do, it depends on the comm's diameter when you start out & how much wear you're dealing with. Many stocks start out with a comm diameter of around .295 in., & from there it should be fine until you get under .270 in.(after that, you risk it tearing apart, either in use or on a lathe, at that point there's almost no copper left on it). Also, when you get it down that far, further retrueing doesn'y really help you much, because the arm loses it's ability to make good power when the comm's too small(also related to not having enough copper left, less copper, more resistance, less power)..... :)
