Help my car is slow!!!

[chrisbryan800]

I've been buying up all I can to get started in 1/10th off road racing, and thought i'd made some good purchases in order to be reasonably competitive, but my car seems slow and i'm not sure why. Any ideas??

I have a rc10 b3 with stealth transmission and general upgrades. But ultimately i'm running it with a Reedy Mr 10x1 and a Novak Dually Speed Control. The gears are 81 tooth spur and 23 tooth pinion. I'm using 4200nimh's and the car seems slow like an old tamiya running a 540 stock motor. Am I missing something obvious here?

Are you sure the ESC is reaching the limits? I guess the lights should change when they reach full power, maybe it just needs setting up again.
as for the 10x1 - a very fast motor and just about quicker than I've ever raced with in 2WD. Perhaps it needs skim / brushes? a 19turn can be pretty decent in 2WD so a 10x1 should be very nippy.
Another thing could be your wiring, what connectors etc are you using.

Cheers Jimmy, I suppose I could reset the esc, it's the one touch setup version so I figured pretty fool-proof even for the likes of me. On the wiring front, I did have to solder some wire together to get the esc postive to reach both the motor and battery pack. As for connections i'm using corrally male-female types!

I think the job is reasonably neat, although i'm no expert, and would this cause enough of a problem to make the car that slow?

The pinion might be a touch too big?

Nah, pinion wont make that much difference. slipper not slipping is it?

Try that, if no luck take motor out and put it accross the cells, see if it spins up properly. Just do it once though, there is the slight chance you can throw winds doing this.

Sorry to sound stupid, but how do I check the slipper clutch? Anyone have instructions?
