What will be a decent starting point for rubber tire 13.5 racing? I'm running 48 pitch with the stock 87t spur.

Thanks

Carpet or asphalt? Foam or rubber?

Something around a 78 tooth spur will be needed to fit a large enough pinion on the TC5 for 13.5 racing...If you are using a 78t, somewhere around a 31-35 tooth pinion is in the ballpark depending on the size of the track.

For gearing, I use between a 96 and 108 spur, and pinions ranging from 30-45 (64 pitch) with my 13.5 setup.

I'm using a 100 tooth spur and 47 tooth pinion, but we have two 90' straights.

On my car I use 48p gears with a 72 spur, and 35 pin, but that is with foam's. So for a rubber tire car I would start with a 75 - 78t spur, and then have 31-35t pin for starting gearing.

I have a mamba 7700 with a reedy lipo 5000 7.4v I was running last weekend and my temps on the motor were around 170 is that normal. My Spur gear is an 87 tooth and my pinion gear is 22.

Just looking for experience w/ certain equipment:

The new LRP 13.5 BL Motors - Any Good? Better, Worse than Novak?

Reedy Lipos - Better, Worse than Trak Power?

Thanks!

Thats a little on the warm side but its fine. You may want ot drop a tooth or go down on the ESC timing a setting.

Were you just running that or actually racing at that 8/1 ratio? Reason I ask is the ESC on the Mambas will often run hotter then the motors. 170 is fine for a MM motor, but my guess is a mod race at 8 to 1 you'll overheat. I'd go 9.0 or higher (87 / 19) and timing set to lowest and not to steep on the drag brake to keep heat down. Temp both speed control and motor and adjust as needed. The Mamba tolerates heat well, 190 on ESC at race end is no big deal.

I agree, they can really take the heat. I have the 7700 set-up in mj BJ4-WE, and I have gotten the motor up to 225-230*F, and the ESC up to around 205*F and both still work just fine (although I should put a smaller motor in that car as that is a lot of power for a off-raod car).
