Mad Bull pinion

[whahooo]

Hello, i changed a Fighter Buggy RX Info an Mad Bull.

 

I did't Changed the pinion. The Car accalerates slow and the Motor seems to bei under a Lot of load and Males morgen Boise than before.

 

Should i change the pinion or should i Install a tourque or Sport tuned Motor?

You could change the pinion, or go brushless. They are a lot torquier than their brushed equivalents.

+1 for brushless. I had a goolrc 9T in my fighter buggy and it was a blast to drive. later the same

combo was ok on a Lunchbox with the Grasshopper pinion and it did run great. 
 

both on nimh or 3s lipo

I always thought that you need Kipos for brushless, so i never concidered that.

i run brushed motors and NiMhs in all my cars.

 

So the pinion route is my choice, i think.

Maybe i install a hotter motor to the lower pinion.

Not necessarily.

Brushless with NIMH is better than brushed with NIMH. Brushless are technically more efficient all else being equal so I don't see why NIMH is inherently less suited to brushless than it is brushed. You'll get more out a of NIMH + brushless than you will a brushed + lipo.

I would say it goes in this order from "worst" to "best"

NIMH + brushed
lipo + brushed
NIMH + brushless
Lipo + brushless

That's assuming motors of similar specs. A brushless motor will generally draw less current than a brushed motor of similar power although it's worth bearing in mind that the typical 1/10 brushless motor is 3300-4000KV which is in the ballpark or a 15t brushed motor so some of that efficiency tends to have been traded for RPM.

Lipo will always beat NIMH but that's the same regardless of motor type, it doesn't mean you can't get some of the benefits of brushless whilst staying with NIMH.
