SPEED RUN LOSI NASCAR HOTRACING 57 SPUR/22 TOOTH PINION!50+

Changed out the stock spur to see if we gain any more with a 22 tooth pinion. Not sure yet if the 57 helps or hinders it. Maybe if I had a bigger pinion that 57 would benefit. We only gained 2-3mph.Still need to do more testing. Also added the vitavon bell crank that I took off mojave grom due to binding with arms.so far the steering is holding up but these groms have a major weak point in the steering.

These NASCAR cars, seems to always get 2-3mph more than the Groms with the same kits, I started my groms with this same kit and it was very cool, but now I moved to Castle Combos, and it’s crazy, really good video, specially the 57/22 combo 👍

I'm going almost 30mph with the stock motor with a 57 spur gear and a 20t pinion 😮😁👍

For what it's worth, I'm hitting 47 on 2s with a castle 0808 8200kv, and a 17tooth pinion, stock spur.

How did you fit those foams on it?

[@RCRICHIE]

@@Nobz619 cheapest way is replacing hexes to mojave grom..$11 or if u want all metal from arrma..30 or other brands

[@RCRICHIE]

30mm foams depending on truing will rub,i have gorilla tape underneath to protect. 26mm will fit all day no issues..harder the better I think(shore)
