Hyper 7 SPUR GEAR HELP

[Pes307]

Hi, I've recently shredded my two gears that make my nitro car move. I think they're called the spur gears and the pinion. What are the best sort of cogs to buy for it? Thanks.

To be honest, just get the stock ones- with whatever the stock ratio was (13t/46t)
If you do want to change then the bigger the PINION gear (smaller gear) the less revolutions it has to make to turn the SPUR gear, thus a higher top speed and less torque. Whereas if you have a SMALLER PINION gear, and a larger SPUR gear, you will have a lower top speed but much more torque- for example, rock crawlers have a SMALLER PINION gear, and a larger SPUR gear, they don't go very fast, but they can go anywhere. If your still stuck here's a page on the forum that'll help:

How did you shred BOTH? Usually the spur goes as the sacrificial piece.
