Hi everyone

I have this HSP 1/10 Storm 2wd SCT that i am trying to upgrade and i am trying to find a spur gear that has less teeth and will fit it.
I do not have much knowledge on how you find a smaller spur gear that will fit your RC car, so it would be great if anyone could link a smaller spur gear or tell me what i need to know to look for one my self. 😀

Cheers
Is yours the one with the slipper, or the pin? If it is the pin style, you are out of luck. They only make 2 spurs that style for HSP cars. The second one you might be able to retrofit one from another vehicle.

Edit: I just looked it up and found that it is the second style. Depending on the diameter of the center hole, an Arrma Fury 32P 54T or 57T spur may work on it. You will need the spur and the pads to match. If your motor has the 5MM shaft, you can get pinions to match the 32P spur. This is the 54T spur: https://www.ebay.com/itm/2746268300...MI7v3c3pSg8wIVjMDICh39ogiwEAQYASABEgLf5_D_BwE
and this is the 57T spur: https://www.ebay.com/itm/362504971256?epid=1668399450&hash=item5466fae3f8:g:NE4AAOSwrdVfUN-Q
and these are the slipper pads that match either spur gear: https://www.arrma-rc.com/part/AR310584

You said spur gear then later said pinion. The pinion is on the motor shaft. The spur is the bigger one driven by the pinion. Which one are you looking for bud?

If it is the pinion, this should be the gear specs you need:
48dp pitch
Your motor shaft diameter should be 1/8" or 3.175mm.

Without knowing what size pinion you have, we can't recommend a smaller one. But you can count the teeth on yours and look here...

Thanks so much for the help everyone! 😀
Definitely will check those links out!
I am going to put a TP 3080kv 4s 36mm by 84mm motor in it and a Castle Mamba Monster x 8s in it to suit with a gear ratio of 1:200!
I can't WAIT FOR IT TO GO TO THE MOON!!!!!!
I might be able to film it and post it here if you guys want but until the batteries turn up i can't :(

Cheers,
