Arrma .8 Mod Pinion Work for us?

[Snaab9-2]

I was looking for a .8 mod pinion for my Raider that wasn’t over priced (32 pitch would probably work but was being OCD). This Arrma pinion looks like it could be perfect.

Does this look like it would fit a normal 540 motor? I just know nothing about Arrma.

The model it's listed for uses a 5mm shaft motor. If that is correct, the answer is no.

Might be best to contact them directly. It could be 1/8", 5mm, or 5mm with a 1/8" sleeve. All are common enough.

If all you can find are 5mm pinions, the reducer sleeves are available separately, for ~$4-5.

Thanks guys! Maybe this one will work? What diameter should I look for? 3.2 mm?

The stock pinion isn’t that expensive..

I was not looking for stock nor one made out of soap……

Ok. You didn’t mention that..just trying to help. How about the W-5085?

You are right, I didn't say in the post I was looking for an 18 tooth! It was only in the links.

Thanks for trying to help. I ordered the Red Cat one from Amazon and will let folks know if it works/seems like it is decent quality (It seems like it should fit the motor shaft). I saw an 18t Kyosho pinion on Ebay but it is aluminum (at about $15 SHIPIPED) and I am not so sure it will hold up to my brushless setup (my 37 mph+ Raider that is getting ready to be just shy of a 40 mph car lol)! She is a ripper!

I am going to go back to a stock sized rim and see if it helps lower the center of gravity a touch to make it more stable under braking (my cheap ESC/motor combo doesn't have any modulation for the brakes.... all or nothing at either 25, 50, 75, or 100% power.... and 25% is sill too much).

I have a few videos on it running brushless but here is one with it running on a half charged LIPO https://www.youtube.com/watch?v=lF127bHUUDs&feature=youtu.be
