Lots of places have them. I didn't find them listed for the Wraith, I just looked for the teeth & pitch I wanted. I bought the Traxxas #3957 spur gear 56T, 32P and the Robinson Racing #1714 pinion 14T, 32P.

Alright Harley, your wealth of knowledge is incredible......I purchase a wraih RTR about a month ago. On day one I smoked the 20t motor, now running a 27t from axial as a replacement. But that one is probably going to be short lived.


I'm looking to see what motor can I run on the stock ESC while saving up for the Tekin Pro 3300 combo. Im planning on doing the MMP/Pro4 3300 combo once i have done some necessary upgrades to the axles and gears. Looking for similar speed or a tad bit faster than stock 20t. I usually run a ONYX 2S Lipo. Also, suggested gearing for this?

your not gonna find a 32p spur made just for the wraith so i would suggest using this one

You aren't going to get faster until you go brushless. I would suggest keeping with a 27t and going to 3s.regear a little lower to keep heat down.

The stock ESC can handle that? What gearing? 5.1?

Yes, just add a BEC. Gear in the 5.5:1 range.

Thanks sir

whats the lowest pinion one can use with the 56t 32p spur ? im looking into gearing lower the redline tekin 13.5 with the 12.5mm high torque rotor and mmp i have on the way .

also Harley, could you recommend the settings as im not to keen to destroy the stock transmission instantly. i know i need to change the gears and shafts , but i want to tame it down for starting, then replace stuff as it breaks. im running on 2s .

You should be able to find a 10t pinion and that should fit.

Settings are pretty easy, don't over think them. As for helping the trans, run startup power on low.

I'm getting a Wraith kit soon and I'm tight on funds. Was thinking of using my 15t motor from my Blitz and either the ESC as well or getting a Castle SV3. I'm looking to be somewhere in the middle as far as performance. I wanna be able to crawl but also bash. Just curious if this would be too high of a turn motor or if not, what gearing setup I would need to use.

That motor won't work for long. Read the first page of this thread at the very least.

Didn't think so. Thanks for the info though.

I'm rebuilding my Wraith and just picked up a new Brood 35T. I'm also going with 32p gears. I will be running 3S also. I've never run 32p gears but looking at gear ratios, I was considering 54 or 56/12. Will the 4.5:1 be a good ratio on 3s to keep some wheel speed and still crawl?

27 tooth spur gear on a stock motor. I want to crawl. What pinion?

[Bansh88]

oops. 75 tooth spur

Thats way too small. Get an 87 tooth.

Battery for a stock motor? I'm looking at 2s batteries at Hobby King. 5200 30c OR 5000 2s2p (??) 40c.

I have no idea about batteries. I was told to go for a 2s 5000mah battery. 30-40c. But what is the 2s2p?

Either of those packs would be fine. Go with the cheaper of the two.

The 2s2p stands for 2 cells in parallel and then 2 in series. So there would be a total of 4 cells in that pack even though it's still called a 2 cell. The term 2 cell is referring to the 2 packs in series, therefore 2s.

I just read that a smaller c would be better for crawling? like 15-20?

That's not correct. You don't always need high C ratings but it is not "better" to have low C ratings.
