ax10 deadbolt gearing question

       Remove this ad - become a site supporter!
I bought a castle 3800kv engine for my ax10 deadbolt and I was wondering what spur/pinion gear combo I should run. I am looking at the stock Yeti as the type of performance I am looking for. Also I need to run a size 5mm pinion gear if I am reading the specs right thanks for the help.

Re: ax10 deadbolt gearing question

You're going to need to find a 5mm bore pinion with 48p teeth to run that motor... Not easy to find, but I've done it before. It's easier to convert the spur gear to a 32p tooth size, then you'll have lots of options available for pinions at your LHS. I know for a fact that duratrax part number DTXC9397 will work for you. You'll also get the added benefit of a more reliable, stronger gear set. From there you just need to gear by motor temperature, 160f is around your sweet spot, if temps are too high, go down a tooth or two, too low and you can go up but you don't have to. I'd start around a 4:1 ratio with that motor on 2s, 5:1 on 3s and go from there.
