I'm about to build my X-Crawler and wanted opinions on motors. I'm either going to go with a Single FXR or Sidewinder ESC and want the option on running on 3s Li-Po. Any idea the amp draw on either motor setup??

Thanks Chris

I'd head straight to a handwound 35t...especially if you're going to run the stock 8t pinion.

I used a set of these to replace the axle on our clod based super, and they're geared considerably lower than the clod.

I'm currently running a pair of Holmes Hobby Crawlmaster 1000kv brushless motors on them, each with their own 3s Lipo and Sidewinder ESC. In my opinion, they still need more wheel speed.

novak 55T or integy 45T

We're running a pair of 55t Integy's on 3s and it is quite slow. To do it again I'd run 45t minimum and definitely take a look at 35t if you're used to a crawler with wheelspeed.

I'm trying to stick with one ESC if I go with 35t's I'd need 2 or will a MM work with 2 35t's?

It'll be fine.

My buddy is running 2 HH 35t's on his Sidewinder with no heat or other issues.

55T is too slow so I did rewined to 40T but not fast what I want it..
I think 35T even lower ok because gear 50 to 1
