Pesonally, I use the mm and a feigao 12s 3000kv motor on 3s in my pede. If you are doing 4wd, crt.5 or similar size/weight, a mm with a feigao 10l on 4s or a 9l/8l on 3s would be the ticket for a low cost good performing system. The mm controller may run the vxl motor too, should have similar performance to my 12s feigao. I run a 45/15 geaing which is similar to 23/83 gearing. I am guessing you have a rustler, that gearing would be too much in a pede with the larger tires.
I have a Mamba Max system, and I really like the ESC. I was wondering if anyone has ever ran the VXL motor off the Mamba ESC. I'm thinking about doing it when I finally get my Rusty running good.
