have to admit, I love my tekno lektron 2200kv with my MMPro. super smooth and can handle 2 - 2s 5000mah turnigy's no problem. I read alot about sensorless motors being jittery, but I think thats old news. especially with the MMPro.
It does need a little modding on install though. but if I can do it...
...plus, I would rather have more motor and less battery than the other way around. my two cents. and you can always tame your beast with some MMPRO programming! (if I bust one more diff its going to %50 punch damnit!!)
I briefly considered a MM 2650 combo but figured it may kill my truck with stock diffs and axles; I've got steel centers though.
Both of those motors will run very well. The aquacraft will be a bit more tame.
You CAN get big 4 pole sensored from the 1/8 tekin line, but the price is horrific
