need some advice for a futue bl project..

[t-maxxracer32]

well i am fine with those speeds. anywhere in the 40s is cool.

now to esc... between the 80b and the mm which one would be more suitable? will i need a bec with either one? (probably will need one for the mm but not sure...)

so pretty much for the extra money the xxl is def worth it? i dont wanna be spending an extra 150 or w/e for nothing uk?

would like the motor i get to be efficient... little cogging... long runtimes... and for it to stay farely cool.
