mtronics pro and mambamax 5700 ?

[Rtsbasic]

I wouldn't chance the MM in really wet conditions, theres a difference between water resistance and waterproof...

The Mtroniks will handle the 5700 fine, and as you are aware is completely sealed and waterproof. Mtroniks normally sell it with a "real" 540 size 5900kv motor, so the 5700 will be less work. If it was more adjustable, USB programmable and they used better quality fets it would be a better controller than the Mamba. Still a very good controller though, I've had one for 16 months now still works fine. Been through plenty of crap weather, snow etc.
