mm on 4s question
 

I'm getting ready to buy a new mamba max control and try it out on 4s. I know the older mm's armed and ran worked good on 4s but what about a new one?

It'll run fine on 4s, just remember to disable the bec and run a ubec and you should be fine.

Ok, thanks guy. I just ordered an mm/cooling fan/and dimension bec.

Cool, good luck!
