mamba max pro need info..

[_paralyzed_]

You can use 4s 4500 or 5000mah 30c.

You don't need an external bec. The mamba max pro has one built in. You just plug it into the receiver and go.

The mamba max pro can handle an rc8be, just don't gear for more than 50mph.

For batteries get the largest mah and highest "c" rating you can afford and that will fit.
