3 CH radio and mecanical breaks

[loa]

Hello,

My Futaba 3PM FASST is on its way to my mailbox, so I'll have a 3 channel radio for my Revo conversion.

State of the Tranny: FOC, hardened pins, 1st gear removed, locked into 2nd gear using the 3 screws method (thanks BrianG and others!).

What I'd like to have: motor reverse (shouldn't be hard with the locked tranny) and mechanical breaks.

Thing is: I've never used a 3 channel radio before, so I don't really know how to handle the 3rd channel, much less how to wire it inside the truck.

Any suggestions?

Thanks a lot!

P.S. esc will be MMM if it matters.
