I have the Futaba 3PM-Fs which I believe is basically the same radio as what you have except that it is not the 2.4 ghs. I just did a conversion w/ my mbx-5 and am using front brakes on ch.3 and 30% thru the esc. The mech. brake servo will be in ch.3 on receiver, esc ch. 2 steering ch. 1. First thing you need to do is turn on the third ch. The book on that radio can be confusing...it took me quite a while to learn how to use it...don't get discouraged. Once the 3rd. ch. is on you may have to reverse servo direction as I needed to do. With that radio you can reverse any servos direction. IF you plan on using mech. brakes, you CANNOT use reverse. Unfortunately, it is one or the other. Just don't forget to disable reverse in your esc if you use mech. brakes. hope this info helps....
