Ive never used 3rd channel braking on my RC motos before but I know how it is done from using it on RC nitro cars and trucks with 3 servos..

You will mix the throttle channel and the brake channel so that they are opposite directions. As the throttle channel moves to a slower speed, the braking channel moves towards applying brake. Note that braking channel curve should be something like 0-0-0-25-85, while throtle curve can be linear 0-25-50-75-100, so that braking doesnt initiate until throttle is almost at 5-10%. Basically braking should not be "on" until the throttle is almost off.

Hope this helps!

Nano, also keep in mind that you can add mechanical braking to any RC without a 3rd channel/servo.

Many nitro RC cars and trucks use the throttle servo for braking as well. Look at the Traxxas TMaxx setup (I used to have one) servo pulls carb linkage in one direction, and in opposite direction the servo actuates braking linkage...

Just FYI...

Outstanding! I was in the process of fabricating an entire caliper when I read your post. I definitely don't want to re-invent the wheel and I was happy to find that someone else has done it. Appreciate the quick response.
