Well I'm having a hard time finding the manuals, but i will keep searching for yah, and no, i have a t-maxx, the race guard i have is made by dynamite, it is currently fried but i remember reading some of the manual, just trying to find it right now to kinda re-cap...
I found this, hope it helps! :Race Guard protects nitro racers from the hazards of signal loss and battery failure, and now it's available for the popular Airtronics M8 racing system. The Dynamite Race Guard Fail-Safe plugs in between the throttle servo and the receiver and monitors the radio signal and voltage. If interferences occurs or the battery gets low, Race Guard kicks in, moving the throttle servo to a preset position (normally full brakes) and holds that position until the problem is resolved. To set up Race Guard, just hold the throttle at the position where you want it to go if interference occurs, then push the button on the radio guard. Dynamite's Race Guard is great for boats too.
So i was correct, you want to apply the breaks to where you want the race guard to apply them when it is activated, to program it, apply the breaks to that point, then hold down the button, you should have a green light if it is ready to go, green-normal, orange-brake set, red-signal loss, flash-low battery...
