+1... what's happening is when you have your radio turned on, the servo holds the carb open just enough. this is due to your trim setting. the zero point pulls the carb open just enough. when you hit the brakes, the servo is closing the carb too far and causing your engine to die. to stop this, you must turn the idle screw in to create a bigger idle gap. this way, the carb stays open as much as it needs to properly idle regardless of servo position.
