had that happen with nitro, but in my case the traxxas TQI AM radio I had was malfunctioning... The reverse switch would reverse at random... caused me to go full throttle into my house.
Then my nephews stampedes TQI radio failed after that(steering wouldn't work) causing him to break an A-arm...
Best one after that I bought a fail safe(from Venom RC... ) after a week that thing caused me to lose control of my trucks throttle, and made it go full throttle I'm glad I still had steering control cause I caused it to flip so the engine would die out. Funny thing is I tested it everytime I used it prior to running to make sure it was set properly, and the failsafe failed me...
Was so happy when 2.4ghz radios came down in price moved all my RC's over, and best one it even has a failsafe built in so no more mishaps as I've not lost control once since I moved over even after the RC drives off the horizon
