Somtimes when I am driving my firestorm and I hit full throttle it starts having very little power and almost stops the engine, what should I do? And the other day it was about 15 feet from me and it took off and I could not stop it. Does that meen I need a new receiver? Thanks for all the help[8D]

Sounds like your tune is off. As far as the runaway you need to get a failsafe as well as check all your connections and make sure your crystal is in tight. Make sure you batteries are good and if you co not have one get a good receiver pack.
