I tried to do backflips with my firestorm on a 4 foot high jump,but without success. I landed upside down and didn't break anything, but my throttle/brake servo quit working,which started the thread called(No throttle response.).....Its almost impossible doing backflips with 2 wheel drive stadium trucks[:@]The 4 wheel drive monster trucks do backflips with ease..Is it because its 4 wheel drive or is it just all in my head?
