just like to ask if you have had any crashes with your hyper 7`s.
i had one before, i was driving along and the throttle got stuck in full throttle and when zooming off towards a busy main road by lucky it hit a curb and then hit a grit bin and cut out. and all the damage was a bend drive shaft and lost my air filter. i was so shocked on how tough the hyper 7`s are.
so your crashes.
