well all I can say is that I have 4 speeds 1 modded 3 stock
the modded one in my truggy gets 13.9 the rest get 8 they
are all fast but for me I like run time I will be getting the other
three done soon like Frank said one less pit stop that is like a
free 15sec on the field that maybe the diff in first or second add
a fuel gun in to the mix and it's more yet
I need all the help that I can get
so mod them if you got them
