Mark, would it be fine for me to turn my 7.5 motor down until its the speed of a 17.5 so i can try the stock class. Otherwise ill just get a 17.5 motor just to try it. I have heard stock is fun and itd be pretty cool to run it.
Also, PM me on how much you can get me a Futaba 4PKS-R for.
Thanks,
Gio
