I just bought my New Ofna Ultra LX One the other day. It has a pull start on it and it SUCKS. I need to get a Roto start conversion kit for it. It has the Force .28 motor in it. I don't know where to get one and where to start looking. Any help would be great. also What is a good setting for the stock shocks and shock oil weight to use? Any other things would be great.
