I have an HPI RTR 3 and I want to sell it so bad right now but the only thing holding me back is the fact that I got a 12RSS engine for it. I am just going to buy a starter box for it and that is it. If I don't see some huge power out of this engine IT IS GOING UP FOR SALE !!I tried to do as much as I could do to it. I put in a 2 speed tranny with a lightened flywheel, racing clutch, thicker aluminum chassis and it always seems to load up but never has real power. Can someone please help me with some tips to make this run B'tchen?I really just want to trade it or sell it for a NTC3, OFNA Nitro Sedan or a MSX3 3. HELP ME!!!!:help: :flaming: :censored: 8-0
