The guy just whants to make his sv as fast as possible and doesn't whant to have to be limited to 1 or 2 passes. He just whants to be able to run allmost to fast for the sv and run the whole battery packs down w/o overheating his packs or esc. He doesn't whant to spend more than a feigao or maybe ammo costs. I don't think he's actually going to be racing it. I told him if he really whanted to run saw he'd only be getting a couple minuites before heat becomes an issue and he doesn't whant to have to come in and cool off after every couple passes, so I think he really just whants to make it a very fast sport boat. What motor would be pushing the envalope in that price range and would be safe with the 120 amp esc he's allready got?
