My current fastest boat with the 29.5cc fully modded Gizmo Zenoah and Hanson pipe she really roars around the course. It hit the bank a couple of times with her when getting some experience steering hence the yellow bow with flames etc. I'm getting to be very experienced at fiberglassing boats!!
I converted this MVD with a Vertex .21 and trimmed the fat to make it faster and was fun but too many boats so she's off. I have about 20 rc boats all up!
My current list is the Falcon cat with zenoah 7hp from Gizmo and a hanson stinger pipe, Delta Force 45 (35.4") with (just removed) NEU motor and ETTI ESC that I'm replacing with a CMB 4.5 HP .45 Nitro and CMB tuned pipe, Promise Hobby Lynx 47" with a stock Zenoah 26 and tuned pipe...
