I watched this .12 JAE boat all runs,both days. Runs on rails,great speed,great turning,very,very nice build,great job guys!We cut half the spray bar halfway out like Glenn does,pipe is get this a Irwin Quiet outboard pipe using a Traxas coupler. Prop we like most is a Lynx cut x442,plain Speedmaster strut turned around backwards and cut off. We have seen 55 and change on radar,it does take a half lap or so to get up but when she goes its worth all the time testing we have spent. Ask Ron Zaker how sweet this boat runs.............. Mike
