i agree with the engine weight aspect, but the power to weight ratio of the zenoah i am just not a huge fan of, plus its a house to put into anything with a smaller cowl. I much rather put a 80/85cc in something with the same weight as the g62. Currently on the drawing board are a Ziroli 101" b25(pops) and a Top Flite gs p51(me) and two little TF p40s(joint build). next are Ziroli p40(me) and Ziroli Zero(pops).
