RE: Engine for Funtana X50
Why would you think they are tail heavy? My X50 has a 15.5oz webra 50 in it, balances perfect, battery behind the fuel tank. A 25+ oz 91 would be way noseheavy, and plain heavy overall. Put any good 50size two stroke and a tuned muffler and performance will be good. I tried a saito 82 and 14-6APC, and went back to the webra.
