Hi Guys, What engine do you recommend for a Great Planes Pitts 68" span? I"m thinking about a Zenoah 38. I"ve seen several in High Flight mag. with them on the Pitts. I Have a Fuji 50eis on another plane{Reawwind Speedster} What about a DA 50? I feel like a mag. engine like the Zenoah eliminates the need for extra battery. ANY INPUT WILL BE GREATLY APPRECIATED. THANKS. flying viking
