Hey Zeb,
Such as? Please give me a few engine choices if you don't mind. I've been flying this engine on my Great Planes Great Big Red Stik. I'm leaning toward a G-38 or 45. Now fella's , before you start replying with !QUOT!Darn, that's over the cc rating of the plane!QUOT!....I do know this, thank you. Now back to my topic.......I have to go and check the weight on this, but I'm thinking, if I am going to spend money on a new engine, then perhaps the DA 50? Now hold on and listen to why.......I 'm thinking maybe I could set the throttle to not go as high and save my airplane from coming apart in the sky? Just a thought everyone, that's all. Is that a major mistake? Another reason, I'll probably want to use the engine on a 50cc size plane in the future or even just sale the engine sense the resale value will hold up better that the Zenoah's.

Ok, nowwwwwwwwwwwww you can reply hahahahaha.............(seriously though, I do appreciate the sharing of ideas and thoughts)
