I knew Saito engines were good, but wow- glad I didn't try one of those the first time! Thanks for the input and I will keep watchin to see if anyone else steps up with some options.. I would really like to go with a gasoline engine and hopefully someone else has too. I know the Zenoah's are good but just wondering if any others fly that plane well, it's a beautiful airplane. I have watched the other guys who have them fly and they both have the red one's and mine is blue can't wait till spring. I live in Michigan so it will be a great winter project.
