I am building the ARF Christen Eagle from Great Planes. I am looking to see what anyone has put or is putting into their Christen Eagle for power. I read an article in Model Airplane News and they used a Fuji 50cc. They said it was a perfect match. I have not got into gas engines yet and thought it might be time to start with this one. Please let me know your thoughts. Thank you to all who have something to say on this.
