I made the mistake of purchasing an edf instead of a prop to build my first plane. I have made several planes using a 50 mm edf, most of them lack a proper airfoil and are quite fragile. I got lucky with my first flight but I soon realized that having a highspeed plane is not very ideal. Does any one know of a plane that can perform better at low speeds and uses a 50mm edf? I have found some planes that would be suitable but they do not have any plans. I'm sure someone will tell me to search the forums and the flite test page but, I promise you that is exactly what I have been doing.
