Made this specifically to hop up the Ehawkeye by Hitec with a drone motor but it could likely be used on other stuff. If you happen to have an Ehawkeye simply unbolt the factory motor with 1 screw and this will slide into the existing motor mount inside the nose. I would say print this in ABS or anything other higher temp material depending on how hard you plan on pushing the plane. We have these things going 80 plus and some over 100 on 4s so they get a bit hot
