Sounds like with this engine I can go either way with a 40 or 60 sized plane. I like the looks of the Hobbico Hobbistar 60 ARF, but while reading about it, I read some guys comments that because it wasn't covered in monocote, he would stay away from it even though he really liked the plane. Should I be avoiding some planes because of the type of covering on them, and if so, what coverings should I be avoiding?
