What's the most capable .60 3D arf?
hmmm...
60 - 80" and a .60 size motor?.... Nope!
My 64" Edge flys with a .61, but no vertical or hover... Needs at least .90 2c.
I can't imagine too many 60 - 80" wingspan birds that hover with a .60 size motor sorry.
You'd need to be around 40-45" for hover with a .60 IMO
