RE: looking for a good 40 size 3d plane
You want a profile.
There is not a glow plane in that size range that will perform like a profile. If you want looks, do a fuse plane, you want to learn 3D and hover, profile.
It is all about weight, the profiles may be up to 2 pounds lighter.
Almost any of them. I see you are in the land down under, the PA Bad Boy is made there and a good plane. If you want a kit, contact Paul Swany and have him ship you a Mojo 40.
