RE: U Can Do 46 or Global Freestyle?
I had both and all the comments already made are valid.
Don't put a .46 in the Freestyle if you want to 3D.
If you want a relaxing plane to fly in slow and close the UCD is better, lighter wing loading and a larger plane. The freestyle will drop a wing a little faster than the UCD.
The Freestyle does KE better unless you mix out all the coupling in the UCD.
