RE: HYPE 3D OR BOSSANOVA?
For 3D the Hype 3D hands down.
It is a fantastic 3D plane. Light and very tricky. Power it with a West 50 with the pipe or a YS 63 or a Satio 82 would be insane.
The Balsanova is good if you want a faster flying airplane, it is not a 3D plane.
If you want to split the difference between the two, the new Filton Inspire 60 looks to be the badest purpose built 3D plane in a long while.
If you could get a Madness 2, I would buy that over the Hype.
