I had a Vario Bezine Aerobatics some years ago. I do agree that they are as well engineered as some others I have had in the past. But I still predered my Predator overall. It was also very stable in any winds and was easy to set up at lower head speeds for more sports type of flying.

The Predator was a lot lighter (about 4.5 lbs), so it was a lot better 3D bird. Also, due to its lighter weight, it was much better in the auto using the same blades.

My Aerobatic was consequently modified and mounted into a scale Varo H500 fuselagey where its flying characteristics seemed better suited.

That is probably why Vario and their derivatives offer so much scale options and seem to specialize there.
