I have the 66" Edge with a Saito .91 on the front. It has good vertical, not unlimited, a nice strong climb. The control surfaces are kind of small for any 3d, outside of hovering.... It's a little tail heavy with the Saito, so the Super Tigre should be about right on the front... If I get the 56" Extra (I'm thinking about it), I will use a Saito .91 on the front of it.. mounted inverted... I have flown the VF Sukhoi, Edge, and big Extra... All good sport fliers, and very well built...
