I agree with Sundevil pilot.... I'm now able to hover and do most 3d maneuvers with it... mine weighs 6.1 lbs sporting a Saito .91.
I can't fly unlimited vertical nor nothing close to it since I'm over 8000 ft over sea level. I wouldn't think twice about putting a .91 FX on the Cap, and... oh... this doesn't look like a good first 3d plane to me. U should practice on a good fun fly plane first.
