I have the V1 fox since 10 years (I must confess, I had more than one of them, but lost one due to broken receiver, and another after a midair with a big towplane) and it still performs well. The V1 doesn't have the flaps. Other than that it performs still very well. I completed a pair of wings with LED's to have a night aerobatic glider... After 10 years everything weared out quite a bit, it has no resell value whatever, but it is still to launch it now and then. If you're looking for a good foam glider, capable of thermals for quite some time this isn't the right plane. But if you're looking for a good foam aerobatic glider, this is the sweet spot.
I also did a bit of climbing with motor on, and then doing aerobatics with motor off, but it takes a long time to get good altitude, and the plane loses energy very quickly, so there's not a lot of time to actually enjoy motor off aerobatics (like you would do with some bigger composite glider).
