I've flown both the -7 and the Virus, but not the Virus SW. A few points:
* The RV-7 is an airplane, the Virus SW is a glider that requires a self-launch endorsement. In other words, a written exam and appropriate transition training for a glider license. You should not have to learn to fly unpowered gliders, though;
* The Virus SW as a glider requires **no** medical at all, just you self-certifying that you're healthy;
* I flew the nosewheel Virus. From looking at the geometry, the tailwheel Virus might require better than average tailwheel skills;
* Double check what propeller comes on the Virus. I'm not sure of all the details (again), but a variable pitch prop would help a lot with the small engines that you might find on your Virus SW;
* The Virus flies like a sailplane with all those rudder coordination requirements;
* The Virus and all those that share the same fuselage have a steel tube above the seats for you to bump your head on in turbulence. Double check how much clearance you will have in normal seating positionS. More than one seating position.
* If you ever plan to fly IFR, you might run headlong into the FARs. Last I checked, IFR in a glider requires some amount of airplane IFR currency, but I'm not up to date on that. Nor am I up to date on how much this would apply to self-launching gliders;
* Yes, you can fly a Virus SW more or less like an airplane in terms of when, where, etc. No idea about the ride in turbulence;
* Virus SW should fit into a standard hangar.
I flew the Virus for a pilot report and, with just over an hour in the logbook, I paid for another hour plus of dual to get the self-launch endorsement on my glider ticket. Not hard, but different.
It's been a while since I flew the Virus, so double check everything I wrote. I, too, think that the Virus SW is a really cool bird, but I'd expect it to fly a whole lot more like a sailplane than an airplane.
I've talked to several Pipistrel folks over the years at air shows and they've all been great to talk to. Tell 'em I sent you, please.
