Don't know about the UK but I flew them in Bulgaria a while back. Fully aerobatic two-up but a bit spoilt in that respect as it has a yoke not a stick. Built like a brick ****house with a spacious cabin and very strong undercarriage. Not very comfy seats as they were little more than tubular steel with canvas and a bit of padding, and with little curtains for all the windows for blind flying (don't think the CAA like them though). And a MASSIVE pitch up force when you pop the flaps - one setting pneumatic affairs that go to about 50 or 60 degrees in about a second, whahay!
When all's said and done, though, a fully aerobatic four-seater tourer has a lot going for it
