I fly a little Titan Tornado S now and it is a blast. It's a full light weight metal aircraft with only 80hp (Rotax 912) but it will do a loop, actually more of an oval ellipse since it barely gets over the top and kind of falls off the back side. It cruises at C-172 speeds and has 2 seats in tandem and a stick rather than a yoke. A fun little experimental that carries about as much (600 lbs - that includes the 15 gallons of fuel) as its empty weight (~620lbs).
The reason I chose it is that the front seat height is pretty much even with the seat in my wheelchair (I'm paralyzed now so can't use feet/legs) and the rudder and brakes were easy to modify so that I can use my hands to operate all flight controls. Never consciously thought about how much I would miss flying until it was taken away for a little while. The first picture was when I test flew one before I bought mine, the second shot is my plane shot from a friends plane.
