T-51 kits are fabricated by Titan Aircraft Company at Austinburg, Ohio, in the United States and are being assembled and flown in several countries where they are popular with pilots and particularly with spectators at airshows. The aircraft has a wide range of handling abilities, from a stall speed of only 60 mph (97 km/h) to high performance up to 197 mph (317 km/h) and agility afforded by a +6g / -4g load limit capability. Titan has a long history with building aircraft to be flown under ultralight regulations, (see Titan Tornado) and now including the FAA Light-sport Aircraft category. Pilots choose whether they want to buy a kit which is fully complete and ready to assemble or a basic kit to which they add their own choices of propellers, engines, and instruments. Two versions are available: the experimental with retractable gear which must be flown by pilots with retractable gear experience and the amateur built fixed-landing-gear version which qualifies for the 1,200 lb (540 kg) and under weight category in New Zealand and Australia and can be flown by a sport pilot in the US. The most frequently applied powerplant is either the Honda V-6 or the GM LS3. One builder also considered a Mazda Rotary engine due to its power-to-weight ratios. Several planes used a Suzuki V-6 engine. The construction-to-flying time for the Titan T-51 is about 1400–1600 hours, longer if you have not experience. Weights and performance are dependent on model and engine choice. For the Titan T-51D page with more information, click here.
