Ultralight Aircraft Magazine - Diehl XTC hydro light is an amphibious ultralight aircraft. It uses a twin cylinder 24 horsepower KFM engine in a pusher configuration for power. It uses a canard and has twin tail rudders, and spoilerons on the wings.The pilot sits in the middle of the craft, with a small windshield. All three wheels retract and the nosewheel is steerable. The craft is very pitch sensitive and the 24 hp engine is not enough power for this weight and design of craft.

Ultralight Aircraft Magazine - Welcome to the Ultralight Aircraft News our goal is to cover as many aircraft expositions that host aircraft described as ultralight aircraft, light sport aircraft, experimental light sport aircraft, amateur built aircraft, ELSA or homebuilt aircraft that fit into the definition of ultralight aircraft in Canada or light sport aircraft, or experimental amateurbuilt light sport aircraft in the United States. 

These include three axis control aircraft, weight shift control aircraft, more commonly known as trikes, powered parachutes, helicopters, gyrocopters and powered para-gliders that meet the light sport or ultralight aircraft definition.

Airshows and aircraft expositions that we cover include, the Deland Sport Aviation Showcase, U.S. Sport Aviation Expo, Deland Sport Aviation Showcase, E.A.A.'s Sun N Fun, E.A.A.'s Airventure, the Midwest LSA Show, Copperstate, UPAC Convention and Aero Friedrichshafen in Germany. We try to regularly attend regional shows like the Arlington Fly-In, and Rocky Mountain Fly-In. 

Your subscription includes Rotax 582, and HKS aircraft engine rebuilding videos, which are EACH nearly 2 hours in length! PLUS hundreds and hundreds and hundreds of web video interviews with designers, manufactures, builders, and suppliers of ultralight light and light sport aircraft parts and accessories.
