Alisport has been doing some amazing things with their sport
glider series for several years now... in addition to developing a
very fine self-launched kit aircraft, as well as an electrically
powered version, they have now turned their attention to jet
power.
The first test flights of a jet-powered Silent sailplane have been
conducted by an independent group working closely with Alisport to
analyze the potential for future development of turbine-powered
sailplanes. Powered by twin AMT USA engines (usually seen on larger
model jet aircraft), the 12m Silent easily self-launched with what
were determined to be "acceptable take-off distance and good climb
rate."
