Proairsport. New ultra light glider/airplane

Curious what wings it's using. From the "airframe section" on their webpage, sorta sounds like they're using wings that are already "JAR certified", thus on an existing aircraft......

isn't it obvious? they look suspiciously similar to PW5 wings, and have the same span....

Pod and canopy look like PW5 (except for pointed nose). Undercarriage position is PW5. Only the boom and tail feathers are significantly different. Even the maximum weight is the same, though the empty weight is 10 kg less, despite the engine and funky powered dual mainwheel.

The PW-5 lawn darts over 50 kt. It takes a
bunch of work to go places, but the thing
has a nose for thermals.

Pulling up the wheels might flatten the
polar.

Finding space for the battery, jet and fuel
looks a challenge.

If the fuselage will accept PW-5 wings,
there's lots of PW-5s that might convert.

I've flown one or two hours in PW5, and even a few 250 or 300 km flights. It's worth flying 60 or 65 knots between thermals, but yes serious lawn dart by 80 knots (500 fpm down, 16:1)


Pulling up the wheels might flatten the polar.

Doubt it. It's the very thick wings hurt it at speed. Personal experience says Januses and DG1000 Clubs both go just fine at 100 knots with the wheel hanging out.

This thing looks awesome! I want one.
