Hello George,

Is this what you had in mind?

"Pocket Rocket" Is The 450hp Turbine-Powered Light Plane Of Your Dreams

Take an Impulse 100 http://www.pilotfriend.com/experimental/acft3/80.htm very
light plane, beef up its structure and elongate it, and then strap a
450-horsepower Allison turbine to the front of it and you end up with one fast
and fun daemon of the skies that also looks freakin’ awesome!

Oh, and considering the locale and unique home of the Pocket Rocket shown in
the video below, its owner may be a Bond villain:

Just listen to this thing start up, run and shut down. The soundtrack is almost
worth the price of admission alone!

According to Gonzoaviation.com these are the basic performance specifications
for this one-off aggressive flying machine:

Max cruise at 2,000ft - 220 kts

Cruise at 16000ft - 282 kts

Rate of Climb @ 80 kts 6200 ft/ min.

@130 kts 4200 ft/min.

Rate of descend @180 kts 6000 ft/ min.

Stall power on: none, climbs with 80° nose up
Stall power off: 39 kts

Structural G limit +10/-10

This thing is like a balls-out anime version of the Marchetti SF-260C with a
tail wheel and I want one.

Impulse 100

With the Impulse 100, an interesting high-performance ultralight aircraft is
due for his first flight at the Baden Airport. If everything goes accordingly
the aircraft could first fly in January. The following flight test will be
conducted in Southern France due to weather and timing constraints. The
certification is expected for May. The Impulse will supposedly offer a maximum
speed of 330 km/h. The calculated cruise speed is at 270 km/h, the manoeuvring
airspeed at 220 km/h. The manufacturer, Impulse Aircraft, is listing the range
at 1700 km plus a one hour reserve. The Impulse 100 is entirely made in a
carbon honeycomb sandwich. The aircraft stands on a fixed gear, a version with
a retractable undercarriage is projected for the future. With a fixed propeller
and a basic instrumentation, the aircraft is listed for DM129500 plus VAT.
According to its designer, Philipp Steinbach, the good looking and performance
wise promising ultralight aircraft will be suitable for glider towing.
