Papa 51 Thunder Mustang

TerryLeave a comment

The Thunder Mustang was originally designed by Martin Hollmann for Dan Denny in 1988. Martin later finished the design and performed the flutter analysis for high performance aircraft.

Papa 51 Inc has produced kits to build Thunder Mustang two-seat 75 percent-scale representation of P-51 fighter, first flown 1996. Papa51 Co. Ltd., the original manufacturer of the Thunder Mustang is no longer in business.

The Thunder Mustang was not in production. The Thunder Builders Group L.L.C. acquired the assets required to manufacture the Thunder Mustang through foreclosure on a loan. These assets were posted as for sale.

First flown in 1996, the two seat Thunder Mustang offers its owner a unique blend of speed, maneuverability and mystique. Given the power to weight ratio, it outperforms the original North American P-51D fighter at a fraction of the cost.

Thunder Mustang kits are complete, containing everything from the spinner, prop and engine to the tail wheel, less your choice of instruments, avionics, paint and upholstery. Extensive prefabrication helps reduce construction time and eliminate hassles. The complete use of carbon fiber in the structure produces incredible strength and light weight.

The 8 foot diameter, constant-speed 4-blade prop is manufactured by MT Propellers. The gear box ratio of 2.8:1 turns the prop at 1607 RPM for the optimum ratio for the best prop efficiency and high speed with the V-12 turning 4500 RPM. The 100 lb. propeller is of composite construction utilizing a wood core, which is self-dampening and non-fatiguing. This saves weight compared to metal propellers and reduces the gyroscopic effect of the prop on takeoff.

Panzl PAN

TerryLeave a comment

Despite its superficial resemblance to a Pitts S-2, the Panzl Pan 1 N11ZL is an original 1987 homebuilt experimental biplane. It was a two-place cabin biplane, powered by a Franklin 6V-335.

The one built, N11ZL c/n ZL-1, won the EAA Champion Custom-Plans Built award at Oshkosh in 1990.

It was substantially damaged on March 18, 2003 during impact with terrain following a forced landing attempt near Vernal, Utah. The commercial pilot, who was the sole occupant on board, received minor injuries.

Pander Multipro

TerryLeave a comment

Designed by Theo Slot, who was responsible for all of Pander & Sons original designs, the Multipro is variously described as a side-by-side two seat or three seat light aircraft. It had high and almost constant chord wings, braced on each side by a V-form pair of struts fixed to the lower fuselage longerons. The fuselage was a rounded, plywood skinned structure, contemporaries remarking, as they had with other Panders, at the quality of the finish.

It was powered by a Pobjoy R 7-cylinder radial engine; the two blade propeller was driven via spur gears that reduced its speed and placed the output shaft above the engine centre, an unusual arrangement for a radial. The cabin was under the wing with a deep starboard-side access door and multi-panel glazing. The fuselage tapered aft, with the tailplane set half way up it and its fin and rudder together were almost triangular apart from a rounded tip. The Multipro’s conventional undercarriage was fixed, with the mainwheeels on V-sruts attached to the lower longerons and stabilized laterally by an inverted V-strut jointed at the fuselage central underside.

The Multipro flew for the first time in September 1932.

In all three Multipros were built. The first (PH-AIU c/n 42) and third (PH-AIX c/n 44) were rapidly sold to private individuals; the second (PH-AIV c/n 43) remained registered to the Pander works until 1937, when it too was bought privately. All remained on the Dutch civil aircraft register until at least 1939. One, the second aircraft, is known to have been destroyed by German bombing during the invasion of the Netherlands on 10 May 1940.

Wingspan: 11.30 m (37 ft 1 in)
Length: 7.80 m (25 ft 7 in)
Gross weight: 720 kg (1,587 lb)
