Pop’s Props Pinocchio
First flown in 1994, the prototype is powered by a twin-carburetted, two cylinder VW, with plans that will include optional motor mount illustrations for Kawasaki installation. The aircraft boasts three-axis controls and large tail surfaces. Wings carry full-span ailerons and can be detached for trailering. Its wire-bracing, spoked wheels and radial cowling gives the craft a very nostalgic look.
All wood construction. Estimated hp of the 2 cylinder VW is 40-45 hp. Construction. The fuselage is all wood incorporating 3mm plywood skin from firewall to seat back and aft of the seat on the centre section. From there, full length gussets all the way to the tail of all four corners.
Laminated bows help round out the fin and rudder and scallops accent the elevator and rudder trailing edges. The stabiliser leading edge is .8mm ply wrapped around wood formers to create a rigid D box and wire bracing tops off the lightweight but strong tail package.
The 16% Clark Y airfoil and 54” chord were chosen for the wings because of its superior stall speed characteristics and high lift capabilities. 30 dihedral was added for stability and 20 of incidence. Teleflex push-pull cables operate the full span ailerons safely and precisely. Leading edge is .8mm plywood wrapped around 3/4” foam nose ribs with 1/8” ply formers at each end and on all butt joints. Wire bracing not only makes for quick and easy wing removal but adds to the look of early aviation. Fuel is pulled from a 4.8 USG plastic tank tucked neatly above the pilot’s shins and filler is recessed into the rounded aluminium cover. Laminated foam cowl cheeks taper the round cowling into the fuselage which makes for a smooth flowing transition.
“Pinocchio’s” airframe requires no welding, no fibreglass work and the prototype was designed and constructed in approximately 500 hrs.

Pope Southern Cross
The plane’s replica was the project of South Australian flying instructor John Pope, who created the plane as a travelling history lesson that would fly around the country. Southern Cross is a flying close replica of the famous record breaking Southern Cross Fokker FV11B of Sir Charles Kingsford Smith from the 1920s and 1930s.
Built in South Australia in the period 1980 to 1987 as a tribute to Smithy, the aircraft toured Australia during the 1988 Bicentenary raising money for the Royal Flying Doctor Service registered VH-USU.
She is a faithful replica built to modern standards using the traditional aircraft construction of steel tubing and timber with doped Irish Linen for the fuselage and an all wooden (spruce and plywood) wing. She is the largest “exact replica” aircraft in the world and has the largest one piece wing ever made in Australia.
Aircraft Research and Development Unit was tasked to carry out the test flying of a replica of the 1926 Fokker Tri-Motor as flown by Australian aviation pioneer, Sir Charles Kingsford-Smith. The purpose of the test programme was, firstly, to ensure safe operation of the aircraft throughout its proposed flight envelope and, secondly, to provide data to allow the issue of a Certificate of Airworthiness or Permit to Fly. The trial included a cockpit and systems assessment as well as an evaluation of the aircrafts flight and ground handling characteristics. Airborne assessments covered stability and control characteristics, stall characteristics, general aircraft performance, asymmetric power characteristics and an evaluation of the aircrafts take-off and landing performance and handling. The flight characteristics of the test aircraft were found to be similar to those expected from an original Fokker VIIb-3M. Consequently, the aircraft could not meet some modern certification requirements. Notwithstanding this the aircraft was found to be generally safe and airworthy provided it was operated by experienced pilots in daylight Visual Meteorological Conditions and that the main recommendations of this report are adopted.
The aircraft first flew in 1987 and during the 1988 Bicentenary she toured around Australia as a fund raising exhibit for the Royal Flying Doctor Service. The aircraft was a major drawcard to the 1988 Bicentennial Air Show and many thousands of people saw her. In 1990 the aircraft even ventured to New Zealand for air show appearances.
After 555 hrs flying tine, on the 25th of May 2002 it had an accident at Parafield South Australia when she lost a main wheel on takeoff. Landing on the one good wheel and the tail, the pilot kept the damaged wheel off the ground by keeping its wing high in the air. When the aircraft stopped the high wing came down and snapped off around 3 metres from the wing tip. HARS bought the damaged plane in 2000.
After considerable negotiation HARS acquired the aircraft from the SA Government in 2010. It is being restored to full airworthy status.

Pons Velocípedo Aéreo
The first attempt to create the planes in Cuba dates back to 1893, when the leader of Cuban independence Jose Marti Patriot was approached Arturo Comas Pons, Cuban agronomist and journalist, to create a flying machine “to make it applicable to uses of war “, steel and aluminum.
