Teichfuss Nibio

The Teichfuss Nibio (the German-speaking Teichfuss’s spelling of the Italian Nibbio or English: Kite) was an Italian single seat glider, designed by Luigi Teichfuss.

The original Nibio, the Nibio I was designed as a primary glider and was built in the Royal Aircraft factory at Pavullo nel Frignano Airport during 1929. Apart from its span of 12.5 m (41 ft 0 in), empty weight of 145 kg (320 lb) and all-up weight of 220 kg (485 lb) very little information on it exists. Some launches were made by aerotow, behind an Aviatik from Taliedo. The Nibio II, sometimes known as the Nibio II Freccia Nera (English: Black Arrow) followed the next year with a new wing. Its greater span, increased by 900 mm (35 in), provided an increase in aspect ratio. Despite its longer wing the Nibio II was 20 kg (44 lb) lighter.

The Nibio II was a high-wing monoplane with its wing braced by a single faired strut on each side, joining the lower fuselage to the outer end of the central panel at about one third span. This central panel was rectangular in plan and was without dihedral. The outer panels were straight tapered to blunt tips, the wing becoming thinner and thus acquiring dihedral though retaining a horizontal upper surface. Ailerons occupied the whole trailing edges of these outer panels; there were no inboard flaps or air brakes.

Its wood framed, plywood skinned fuselage was hexagonal in cross section, tapering markedly on its underside towards the tail. The wing was mounted on a pedestal which sloped away aft into the upper fuselage. The pilot’s cockpit, open behind a small windscreen, was immediately ahead of the pedestal and below the wing leading edge. The tail surfaces were straight tapered and straight tipped, with the tailplane mounted on the fuselage. The rudder extended down to the keel, operating within a small cut-out between the elevators and protected from the ground by a small underfin which served as a tail bumper. There was a short landing skid running from near the nose to just aft of the wing strut.

Only one of each version was ever built.

Teichfuss Balilla

The Teichfuss Balilla was an Italian single seat primary glider, designed by Luigi Teichfuss.

In 1939 Luigi Teichfuss designed an improved version of the Nibio I, the Balilla. It was a simple, low cost, robust, high wing, strut braced monoplane with an unswept, constant chord, elliptically tipped wing. Mounted with dihedral, this was supported over the fuselage on a narrow pedestal and braced on each side by a parallel pair of faired lift struts from the lower fuselage to the wings at about half span.

Its fuselage was wood framed, flat sided and plywood skinned. Its cockpit, open but with a small windscreen, was immediately ahead of the wing leading edge; there were no instruments. The Balilla’s tail surfaces were all straight edged: the tailplane, single strut braced from below, had a sharply swept leading edge and carried elevators with angled tips and a cut-out for rudder movement. The vertical tail was tapered with a squared tip; the rudder reached to the keel, where it was protected by a wire loop tail bumper. Elevators and the rudder lacked aerodynamic balances. A conventional skid, running from the nose to below the wing trailing edge formed the undercarriage.

The Ballila first flew in 1939. Ten were built, serving all the gliding schools of the R.U.N.A. It could be winch launched and was straightforward to fly, training novice pilots to their B-certificate.

Taylorcraft Model F / F-19 / F-21

With origins in the Taylorcraft Model B of the early 1940s, the F-19 and F-20 are revived and improved versions of the Models 19 and 20. Three models of the F-19 Sportsman were offered as Standard, Custom, and Deluxe. There was a modernisation after Continental suspended production of the O-200 engine.

A higher-powered version, the F-21 two-seat sporting trainer, was designed with aluminium ‘T’-beam wing spars and a new fuel system. This in turn has given way to the F-22.

The F-21B has been certificated in Australia, and the manufacturer hoped that this would generate sufficient interest for the production line to start up again. The price for a standard, equipped aircraft had risen to $33,000, which Taylorcraft says reflected higher engine costs, which are “going out of sight”.

The 1979 T Craft was the F model. With 100 horsepower, it weighs 900 pounds and it can lift another 600 pounds. The T Craft tops out at 110 knots, it stalls at 37, and it departs or returns to Earth fully loaded over a 50 foot obstacle in 375 feet. It will cruise 350 miles while sipping six gallons an hour.

The F-19 was built until 1980.

Built in 1979 at the plant in Alliance, Ohio, wrapped in Dacron and painted, each T Craft is towed a couple of miles out to Barber Field for final assembly.

The F-21 was first built in 1980.

1980 Taylorcraft F-21

Taylorcraft production includes 100 prewar Model As, 1800 military L-2s, more than 2800 post-war BC-12Ds, and more than 120 F-19 Sportsmans.

Taylorcraft E-2 Cub / F-2 Cub / G-2 Cub / H-2 Cub

Taylor E-2 Prototype NC10547 with C G Taylor and company pilot Bud Havens

Taylor first built a glider that looked like a small Breezy and the E 2 Cub evolved from towing that glider behind a car up and down the Bradford runway.

Designed by C. Gilbert Taylor in 1930 and produced as the Taylor E 2 Cub in 1931, much of the inspiration and many of the design goals for the airplane came from W.T. Piper, Sr. Taylor selected the U.S.A. 35B airfoil for the Cub. This airfoil had a reputation for providing favorable flying qualities at low speeds; all subsequent Cubs. The E 2 was open air except for a windshield and had squared off wingtips and tail surfaces. The tandem cockpit of the E 2 was without side windows, but a young man named Waiter Jamouneau, subsequently chief engineer and now a vice president at Piper, designed optional sliding side windows and a door arrangement that remain features of the Super Cub.

Reliable lightplane engines were virtually nonexistent when the E 2 was designed. For the first E 2, Taylor found a two cylinder engine of 20 horsepower. It was known as the Brownbach Tiger Kitten, and the name reportedly inspired the E 2 to be called the Cub. The plane handled fine on its first flight (in September 1930) but on 20 hp didn’t get too high five feet, actually The new Taylor E-2, now known as the “Cub,” was meant to be an affordable aircraft that would encourage interest in aviation and was awarded its type certificate on July 11, 1931 and licensed by the U.S. Department of Commerce for manufacture.

Twenty-two Taylor E-2 Cubs were sold during 1931, retailing for $1,325; by 1935, sales had increased to more than 200 E-2 Cubs.

A 45 hp, nine-cylinder French Salmson AD-9 was tried: its performance was spectacular, but it was too expensive.

Continental provided the solution with the A 40, a “40 hp” flat four that actually produced 37 hp. The E 2 was certified with this engine on June 15, 1932 and was put on the market for $1,325, or $1,495 with optional 40hp Aeromarine AR-3 engine, or $895 less motor.

Unfortunately, the early Continentals were giving trouble, for the engine company was using the Cubs as test beds. One of Piper’s five children, Tony, said that he rarely got more than 20 miles per forced landing. Sales to people who wanted to fly longer between stops were, naturally, a little sluggish. There was a frustrating period before Continental improved the A 40 during which Taylor actually started designing his own engine.

Continental added dual ignition and cured the annoyances of blowing head gaskets and breaking crankshafts.

Taylor E-2 NC15370 with A-40 engine

The Prototype (s/n 11) was powered by a 20 hp Brownbach Tiger Kitten and was first flown on September 12, 1930. The E2 barely managed to leave the ground with the tiger kitten, however the engine left a legacy in that it prompted one of C.G. Taylor’s colleagues to remark that since the engine was called the Tiger Kitten the E2 should be called the cub. The engine was deemed too weak and a 40 hp French Salmson was tried and deemed too expensive. Ultimately the decision was made to try a brand new and untried 40 hp engine from continental. That engine was an air cooled flat four cylinder designated the A-40. An uncertified A-40 was fitted to s/n 12 which was completed on April 9, 1931. The engine had a number of teething problems and Taylor has been quoted as saying that in the first 30 days of flying with the A-40 the E2 had to make 26 forced landings. It was also discovered that the crankshaft’s tended to break at around 100 hours.

Continental eventually worked the bugs out and the A-40 received its certification on May 15, 1931 which cleared the way for the E2 aircraft certification on June 15, 1931. The E2 was originaly certified under group 2, no 2-358 which covered the first 14 aircraft. The remaining aircraft were certified under ATC A455 which was issued on November 7, 1931 (covering s/n 26 and up.) The aircraft originaly sold for $1325 and no options were offered. The fuel tank was moved from the wing as shown on s/n 12 to the fuselage where it was located between the panel and the firewall starting with s/n 13. A fully enclosed cockpit was introduced on February 9, 1932 and became standard starting with s/n 35 and up.

Sales reflected the improvements, and 351 E 2s were produced between 1931 and 1936.

E-2

In the midst of the depression Continental announced that they were getting out of the aircraft engine business (a decision they later changed.) As a result the Aeromarine AR3-40 (40 hp) was installed starting with s/n 75 (3 Jan 34). This new configuration was designated the F2 cub. The Aeromarine was not satisfactory and several further engines were tried (models G2 with a Taylor designed T-40 and the H2 with a 35 hp Szekely SR-3-35.) Eventually Continental updated to the A-40-3 and this engine was used for s/n 178 and up.

The company was always sensitive to customer desires, and in 1936, Taylor introduced a refined Cub in order to incorporate design improvements as well as suggestions from the field. A young man named Walter Jamouneau was given the job of improving the E 2 resulting in the Piper J 2. In 1937 a fire destroyed the plant, prompting the company to relocate to a defunct textile mill in a town called Lock Haven. In November of 1937, the relocated company changed its name and became the Piper Aircraft Corporation.

The 1934 Taylor F-2 Cub (ATC 525) featured and open-sided cabin with optional side panels. Selling for $1,470, about 30 were built.

The 1934 Taylor G-2 Cub was an F-2 with a 40hp Taylor T-50 experimental motor. Only the one was coverted, N14756, which was rebuilt as an H-2 Cub in 1935.

The 1935 Taylor H-2 Cub (ATC 572) featured an open-sided cabin with optional side panels. Selling for $1,425, at least four were built.

Taylorcraft A / Taylor-Young Model A / Alliance A

Taylorcraft A NC19866

The birth of Taylorcraft came in early 1936 when city fathers offered C G Taylor the old Hess-Argo factory rent-free in order to encourage new industry. William C Young entered the picture as a partner in April 1937, and city support was dramatically demonstrated in late 1937 in the sale to townspeople of more than 35,000 shares of company stock for needed capital.

The Taylorcraft A represents the first model series of the line, and it is powered by the 40-horsepower Continental A40-4 engine, one of the first to use opposed cylinders. The engine came out in the early 1930s and was used on the Taylor Cub that later became the Piper Cub. The huge tachometer, oil temperature gauge, and oil pressure gauge were bought by Taylorcraft from the same supplier that sold the units to the Dodge car company, and relabeled. (They were used in the early Luscombes, too.) As the model numbers increased, so did the number of doors: one with the A, two with the B, and three with the 15A and 20.

The prototype, NX16393 c/n 25, was built by Taylor Aviation Co under (2-529) and subsequent planes by Taylor-Young Airplane Co under (ATC 643). Selling in 1936 for $1,495 and $1,595 in 1938. With company reorganization in 1938 it gained a “craft” and the Taylor-Young A became known and advertised as Taylorcraft A.

Taylorcraft production includes 100 prewar Model As, 1800 military L-2s, more than 2800 post-war BC-12Ds, and more than 120 F-19 Sportsmans.

A total of 606 were built. Prototype NX16393, NC15757-15763, NC15776, NC18301-18347, NC18349-18373, NC19000-19099, NC19600-19699, NC19800-19818, NC19821-19895.

Taylorcraft Glider

Piper was new to the airplane business but not to business principles, so he asked Taylor to design an inexpensive, easy to fly trainer that the average person could afford to rent. Most of the training planes of the time were older, relatively heavy biplanes requiring correspondingly powerful engines. The cost of learning to fly was therefore quite high. Piper figured that an airplane cheap to buy and operate might cut that cost in half, enabling more people to fly, which would require operators to buy more planes from him.

Taylor first built a glider that looked like a small Breezy. Those who later called the Cubs powered gliders were not far from wrong, because the E 2 Cub evolved from towing that glider behind a car up and down the Bradford runway.
