| Overview |
The
airplane was designed to appeal to those who admire aircraft of the late WWI vintage. As
such, it has the appearance of many of them, and no one particular. It is original and
modern in aerodynamics. It is lively and responsive but normal in behavior and presents no
problem to anyone who could land a Taylorcraft in a light crosswind with no passenger
aboard. Although it flies like a fighter in that it will go willingly where you point it,
it is stable in all axis and presents a light well proportioned, positive feel in all
controls. The differential ailerons permit positive action right into the stall and create
no surprises. Stick against the rear stop, a definite buffet is felt where upon the nose
drops gently, the wings unstall, and almost immediately, the stall is reentered. This will
continue until back pressure is eased off. It is quite easy to land and should be
three-pointed. Rollout is steady even with the tail wheel unlocked. |
| Taxiing |
The
W-11 is quite firm while taxing in cross winds. 40 mile gusts at 90 degrees present no
problems even on asphalt. The stick must be forward when taxing downwind. |
| Crew
Comfort |
All
this has been accomplished in a rather light but very strong structure with a surprisingly
roomy, draft free cockpit. Visibility in all axis is excellent. Pilots up to
61" and 200 lbs. Can be accommodated. |
| Structure |
One
design requirement in construction was economy in construction and operation. A straight
forward wooden construction of de Havilland type provides a strong, resilient and long
lasting airplane. Every piece, fitting, bolt and wire have been analyzed for weight and
strength. While it could perform well on 50 H.P. the 65 H.P. Continental was chosen for
its durability, economy of operation and power at low RPMs. The latter is very important
to short field performance. A 90-100 H.P. engine would not improve takeoff because of
weight and higher RPM. They would increase top speed a very little, but that is not
important to a fun machine. Landing speed would increase and that is undesirable. This
machine is designed and stressed for the A-65. No other is recommended. |
| Flying
Characteristics |
While
the design is strong enough for mild "inside" aerobatics, it is not intended as
a trainer or performer for all-out aerobatics. That is a completely different design
requirement. If it were stabe enough for IFR flying, it wouldnt be any fun for just
flying enjoyment. The Boredom Fighter is just that, a friendly delight to fly with amazing
short field capability. |
| Basic
Building |
The
fuselage and tail may be built like a model on a 2 x 12 foot table, and the wings may be
assembled on two vertical floor to ceiling posts which were the 2 rails for the table. |
| Required
Tools |
The
only special tools needed are a good table saw with a sharp planner blade, Sabre saw,
drill press, variable speed ¼" hand drill, and a few sharp hand tools. A number of
clamps will be needed also. Welding has been kept to a minimum. All welds are easy to
make. The sequence is in the plans. |
| Glue |
Exotic
glues are not necessary. Weldwood Plastic Resin provides joints stronger than wood. It is
low in toxicity and provides a wide tolerance to temperature and pot life. If you promise
never to boil the airplane, it will outlast you. |
| Drawings |
Accurate,
professional drawings are available. They provide every dimension of every part and
assembly. They are drawn in a logical order of procedure with references to each other for
clarification where pertinent. Process and procedure information is provided so that a
reasonably good mechanic can produce a really professional job. 45 drawings, 11 x 17, are
supplied. The prototype received an EAA award for best wooden construction. The drawings
depict the prototype exactly. |
| Wood
material |
It
is recommended that grade A aircraft spruce be used, "select" for spars. Procure
it milled two sides in the nominal thickness. One inch is needed for front wing spars,
tail spars and firewall frame. All the balance is 7/8 thick. These milled planks usually
run 7 to 8 inches wide and are priced as if 6 inched wide (ie. A ten foot plank is
considered as five board feet). The overage is used for fairing strips, rib stock and
such. |
Cost
(1979 $$s) |
Using
raw materials, in 1979, only and new A-N fastenings, the cost of the prototype was $1200
for the entire project, exclusive of engine and propeller. The latter is wood 72"
diameter and 43" pitch, a standard item for the Taylorcraft, Funk, Aeronca, and such.
The ideal prop would be a 72 x 42
Do not use a metal prop. |
| Wheels/
Brakes |
Used
6 x 6 Taylorcraft wheels and brakes go for about $50 a pair. The mechanical brakes on
these Shinn or Firestone wheels are poor on Taylorcrafts, but rigged as shown on the
plans, are as powerful as can be used. Light and reliable, they cannot leak "paint
remover" into the fuselage. |
| Construction
Time |
Construction
time varies with the builder. Actual construction time for the prototype was about 1500
hours. The job was not rushed, it was enjoyed! The design employs only material and
techniques which will endure and be reliable and light. IT is no more difficult to make
than a Pietonpol. Above all, peace of mind in flight is paramount. No revered classic
exceeds this airplane in this regard. |

Performance Data |
The
performance data is conservative and verified by stop watch timed-flight averages. |
| Plans
Cost |
The
plans set sells for $125 in USA Money Order or bank check. |
| Flutter
Testing |
P.S. The
prototype was flutter tested in 5 mile increments to 146 MPH and found to be flutter free. |
