FUSELAGE

The KITFOX~fuselage is a rigid structure built of 4130 chrome molybdenum steel tubing. The
wire used in the MIG welding process has higher tensile strength than the tubing, and the gas
mixture used enhances ductility and rust resistance. Critical areas such as the strut attach points
are stress relieved in the jig. Most control parts are TIG-welded for a neater appearance.

ManyKlTFOX~builders use Stits Epoxy Chromate Prirner to protect the steel fuselage and other
steel parts against rust and corrosion. Since about i November 1990, Denney Aerocraft
Company has offered as an option a baked-on “powder coat” finish available in any of several
colors.

The fuselage is covered with 1.8 oz./yd dacron bonded to the frame with Stits Poly-Tac,
heat-shrunk and sealed with Stits Poly-Brush. Most builders use Stits Poly-Spray as an ultra-violet
Iight barrier and undercoat, and Stits Poly-Tone and Aero-Thane to provide a beautiful, durable
finish coat.

IÀNDING GEAR AND BRAKES

The KITFOX~landing gear is of conventional desigri with 4130 chromoly main gear weldments
and rubber bungees. The main wheeis use 20” x 7.00” x 8” balloon type tires. Inflation pressure
of 9 psi (pounds per square inch) allows soft landings and uniform tire wear. Each KITFOX~kit
includes a 6-inch diameter steerable, full swiveling tail wheel. Some early Model i KITFOXTM are
equipped with cable-operated mechanical drum brakes, but virtually all Model 2’s and Model 3’s
are equipped with hydraulic disc brakes.
NOTE: Use only MIL SPEC H-5606E Brake Fluid in the hydraulic system. Do ~ use automotive
brake fluid or hydraulic fbuid, it is not compatible with the seals in aircraft brakes.

CONTROL SYSTEM AND SURFACES

The vertical fin, rudder, horizontal stabilizer, and elevator are all built of tubular 4130 chromoly
steel tubing and are fabric covered. The control surface hinges have polyethylene bushing
inserts, so do not require lubrication. Steel struts brace the horizontal stabilizer to the fuselage.

The KITFOX~is equipped with full span flaperons that function both as flaps and as ailerons. The
flaperons have a 3/4 inch tubular aluminum spar and are covered with an aluminum skin bonded
with 3-M “Scotch Weld” over a high-density foam core. The flap control lever is in the center of
the cabin in front of the seat where it is readily accessible to either pitot. It is used to adjust
flaperon deflection from 00 to 23°. The flaperon handle serves as the pitch trim control. Small
adjustments of the flaperon angle of attack (AOA) changes the angle of attack of the wing,
permitting very precise airspeed control. The fiaperon handle hinges on a friction pad that aliows
smooth adjustment of the flaperons and holds the flaperon handle wherever it is set.

The full span flaperons also serve as ailerons. They are mounted on hangers behind and below
the tralling edge of the wing so they provide powerful roll control even after a good portion of the

(04103191) 3
wing has stalled. Aileron input fram the stick and flap input from the flaperon control handle are
coordinated through the unique mixer bellcrank behind the seat to a~o’~v fuH ai!cron action at any
flap setting. The flaperons are hinged near the center at pressure, so aileron control forces are
light.

The flaperons and elevator are linked to the dual control sticks by a system af bellcranks and
push-pull tubes with aircraft quality rod ends. Aircraft quality 3/32” diameter cables connect the
rudder to the rudder pedals.

A vernier type throttle control similar to ones used on many other aircraft is providedas standard
equipment in the KITFOX~kit.

WINOS

Several factors contribute to the extraordinary short-field performance at the KITFOX~. One of
these is the unique design of the wing. It is a constant-chord, high-camber, high-lift airtoil
equipped with full-span flaperons. This airfoil achieves a CL Max of 2.8 with flaps applied.
Distinctive fiberglass drooped wingtips enhance the slow flight characteristics of the KITFOXTM.
The twa spars are identical 2.5-inch diameter tubes of 6061T6 aluminum, with 4 1/2-foot long “I-
Beam” type internal stiffeners riveted in place over the strut attach points. The front spar forms
the leading edge of the wing. Aluminum diagonal braces between the spars contribute to the
structural integrity at the wing. They are anchored to the spars with steel brackets rivetted in
place. The wooden ribs also serve as campression struts and are bonded to the spars with
epoxy structural adhesive. The adhesive used is 3M “Scotch-Weld”, an extremely durable and
strong adhesive that is widely used in the aircraft industry. The wing is covered with dacron fabric
bonded to the ribs, leading edge and trailing edge with Stits Poly-Tac, then heat-shrunk and
sealed with Stits Poly-Brush. Most builders elect to finish the wing with Stits Poly-Spray, the
“silver” coat that pratects the wing against deterioration caused by ultra-violet radiation, and Poly-
Tone ar Aero-Thane color coats.

FOLDING WINGS AND TOWABILITY

The wings at the KITFOX~can be folded alongside the fuselage so the airplane can be stored
in a smal! space. The folded airplane is less than 8 feet wide and can be towed on its own gear
fram the airfield to your garage or carport. This convenient feature of the KITFOX~eliminates
hangar rental, tie-down fees, exposure to weather and to a great exient, worries about theft and
vandalism. The KITFOX~wing hinges on the rear spar and the lower lift strut attach point. With
practice, the wings can be folded in only 3 or 4 minutes.

To fold the wing:

1. Chock the wheels.
2. Release the 7 winged camlocks and remove the turUedeck.
3. Center the control stick Iaterally.
4. Remove the front spar attach pin.
5. Swing the wing back and secure it with the wing lock-back brace.
(Hold the wing and swing it back gently).

(04/03191) 4
NOTE: Do not fold the wing with a full wing tank. Fuel may overfbow thraugh the cap ar vent and
onto the wing.

The optional towbar straddles the tailwheel and attaches to the fuselage with two pins.
Attachment takes about 3 minutes and you are ready to go! The airplane should not be towed
on its own gear for lang distances (more than 10 miles). But for trips to the airport at moderate
speeds the towbar works fine. For longer trips, the KITFOX1~’can be carried on a trailer without
undue stress ar wear. Denney Aerocraft Company offers as an opt~ana trailer similar ta the ane
on which we have hauled our own demonstrators tens of thousands at miles without damage.
If you build your own trailer, be sure to build a bracket to suppart the tall during transport. This
will prevent straightening ar breaking the tailspring.

ENGINES, GEARBOXES AND PROPELLERS

The standard KITFOX’~engine is the liquid-cooled Rotax 582LC. The Ratax 912 (also liquid-
cooled) is available as an option.

The Rotax 582LC is cooled by ram air through a specially designed radiatar mounted on the belly
of the KITFOXTM. This fine littie engine produces 65 h.p. at 6500 RPM. It is a 2-cylinder 2-cycie
engine with dual electranic ignition and has an oil injection system to provide lubrication. Until
late 1990, only the standard Ratax gearbox (Type “B”) was fitted. It has a reduction ratlo of 2.58
to 1. Late in 1990 the Type “G” gearbox became available. lt is a heavier unit (6 lbs. heavier)
which may be fitted with different sets of gears with reduction ratios of 2.62 to 1, 3 to 1, 3.4 to 1,
ar 4 to 1. Since December 1, 1990, Denney Aerocraft has offered as an option the Type “0”
gearbox, usually with a 3 to i ratlo. The 582LC Rotax engine-gearbox-prop combination
produces about of 375 lbs. af static thrust which is outstanding in relationship to the empty weight
at the airplane, compared to many other types at aircraft. An operator’s manual is supplied with
each engine for more complete information.

The Rotax 912 produces 80 h.p. at 5500 RPM. It is a 4-cycie, 4-cylinder, horizontally opposed
engine designed specifically for aircraft use. It has dual ignition with twa breakerless capacitor
discharge systems completely independent at ane another. The reduction unit is integral to the
crankcase and the standard gear ratio is 2.27 to 1. The cylinders are air-caoled and the cylinder
heads are liquid coaled. The Rotax 912 produces about 435 pounds at static thrust. The Ratax
912 engine is equipped with dual Bing carburetors that automatically adjust the fuel-air mixture
to changes in atmospheric pressure. The kit includes a carburetor heat system similar to those
used an normally aspirated engines in many certified airplanes. See the Rotax 912 Operators
Manual supplied with the engine for more complete information about this fine engine.

A 66 inch diameter 3-blade wooden fixed pitch propeller is standard equipment for the KITFOX~
with the Rotax 582LC engine. A graund adjustable 3-blade prop is an option.

A 68-inch diameter 3-blade wooden tixed pitch propeller is supplied with the Rotax 912 engine.
A ground adjustable prop is available.

(04/03191) 5
 FUEL SYSTEM
The standard fuel cell for the KITFOXN equipped with the Rotax 582LC fits between the firewall
and the instrument panel and has a capacity at 9.75 U.S. gallons. it is rotationally molded at
cross link polyethylene, a very strong and durable material that withstands extremes at cold and
heat. The fuel tanks at many new cars are made of this material, as are the familiar red Fire-
Marshall approved “jerry” cans. The standard fuel tank cannot be used if the optional Rotax 912
engine is installed, so the bullder must use any of severa! possible wing tank configurations and
the i 1/2 gallan heàder tank.

Optional 6-gallon aluminum ar fiberglass wing tanks are available. Also avallable are 13.5 gallon
fiberglass wing tanks. One ar two wing tanks may be installed in conjunction with the standard
fuel tank, or the standard fuel tank may be replaced by a 1 1/2 gallon cylindrical aluminum header
tank. Generally, aircraft equipped with the Rotax 582LC wiR have the header tank installed an the
back side at the firewall, while those with the Rotax 912 will have the header tank attached to
fuselage crosstubes behind the seat and the mixer bellcrank.

Each wing tank has its own shut-off valve to control fuel flow into the standard tank ar header
tank, and there is another (primary) fuel shut-off valve at the firewall.
A vacuum-operated fuel pump (582LC) ar a mechanical tuel pump (912) pumps fuel fram the
standard tank ar header tank ta the carburetors.

ELECTRICAL SYSTEM

The Rotax 582LC has a 12 volt built-in alternator that produces 165 watts @ 13.75 amps, and a
i 2-volt starter. A battery, regulator/rectifier, relay, and keyed start switch are included in the kit.
The 12 volt battery is mounted in the fuselage aft at the seat, or on the firewall if dual wing tanks
and header tank are installed. A master switch on a 30 amp. breaker activates the system. The
582LC engine features a dual ignition system with breakerless capacitor discharge (CDI).

The Rotax 912 has a 12 valt, 22-amp, 270 watt generator and a 12-volt starter. A battery,
regulator/rectitier, relay, and keyed start switch are included in the kit. The battery is mounted aft
of the seat. The 912 is equipped with dual CDI (capacitor discharge ignition).

FINISH

The fabric supplied with the KITFOX’~’kit is 1.8 oz/yd2 dacron. Stits Poly-Tac and Paly-Brush are
provided to secure the fabric to the airframe and seal the fabric atter it has been heat-shrunk.
Most buliders elect to provide ultra-violet protection for the fabric by applying Stits Poly-Spray,
which also serves as a sanding base for the color caats of Stits Poly-Tone ar Aero-Thane.

FLIGHT CHARACTERIST!CS

The rigid, fabric covered fuselage at the KITFOXN is a time-proven design similar to that atseveral
classic airplanes, including the Piper Cub, Taylorcraft, and the Champ. Its 3-axis contral system
is also similar, so the general tlight characteristics are similar. Its huge flaperons lend the
KITFOX~superior controllability at very 10w airspeeds, and its Iight weight, high power loading,
and high lift wing contribute to its outstanding maneuverability and short take-off capability. The
10w wing Ioading of the KITFOX~means it will be affected more by wind than larger, heavier
aircraft. The KITFOX~is not designed for flight in hazardous weather or under Instrument Flight
Rules.
KITFQX~FLIGHT TIPS

o The KLTFOX~is a high performance airpiane at slow speeds. Until you are thoroughly familiar
with its flight characteristics, restrict take-off power to about 75% at full power. This is plenty
of power to safely operate the aircraft and the take-off rolI and climb will be more comfortable
and easier to manage.

° Application at flaps causes the center of lift of the wing to move att. This causes the airplane
to pitch nose down, which tendency must be cauntered by up elevator. The use at flaps and
the resulting changes in control ‘~eel”shauld be explored at altitude. Use very little ar no
flaps for the initial take-off in your new KITFOX~.

o You should build a stop for the flap handle to restrict fiap deflection to 23°. Deflection beyond
23° tends to restrict aileron travel and effectiveness. Exercise caution on final approach in
gusty ar crosswind conditions not to use sa much flaps that aileron effectiveness is
diminished.

° Your K1TFOX~will safely land at speeds of only 33 35 mph. However, the airspeed will
-

bleed off rather quickly in the flare, sa it is best to carry same speed on short final. Initially,
yau should maintain 55 60 mph on tinal. Atter same practice, you can slow your final
-

approach speed to 45 mph, solo. Do flat hesitate to use power to arrest the sink rate if you
tind the aircraft settling too rapidly, or to use full power to go around and try again.

° The KITFOX~has a Iow wing loading so you must exercise caution on rollaut and while
taxiing in strong winds. The large control surfaces are very effective in cauntering crosswinds
if used properly. Most importantly, if winds are strong, ~Q SLOW.

o Pilots who have not flown airplanes as smal! as the KITFOX~may be surprised by its
responsiveness and its Iight control feel. You can fly it with your fingertips and tiptaes, and
once mastered it is a delight to fly. The tendency of first-time KITFOX~flyers is ta over
control. Don’t do itl To properly execute any maneuver, same rudder input is required.
Usually very little pressure is necessary, but you must use the rudder. We strongly
recommend that you install a slip-skid indicator to help you “find your seat”.

 BEFORE THE FIRST FLIGHT

Before the initial flight, the KITFOX~must be inspected and approved for flight by an FAA
inspector (ar designee). It is a good idea to work ciosely with the inspector during construction for
he will have many good tips aud advice about home-built aircraft aud their construction. The
inspector can also supply you with a Suggested Inspection Checklist For Amateur Built Aircraft.

DOCUMENTATION

Useful Publications

A good source for more complete informatiou about licensing and regulation of homebuilt aircraft
is: How to License a Homebuilt Aircraft, by Paul Bergen Abbott.

Take the time to develop an orderly aud systematic flight test program. The U.S. Department of
Trausportatiou (FAA) publishes a compreheusive Advisory Circular titled Amateur-Built Aircraft
Flight Testing Handbook. It coutains checklists and outlines a complete test program. We strongly
recommeud each builder order a copy aud use it to develop his test program.
Order yours by writing to: Superinteudeut of Documents, U.S. Governmeut Printing Office,
Washington, D.C. 20402. Ask for AC No: 90-89.

Log Book You must prepare a log book before inspection of your aircraft by the FAA. Use it to
-

record identifying information aud any maintenance and repairs.

Instrumentatiou Certain instrumeuts must be installed in your aircraft before you fly it. Those
-

required in the K1TFOX~in the U.S. include airspeed indicator, altimeter, compass, tachometer,
engine temperature gauge, fuel quantity indicator aud for the 912 engine, an oil pressure gauge.

Markings -

‘N’ Number your KITFOX~must be markedwith its registration number before inspection.
-

Experimental because it is licensed in the “experimental” category, it must also be marked

-

EXPERIMENTAL~according to U.S. regulations.

[.D. Plate Every aircraft in the U.S. must carry a fireproof identification plate engraved with
