Shown below is the Warner Revolution II and
SpaceWalker II Aerocraft.
The nostalgic look of a 1930 type aerocraft has been recreated here in a modern
aeroplane that is affordable to build and fly. All of us at Warner Aerocraft are pilots who
love to fly. We are dedicated to helping as many people as possible build their own
flying machine so that they too can experience the fun we have with ours.

Shown Below Is The "Sportster"
Our Newest Design.
Many people wanted the look of elliptical wings and others wanted a wider longer
fuselage that has increased luggage room and can carry heavier, taller people. The
new but nostalgic looking Sportster has been designed to fit the bill perfectly. If you've
yearned to fly a 1930 racer, this plane is for you!

Airframe: Conventional steel tube fuselage covered in your choice of fabric. Factory
MIG or TIG (optional) welded.
Wings: A conventional wood I-beam spar that has been boxed in for durability.
Wood ribs with 4130 steel truss attachments between the front and rear spar. The wing
is covered in the fabric of your choice. The wing leading edge is 2mm plywood for a
clean straight line. The trailing edge of the revolution is aluminum, pre-bent into the
correct shape. The wing consists of three pieces, the two outer sections and the center
section. The ailerons are constructed similar to the wing with the exception that only I
spar is used. A I mm plywood leading edge is used as well as the aluminum trailing
edge on the revolution.
Towable: The outer wing panels are readily detachable from the airframe and the
center section stays as part of the fuselage. In this configuration the aeroplane is easily
towed by a car, either on a trailer or with a special hook that allows towing the
aeroplane on its main gear.
Page 5 of 16
Landing gear: Taildragger, Non-retractable main and tail wheel. Landing shock is
absorbed by springs in the landing gear and is built to absorb a lot of abuse. Grass field
operations are a breeze with this landing gear.
Brakes: Cleveland disk with dual pedals. Independent left and right side systems.
Power plant: We supply motor mounts for Continental and Lycoming engine
installations. Engines from 85 to 150 HP are approved for use on the aeroplane. Our
factory aeroplane uses a Lycoming 0-290D, 125 HP and a metal Sensich propeller. A
number of builders are working on a Subaru installation and also the Upside down
Menasco engine. At 100mph we are at 50% power, and burn about 5 gallons per hour
of auto fuel. We cruise in style for $6 per hour of fuel.
Seating: Two in tandem. .. the Revolution aerocraft fits people up to about 6' (without
modification) and will carry aloft two 220 lb. people and full fuel. The Sportster will fit
people up to 6'5" and 250 lb. each, other modified variations are possible.

Additional Features: Cockpit elevator trim. Plenty of head room! Simple entry and exit.
High Quality Materials And Construction: Chrome Moly 4130 aircraft tubing and
plate stock is used through out the airframe. The structural integrity of a steel cage.
Aircraft grade spruce is used in the wing spars; the extremely strong wing spar will end
the concern of any pilot examining structural integrity.
The Warner Aerocraft is one of the
strongest and most structurally sound
aeroplanes flying today. The aeroplane
uses the same type of construction
that is used on Piper Cubs, Maules,
Champs, and other classic aeroplanes
which are still going strong after 50
years of service.
The Tail Assembly: Wire braced for the strongest possible structure at the lowest
possible weight. The tail itself is made from 4130 steel tube which is MIG or optionally
TIG welded for exceptional strength. Flying cables (optional flying wires) are used to
transfer the flying load to the fuselage.
Smooth Controls: The ailerons are push pull tube activated with rod end bearings
used throughout. The rudder and elevator use aircraft cable and run over pulleys to the
tail surfaces. The control column itself has delron bearings for smooth precise control
Fiberglass: The wing tips (on the Revolution) and cowling are fiberglass parts. They
are made in our molds and greatly simplify the construction process. Our parts are the
easiest way to complete your project without the incredibly messy job of working with
Page 7 of 16
Operating Hours: The factory aeroplane has over 500 hours on it, combined with the
125 or so other aerocraft flying have a rough estimate well over 12,000 hours of flying
Factory Inventory of Parts:
Warner Aerocraft stocks for immediate delivery spruce spars, fuselages, fiberglass parts
and many other long lead items. We are committed to deliver your parts on time and
with excellent workmanship.
Cruise Speed: Greater cruising speeds are possible, but the size of the earth does not
warrant greater speeds. -Igor Sikorsky in 1934
Engines: At first glance it might appear that the ideal situation would be to start your
new airplane off with a new or zero-time engine. It seems a good idea until you begin to
detail your first flight and you are faced with conflicting requirements. It's a good idea to
ground run a new airplane and engine combination at takeoff, cruise, and descent
attitudes, and to run each tank dry in the cruise attitude in order to check for fuel flow
characteristics and for unusable fuel quantities. You should also taxi test the airplane for
ground handling characteristics, and conduct high-speed runway taxi tests to get an
initial feel for control sensitivity, and to uncover excessive out-of-trim or out-of-rig
On the other hand, the first few minutes of an engine's life are critical to its longevity.
Most over-haulers recommend minimum ground run time (5-10 minutes) prior to the first
flight and some go so far as to recommend towing the airplane to the runway to further
minimize ground time. Some suggest a low-power first flight until the rings are seated
(chrome rings on steel cylinders). Others insist on running at above 75% power for the
first 10 hours or so (I prefer and have had good results with the first method; there is
something about running a brand new engine flat out that bothers me. You should
probably use whichever method will give you the most warranty protection). In any
event, the requirements for initial test of a new airframe and those of a new engine are
in conflict.

Shown here is the completed
fuselage assembly ready for
covering. The fuselage is a fully
welded 4130 steel tube structure
and is shown here with all the
attachment brackets and fittings in
place. All the control rods and
tubes are located under the
floorboards, this leaves a clean
cockpit layout with a great
There is lots of room for
instrumentation front and rear.
Pilot and passenger sit deep into
the fuselage with air flow well over
the head. Note the large baggage
area behind the rear cockpit
accessible by a door behind the
pilots head. Deck and side
stringers are made of Spruce.
Hidden under all these feed bags
is the main spar. Load tested to 5
G's showed no sign of failure.
Page 9 of 16
Notice the outer wing panel
showing the combination box and
I-beam spar. The rear spar is
solid Spruce and the ribs are
routed from marine plywood. Note
the aileron push-rod in front of the
spar. The leading edge is I.5MM
Birch aircraft plywood.
Here you can see the outer wing
panel to center section
attachment. Note the drag and
torsion members that give the
wing its rigidity. Panel can be
easily removed in about 10
minutes for transporting by
removing 6 bolts and the aileron
push tube attachment bolt.
Here is a view of the aileron
belcrank in the outer wing panel.
All the movement works with
spherical ball rod ends. The
controls are smooth and positive.
Your First Flight:

Ground handling characteristics:
When Taxing you feel more like a nose
dragger than a tail dragger due to the
positive steering from the steer able tail
wheel. If you want to do a 180, slow to a
walk, just hit one brake, one rudder and
round you go. No more maneuvering
problems if you get stuck down a
blocked taxiway. The brakes are
effective but not grabby or noisy. There
is little danger of using too much brake
as the pressure you must apply to get in
trouble is quite high.
Takeoff characteristics: You can take
off with the nose down (my favorite, best
visibility) or three point. To take off with
the nose down apply full power evenly,
get the stick forward, get up some
speed, gradually put back pressure on
the stick, your flying! The takeoff takes
approximately 7 seconds. Crab into the
crosswind and climb out at 80 mph. With
15 KTS pure crosswind I would pay
attention but I wouldn't be worried about
it. There are no flaps to worry about on
take off, real simple.
Climb management: I usually arrive at
1000' AGL in 30 seconds, level out and
reduce power to 2100 rpm. Climb rate is
best at 80 MPH, dropping the nose
every once in a while to check for traffic
ahead. Temperatures and pressures
remain easily in the green even during
those 95 degree F Florida summers.
Cruise parameters: At 2100 RPM we
burn 5 gal per hour and get about 100
MPH. Very little trim changes are
needed with speed changes, engine
temperatures run real cool and
pressures are normal through out the
performance envelope.
Descent procedures: No special
requirements to prevent shock cooling,
typical power settings and expected
descent rates.
Slow flight characteristics: No flaps to
manage, stall is just a mush, no sharp
Landing pattern procedures:
Approach at any speed, final approach
70 MPH, crosswind techniques are
normal, use power at touchdown if you
get too slow, touchdown speeds about
50 MPH, flare techniques and landing
attitude are normal.
Landing rollout procedures: Wheel or
three point landings are easy. Rudder
and elevator have just the right authority
for a confident rollout.

Features of the Warner Line of Aerocraft.
The open cockpit design reminiscent of
the 1930's puts you back when flying
was fun. Unencumbered by air traffic
control, VOR's, GPS... You had the
trusty (if you bang on it) compass and
altimeter. Who needs those fancy
There's a short grass strip with a little
restaurant for lunch! Too high on final no
problem; she slips great and down you
go. The short take off and short landing
capability invites you down to every little
airstrip you find along the way. The main
gear just makes your landing feel great.
The aeroplane rolls out straight, with no
desire to ground loop. It's the easiest to
land tail dragger I've ever flown, you
think to yourself then you tell the folks
who watched your landing that you've
got so much experience, its like driving
a car now.
Near the beach your friend lands his
seaplane in the water to go for a little
swim. You follow him down and pull it
back into a 43mph stall into the water
behind him. You get out somewhat
dazed at the short landing to see your
airplane sinking into the waves and
remember... its not a seaplane and is
only rated for one water landing, no
takeoffs. Well you lived to fly another
day because of the slow stall speed.
Sitting in the rear fuselage you have a
good view forward, only missing a small
amount of view to the lower front where
the wing is mounted. No problem, the
aeroplane begs to roll from side to side
so you can take in the whole view.
Another day, the open air washes past
you, you smell the flowers, the fields.
Maybe buzz a cow or two maybe not if
the farmer is watching. The high rate of
climb gets you out of there in a hurry
when you see the farmer with his
