These plans were created with the assumption that the builder has had some experience with building
R/C aircraft and installing power and control systems. Although we have attempted to be as precise and
complete as possible, there may be assembly steps that require the builder to make decisions based on
the power and control options that are installed. It is not recommended that changes in the basic design
be made. To do so would be the builders’ responsibility. This aircraft as with any R/C aircraft should be
flown in a safe environment receptive to flying R/C aircraft. Due to the fact that we have no control over
the construction or flying environment of any model produced from these plans, we will not be held
liable in any way for any consequences arising from the building or flying of any model produced from
these plans. Any model produced from these plans is to be considered “Experimental” in nature and
handled accordingly. By building and/or flying the aircraft described in this plan set you assume
complete responsibility for any and all liabilities incurred.

The WAR WING Ultimate Combat Delta is a unique aircraft capable of incredible maneuvers. It is not
recommended for beginners. It will however, offer very smooth and docile flying characteristics at low
speeds and can be flown by any pilot that has mastered basic R/C flight. At full power it becomes an
incredibly fun aircraft capable of unbelievable maneuvers. These maneuvers should be learned at
sufficient altitudes and in a safe environment until mastered.
This aircraft design is perfectly suited for R/C combat. It is extremely maneuverable but very stable and
recovers very quickly. In the event of the unthinkable, the cost to replace the airframe would be
minimal. You can build four planes out of one sheet of foam as described below and after a crash, have a
spare fuselage changed over in minutes ready for another round of combat. The Deltas are also very
durable. The prototypes have survived prop strikes and mid air collisions with little or no damage. Ones
that were damaged were easily repaired.
What You Will Need
The following items are required to complete the aircraft:
1. Propulsion system including motor, esc, battery and propeller
2. Radio control system including two standard or mini servos. (micro servos are not
recommended)
3. Fiberglass reinforced packing tape (approximately 60”)
4. Standard packing tape or “hinge” tape for hinges and to cover leading edges (optional)
5. Epoxy glue (five minute epoxy works well)
6. If you do not purchase the available assemble kit then you will need material for a motor mount
as well as control linkages, servo mounts and control horns. These items are all included in the
assembly kit offered on the website. www.warwingdelta.com.
LET’S BUILD ONE!
FUSELAGE
The fuselage is cut in three sections, horizontal wing section, vertical profile section and bottom skid.
They are constructed from Dow 1/2-in x 8-ft x 4-ft Extruded Polystyrene Insulated Sheathing that can be
purchased at most home improvement stores. (FIG 1) If it is difficult to find in your area, you may order
it online from your favorite home improvement store and have it delivered to your local store. Cost as of
this writing is approximately $14.00 for a 4’ X 8’ sheet. This price may vary according to location. One
sheet can easily provide four (4) complete Deltas at a cost of approximately $3.50 each. The board may
be cut in half lengthwise to produce two 4’ X 4’ pieces making it easier to handle. Two (2) Deltas can be
cut from each piece. (FIG 2) Your local home improvement store may cut the sheet in half for free or for
a minimal fee. This will allow it to be transported in most SUV type vehicles. Construction is much easier
if all cuts and assemblies are made before attaching the vertical fuse section to the wing section. It is
much easier to measure, cut and attach the control surfaces and other assembly steps while they lay flat
on the building surface. Use the building sequence below for the best results and ease of assembly. Be
sure to make all cuts and to assemble the Delta on a FLAT surface. Any warps or twists in either main

fuselage section will result in undesirable flight characteristics. Note: the foam board listed above is
covered with an ultra thin plastic sheeting on both sides. While it is not necessary to remove it from the
entire board, it is necessary to remove it in all areas where components will be glued. It will be
necessary to remove all of the plastic if the delta is to be painted or otherwise covered. It is
recommended however, that the film be left on the board while measuring and cutting the parts. Using
a ball point pen or fine marking pen, make all cut lines on the side containing the manufacturers printing
and cut all pieces before removing the plastic film. Cutting the foam can be accomplished by various
methods. The prototypes were cut using a 48” aluminum carpenter’s level which provided a squared
surface to slide the cutting blade on resulting in a reasonably squared edge. (FIG 3) This was
accomplished using a special blade from the food industry but a wide segmented “snap and cut” type
blade should work. Use the edge of the level to keep the blade squared at 90deg and use multiple
passes to make the cut. This is not expanded bead “cooler” type foam and cuts much easier by using
multiple shallow passes instead of trying to cut in one pass. Wire type foam cutters could be used but
would most likely make shaping the leading edges more difficult. Whatever method you choose to cut
the parts, please remember to work safely and take appropriate measures when working with sharp
blades or heat type cutters.
Tests were made with various chemicals to remove the remaining ink after removing the plastic film.
Denatured alcohol appears to work best to remove most of the ink without damaging the foam. If you
experiment with other chemicals, test on a piece of scrap foam first and of course be sure to use all
chemicals in a safe environment with adequate ventilation and free from ignition sources. It may not be
possible to remove all traces of the manufacturers markings but remember that this is a very
economical aircraft designed to be cheap, easy to build and incredibly fun to fly! This step is not
necessary if the plane is to be painted or otherwise covered. Models that were used in combat
competition were not covered, painted or modified at all. The markings were simply left as they were.
POWER/CONTROL SYSTEM
The War Wing can be flown with a wide range of power options. An Eflite Power 10 or equivilent motor
is a good choice that provides plenty of power and can be used with 3S 2200mah size lipo batteries . Use
an appropriate ESC capable of handling sustained full throttle flights when combat flying. Overall flying
weight of the prototype including a 2250mah 30C lipo battery was approximately 30 ounces. Any
suitable radio system may be used but must contain programming for elevon operation. Any standard
size servo will work fine for elevon control. Mini servos may work with good results but micro size servos
are not recommended. With this gear installed, the delta is capable of vertical launch from the ground.
We have set it on the tail and applied power for a true vertical takeoff. It will have plenty of speed and
excellent vertical performance using the suggested power and control systems. Using smaller and lighter
gear may slightly increase performance but is not necessary.
CONSTRUCTION
Wing Section:

1. Cut out the wing section according to the measurements shown on the plans. Draw
a centerline from nose to tail on the wing before cutting it out. Do not discard the
excess foam pieces. They will be used to create the bottom skid.
2. Mark and cut out the four ½” X 2” mounting tab slots from the wing center. (FIG 4)
Make the cuts as straight and square as possible as these will accept the alignment
tabs from the vertical fuse section. Try not to “overcut” the corners as this may
weaken the joint. An Xacto #11 or similar blade should work well to make these
cuts. Again, use multiple passes to make the cuts.
Note: At this time, remove the plastic film from all fuselage and control surface pieces.
Also, this would be a good time to remove the manufacturer’s markings if desired.
Complete these steps before gluing any parts or servo mounting tabs. Finally, shape the
leading edges of the wing and vertical fuse sections. A rounded cross section is the most
desirable. Take care to place the parts on a smooth surface when sanding. If this is done
on plywood or other rough surface, any imperfection in the building surface will transfer
to the foam especially if the foam is allowed to move. It is suggested that these edges be
covered with packing tape or other means to prevent damage from landings and to
avoid “hanger rash” when handling.
3. Mark and remove the elevons from the wing section. (FIG 5) Be very careful not to
“overcut” the corners on these cuts. Instead, make the main cut just short of the
corner and then use the blade following this cut to finish. Make sure to keep each
elevon in the same position that it was cut from. This can normally be accomplished
by matching up the manufacturers markings.
4. Remove approximately 1/8” inch from one end and 1/8” lengthwise from each
elevon for clearance. (Note: This step is important if you intend to perform vertical
takeoffs. The clearance will allow the elevons to function during the takeoff
maneuver as described in the “Flying” section)Remove the lengthwise material
from the trailing edge which should be the manufactured end and normally has
minor dings from handling. It is very important to make several light cuts with the
blade here or the edge of the foam will distort the blade resulting in an uneven and
unpleasant looking trailing edge.
5. Bevel the leading edge of each elevon 45 degrees and attach to the wing section.
(FIG 6) Attach the elevons to the fuselage with a good quality packing tape or hinge
tape. A strip is applied to the top surface, then the elevon is folded over and a
second strip applied to the bottom. A third strip is then applied again to the top.
This creates a very strong yet flexible hinge that has never failed to date. (FIG 7)
6. Cut out the area for the elevon servos and epoxy ply servo mounting tabs to the top
side of the wing section. While there really isn’t a top or bottom until assembled,
the Delta is more appealing if the side with the remaining manufacturers marking is
placed on the bottom. (The servo mounting tabs are shown on the bottom view on
the plans for reference only) The servo size and locations shown in the plan are for

reference only. Your cut out areas will be sized according to the servos that will be
installed. The servos were located as close as possible to the center line of the
fuselage to reduce the effect of the servos during rolls and other maneuvers. This
also served to make the receiver installation easier as no extension wires were
necessary. The foam elevons appear to be stiff enough to locate the control rods
near the inboard end as show in the assembly photos without distorting in flight.
There is no need to locate them near the center of the control surface which would
require the servos to be moved further outboard. This setup has worked very well
on all of the prototypes.
7. Attach the fiberglass reinforced packing tape to the top and bottom of wing section
at this time.
Vertical Fuse Section:
1. Cut out the fuse top section according to the measurements shown on the plans.
2. Cut and remove the areas at the bottom to create the ½”H X 2”W mounting tabs.
(FIG 8) They are colored on the plans only for clarity and are cut after the fuse
section is removed from the foam board. Make sure that the material around the
tabs are removed and not the tabs themselves. These tabs provide alignment during
assembly as well as strength for the wing section. It is advised that these tabs be
used as described. No additional means of reinforcement to the wing/fuse joint is
necessary using this method.
3. Cut out sections for the battery and receiver. The areas on the plans were according
to the original delta using a 3S 2250mah lipo battery and a standard size 72mhz
receiver. These sections may be adjusted for your flight system.
Note: While it is recommended that the receiver be installed as shown for
protection, prototypes have been constructed without the cutout area for the
battery and instead, the battery was secured to the right side of the vertical
fuselage section. Both methods have worked satisfactorily. Whichever method is
chosen, be sure to use a retaining strap such as the hook and loop type strap to
keep the battery in place. DO NOT rely solely on hook and loop type fasteners
attached to the fuselage to secure the battery. The roll rate and violent maneuvers
this aircraft is capable of doing will almost certainly cause the battery to depart
from the plane if no physical means to secure it are used.
4. Remove the rudder from the vertical fuse section. (FIG 9) NOTE: It has been
determined that while a rudder will allow a bit more maneuverability it is not
necessary and only requires more euipment to be added. This is especially true if
your model will be used for combat flying. If you wish to add rudder control by all
means proceed to step 5.
5. Remove approximately 1/8” from one end and 1/8” lengthwise from the rudder for
clearance.

6. Bevel the leading edge of the rudder and attach to the fuse section. (FIG 10)These
were attached on the original using a good quality packing tape as described in the
wing section assembly notes.
7. Cut out the area for the rudder servo and epoxy ply servo mounting tabs. The servo
size and locations shown in the plan are for reference only. Your cut out areas will
be according to the servos that will be installed. Standard size servos were used on
the original. Be sure to remove any “hinge” tape from an area where mounting tabs
will be glued.
8. Attach servo horn mounting plates to the control surfaces according to the location
of the servos installed. Install control horns. Remove any “hinge” tape from the area
to be epoxied.
Assembly:
1. Dry fit the fuselage sections ensuring that the alignment tabs fit properly.
2. Epoxy the vertical fuselage section to the bottom wing section using the tabs for
alignment. Be sure to align the fuse section at 90 degrees to the wing section. Mark
the area where the receiver will mount corresponding to the cut out made earlier
on the vertical fuse section and do not apply glue to that area. Also, if you have
purhcased the available motor mount or assembly kit, do not apply any glue to the
front area approximately two inches back from the front edge of the fuselage. The
motor mount must slide onto this area and will secure the front section when glued
in place.
3. Cut and install bottom skid piece under wing section. (FIG 11) Use the alignment
devices included with the building materials pack to mount it as straight and as
perpendicular to the fuse bottom as possible. Pay particular attention to the
alignment of the front edge of the skid as the motor mount will slide over the skid
when installed. If you purchased an assembly kit, an alignment tool is provided to
aid in attaching the bottom skid.
4. Assemble and epoxy the motor mount to the front of the plane. Simply slide the
assembled mount over the front of the fuse until it stops. It will align itself using the
fuselage as a guide.
5. Figure (12) shows a completed fuselage ready for installation of the power and
control systems.
6. The remaining assembly includes installing the power system, radio system and
control linkages. These items will vary according to the type of equipment used and
the remaining procedures will be left to the builder. The balance point shown on the
plan is approximate and was determined using the equipment listed. This position
has proven to work well but if you choose to experiment with the CG to suit your
flying abilities, please make minor changes until the position that you are
comfortable with is reached.

FLYING
When all components have been installed and the Delta is ready to fly the following guidelines are
recommended.
1. Dual rates are recommended. Use low rates for taking off. Performing a takeoff with high rates
has at times caused excitement to some spectators. You are advised to use low rates during
launch. Use high rates for maximum performance and for landing. High rates are recommended
for landing to allow for the slowest and most controlled landing. It is not necessary to make a
speedy approach and flare such as with a typical R/C plane. Instead, approach the landing area
at low level with minimum speed, cut the throttle and input full up elevator just before touching
down which should produce a high angle flare and allow the Delta to set down tail first and flop
on the nose. This method has saved many propellers.
2. Set low rates so that the edges of the control surfaces are even with the opposite fuselage
surface. Example: set the bottom of elevon even with top of wing. This setting should produce
very controllable and docile flight characteristics.
3. Set high rates as desired. The prototypes were set for maximum throw with very desirable
results. For highly experienced pilots –more is better. You can always program in expo if
necessary.
4. The War Wing Delta can easily be hand launched by holding the top of the vertical fuse or the
lower skid. It does not need to be thrown. Simply let it fly out of your hand. (assuming that the
recommended power system or equivalent was installed) If performing a vertical takeoff, a small
bit of down elevator will usually be necessary as it has a slight tendency to loop upon leaving the
ground due to the weight of the battery making it top heavy. You should input a small amount
of down elevator before lifting off. Try this first in a safe environment free of onlookers. If it
becomes uncontrollable, simply cut the throttle and regain control. It will recover very easily
and resume flight with minimum power. Again, use low rates for vertical takeoff maneuvers as
well as hand launches.
5. The prototypes have been subjected to incredible maneuvers. The Delta will perform loops
almost within its own length. It rolls very fast on high rates. The more it is flown, the more you
will discover the crazy maneuvers it will do. The Delta will achieve a noticeable top speed and
climb out of sight vertically very quickly. It will also hover with almost no wind and is very docile
and stable when flown at low speeds. The flight characteristics are only limited by your
imagination. Feel free to experiment as the Delta will, if built as indicated, take almost any
abuse that you can give it. None have been lost due to structural failure except prototype
number one which was built very differently and served to discover weaknesses that were
redesigned resulting in the current model. If you have any questions, comments or suggestions,
please feel free to contact us. Fly safe and HAVE FUN!!
