- C.G. (Center of Gravity)
- 6 3/4in
or 17.5cm from front
nose of plane towards the rear.
-
C.G. is
critical on this wing otherwise it flies like crap. (i.e. not good).
- Use a Nickel in the battery bay as weight to fine
tune your plane to find you balance,
then cut the battery tray foam and move your battery accordingly.
- Core
- What type of
foam is it?
-
EPP
Epran 1.9lbs Foam
(Expanded
PolyPropylene)
- My wing cracked in half because I let my friend
fly it full throttle into the ground. What do I do?
- Use Hot Glue for all repairs. If your glue sucks
then use Gorilla Glue to mend the wing together.
- Test
your hot glue on a small section to make sure it
does not melt. We use the Dremel Glue Gun.

- Dimensions:
- Width: 31 inches.
- Height: 1.5 inches (Body), 3 inches (Fins).
- Depth: 16 inches.
- Weight: 9 oz
- Fins
- We use white EPP Epran 1.9lbs Foam, 10mm
thickness.
- The fins are designed to drag the wing tips to
maintain a straight flight path
- The "V" design is meant to cup the wind or generate
a high angle surface if the wing gets sideways during
slow flight which virtually eliminate tip stalls.
- Let's see how long it takes before someone bites my
design. hmm...
- Routed battery bay
- The battery bay can be moved or cut to accommodate a different batteries
as long as you achieve your center of gravity for the
plane.
-
Routed servo bay
- The Servo Bays are cut deep so
the servo horn does not protrude above the surface of
the wing. This is designed to avoid stripping the servos
during combat.
-
Routed receiver/ESC
bay
- Engine mount
- What type of
wood is it made of?
-
Cherry Wood.
- "-2" degree down pitch.
- The engine mount has a -2 degree down pitch to
counteract the lift properties of the wing at full
throttle.
- What of screws
do I use?
-
2 X 1/4" The
key is the number "2".
- These can be bought at you local Hobby Shop.
- Ailerons
-
EPP
Epran 1.9lbs Foam
(Expanded
PolyPropylene)
- A thin sheet is cut, sprayed with 3M 77 Adhesive,
layered with Ultracoat and then heat set in place for a
ridge aileron.
- This material can bend and still maination its shape
after a hit.
- Apply heat to get rid of wrinkle that my occur over
time
-
Control horn linkage
to ailerons
- Make sure you do not have any slope or
play in you connection from the control horn the control
rods.
- If you do have play
the wing will hunt up and down making the plane not fly
well and have a unpredictable flight path.
-
Nine Gram servos
- We use the
Hextronix 9 gram servo.
-
-
ESC 12Amp (Electronic
Speed Controller)
- You can use any 12 amp or higher electronic speed controller.
- Lipo
Battery
- use can use any 1000mAh Lipo battery.
- Battery flight time last around 10 to 12 minutes.
- Five inch propeller
- What type of Propeller do you
use. It is a GWS
EP-5043
Propeller.
Picture1,
Picture2
- Do not use a 6" propeller or higher as it will put
too much strain on the motor and it will get too hot.
- If you have a weak or old battery and your engine keeps
cutting out in mid flight then you will need to go to a
5030 or lower to reduce current draw. The ESC will sense
the battery can not handle the output required to
energize the motor therefore it will shut down the motor
but your servos will remain active.
- 25gram
Brushless Outrunner Motor
- We use a
Hextronix
and Turnigy motors. Also know as Old blue that have
12 stators with a high KV winding (3000kv)
- The BattleWing should will fly out of your hands and
climb vertical (at a modest rate) on a 2cell battery.
Example of
20g motor and the 25g motor.
-
Prop saver rubber bands
- A black
O-Ring
comes with the motor but it will break in a week or two. For a
replacement we use the yellow/orange surgical tubing which last a
long time.
- Alternatives are
Orthodontic
Elastics or Hair rubber band used to make girls pony tails but you
will need to use 3 bands at one time. You can also use large fuel tubing
for gas planes
.
- Mounting and
testing
- Reinforcement
tape
- You must lay a layer of smeared hot glue on the foam
first if you want the tape to adhere.
- Flex in the wing causing the tape to buckle and create air pockets.
This dries out the tape and to loose adhesion. Using hot glue as a
platform and to seal the edges significantly increases the life of the
tape.
