In 1946 a group of Lockheed employees, including Tony
LeVier, designed and built three Cosmic Winds. These very
small, single seat racers were designed to compete in the
1947 Goodyear Trophy Race, in Cleveland Ohio. They came
in 3rd and 4th in the Race. However, in 1964 one of the three
planes called the Ballerina did win the Kings Cup Race in
the UK. One of the three original planes is now in the EAA
AirVenture Museum in Oshkosh, Wisconsin. Great Planes
has taken the great looks of the full scale Cosmic Wind and
reduced it down to a light weight, electric powered ARF. The
plane is small enough that it can be placed in the back seat
of most cars but large and quick enough to still enjoy fl ying
at the local fl ying fi eld. So if you are ready to fl y a piece of
racing history, let’s get started building.

Academy of Model Aeronautics
We urge you to join the AMA (Academy of Model Aeronautics)
and a local R/C club. The AMA is the governing body of model
aviation and membership is required to fl y at AMA clubs.
Though joining the AMA provides many benefi ts, one of the
primary reasons to join is liability protection. Coverage is not
limited to fl ying at contests or on the club fi eld. It even applies
to fl ying at public demonstrations and air shows. Failure to
comply with the Safety Code (excerpts printed in the back of
the manual) may endanger insurance coverage. Additionally,
training programs and instructors are available at AMA club
sites to help you get started the right way. There are over 2,500
AMA chartered clubs across the country. Contact the AMA at
the address or toll-free phone number below:

IMPORTANT!!! Two of the most important things you can
do to preserve the radio controlled aircraft hobby are to avoid
fl ying near full-scale aircraft and avoid fl ying near or over
groups of people.
SAFETY PRE CAUTION S
PROTECT YOUR MODEL, YOURSELF & OTHERS…
FOLLOW THESE IMPORTANT SAFETY PRECAUTIONS
1. Your “Cosmic Wind EP” should not be considered a toy, but
rather a sophisticated, working model that functions very
much like a full-size airplane. Because of its performance
capabilities, the “Cosmic Wind EP”, if not assembled and
operated correctly, could possibly cause injury to yourself
or spectators and damage to property.
2
2. You must assemble the model according to the instructions. Do not alter or modify the model, as doing so
may result in an unsafe or unfl yable model. In a few cases
the instructions may differ slightly from the photos. In those
instances the written instructions should be considered
as correct.
3. You must take time to build straight, true and strong.
4. You must use an R/C radio system that is in fi rst-class
condition, and a correctly sized motor and components
throughout the building process.
5. You must correctly install all R/C and other components
so that the model operates correctly on the ground and
in the air.
6. You must check the operation of the model before every
fl ight to insure that all equipment is operating and that the
model has remained structurally sound. Be sure to check
clevises or other connectors often and replace them if they
show any signs of wear or fatigue.
7. If you are not an experienced pilot or have not fl own this
type of model before, we recommend that you get the
assistance of an experienced pilot in your R/C club for
your fi rst fl ights. If you’re not a member of a club, your
local hobby shop has information about clubs in your area
whose membership includes experienced pilots.
8. WARNING: The fuselage and wheel pants included in this
kit are made of fi berglass, the fi bers of which may cause
eye, skin and respiratory tract irritation. Never blow into a
part (wheel pant) to remove fi berglass dust, as the dust
will blow back into your eyes. Always wear safety goggles,
a particle mask and rubber gloves when grinding, drilling
and sanding fi berglass parts. Vacuum the parts and the
work area thoroughly after working with fi berglass parts.

Motor Recommendations
The Cosmic Wind ARF comes with a mounting plate for the
ElectriFly® RimFire brushless outrunner motor. The motor has
been tested with this plane and works well.
❍ElectriFly RimFire .10 Brushless Outrunner Motor
[GPMG4595]
Propeller
If using the recommended RimFire Brushless Outrunner
Motor, we recommend the APC 8×8E electric propeller
[APCQ4116] for good speed performance. For better vertical
performance, with a slight reduction in speed, use the APC
9×7.5E [APCQ4119].
Electronic Speed Control
A brushless ESC (electronic speed control) is required for
the recommended motor set-up. We recommend using the
ElectriFly Silver Series SS-35A Brushless ESC [GPMM1830].
Flight Battery
We, as the kit manufacturer, provide you with a top quality,
thoroughly tested kit and instructions, but ultimately the
quality and fl yability of your fi nished model depends
on how you build it; therefore, we cannot in any way
guarantee the performance of your completed model,
and no representations are expressed or implied as to the
performance or safety of your completed model.
Remember: Take your time and f ollow the instructions to
end up with a well-built model that is straight and true.
DECISI ONS YOU MUST MAKE
This is a partial list of items required to fi nish the “Cosmic
Wind EP” that may require planning or decision making before
starting to build.
Radio Equipment
A 4-channel radio system with four micro servos and receiver
are required for this plane. The servos and receiver shown
in the manual are Futaba® S3114 Micro High Torque Servo
and the Futaba R617FS receiver.
Transmitter Receiver
4-channel 7-channel [FUTL7627]
The Cosmic Wind EP ARF has been fl own with the ElectriFly
Power Series 11.1V 1500mAh LiPo battery and the Flight
Power EON-X™ Lite 11.1V 1600mAh LiPo battery packs. In
our testing we found that if the APC 8×8E propeller was used
with the recommended motor, the static current draw was
approximately 24 amps.

discharge w/balance plug [GPMP0515]
❍FlightPower® EON-X Lite LiPo 1600mAh 11.1V 25C
discharge w/balance plug [FPWP4146]
Recommended Charger
A LiPo compatible charger is required to charge LiPo batteries.
The Great Planes ElectriFly PolyCharge4™ is designed for
LiPo packs only; however, it is able to charge four LiPo packs
simultaneously. The ElectriFly Triton 2™ and AC/DC Triton2 EQ
chargers will only charge one pack at a time, but are capable
of charging NiCd, NiMH, Pb acid and LiPo batteries.

OR
❍Great Planes AC/DC Triton2 EQ Charger/Balancer
(GPMM3156)
Throughout the life of a LiPo battery, the individual cells
located inside the battery may become unbalanced. These
unbalanced cells can shorten the life of the battery or cause
it to malfunction. For this reason, it is always recommended
that a cell balancer be used when charging LiPo batteries.
The ElectriFly Equinox™ is a cell balancer that may be used
with any LiPo charger and is capable of maintaining the cell
balance of the battery. Note: The AC/DC Triton2 EQ does not
require a cell balancer.
This is the list of adhesives and building supplies required
to finish the Cosmic Wind EP. Order numbers are provided
in parentheses.

IMPORTANT BUILDING N OTES
● There are two types of screws used in this kit:
Sheet Metal Screws are designated by a number and a
length. For example #6 × 3/4" [19mm].
This is a number six screw
that is 3/4" [19mm] long.
Machine Screws are designated by a number, threads
per inch, and a length. For example
4-40 × 3/4" [19mm].
This is a number four screw
that is 3/4" [19mm] long with
forty threads per inch.
● When you see the termtest fi t in the instructions, it means
that you should fi rst position the part on the assembly
without using any glue, then slightly modify or custom fi t
the part as necessary for the best fi t.
●Whenever the term glue is written you should rely upon
your experience to decide what type of glue to use. When
a specifi c type of adhesive works best for that step, the
instructions will make a recommendation.
●We recommend 30-minute epoxy only, because you will
need the working time to position the part correctly and
the additional strength.
●Photos and sketches are placed before the step they refer
to. Frequently you can study photos in following steps to
get another view of the same parts.
●The Cosmic Wind EP is factory-covered with Top Flite®
MonoKote® fi lm. Should repairs ever be required, MonoKote
can be patched with additional MonoKote purchased
separately. MonoKote is packaged in six-foot rolls, but
some hobby shops also sell it by the foot. If only a small
piece of MonoKote is needed for a minor patch, perhaps a
fellow modeler would give you some. MonoKote is applied
with a model airplane covering iron, but in an emergency a
regular iron could be used. A roll of MonoKote includes full
instructions for application. Following are the colors used
on this model and order numbers for six foot rolls.
Missile Red - TOPQ0201
Jet White - TOPQ0204

PREPARATIONS
1. If you have not done so already, remove the major
❏
parts of the kit from the box and inspect for damage. If any
parts are damaged or missing, contact Product Support at
the address or telephone number listed in the “Kit Inspection”
section on page 4.
2. Check the covering on the wing, stabilizer and rudder.
❏
Use a covering iron with a covering sock on medium heat to
tighten the covering if necessary. Apply pressure over sheeted
areas to thoroughly bond the covering to the wood.
ASSEMBLE THE WING
3. Mix together ½ oz. [15cc] of 30-minute epoxy. Coat the
❏
inside of wing joiner cavity in both of the wing halves. Apply
epoxy to half of the wing joiner and insert it into one of the
wing halves. Apply epoxy to the other half of the wing joiner
and the root rib of both wing halves. Join the second wing
half to the fi rst. Wipe off any excess epoxy with a paper towel
dampened with denatured alcohol. Hold the two wing halves
together with masking tape until the epoxy has cured.
4. Insert the two ¼" × 1" [6 × 25 mm] wood wing dowels
❏
in the leading edge of the wing. Glue the wing dowels to the
wing with thin CA glue.
Join the Wing Halves
1. Test fi t the hardwood wing joiner in the two wing halves.
❏
Note that one edge of the wing joiner is fl at and the other edge
is tapered. The fl at edge is positioned towards the top of the
wing. With the wing joiner properly installed both wing tips
should be off of the table. Check that there is no gap between
the two wing halves at the wing root.
5. Remove the covering from the two wing bolt holes in
❏
the wing and the wing bolt plate. Position the wing bolt plate
on the bottom of the wing and insert the two 3×18mm wing
bolts to hold it in position.
2. Insert the 3 × 15mm alignment pin half way into the root
❏
rib of one wing half. Use thin CA to glue it in position.
6. Use a fi ne line marker to mark the outline of the wing bolt
❏
plate on the bottom of the wing. Remove the wing bolt plate.
Using a sharp hobby knife cut and remove the covering from
the wing, inside the outline of the wing bolt plate. Do not cut
the balsa wing sheeting.
7. Glue the wing bolt plate to the bottom of the wing using
❏
the wing bolts to align the wing bolt plate with the wing.
