 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.

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.

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 follow the instructions to 
end up with a well-built model that is straight and true.

DECISIONS 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.

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

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.

  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.
