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.

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.
