3. You must take time to build straight, true and strong.
4. You must correctly install all R/C and other components so
that the model operates correctly on the ground and in the air.
5. You must check the operation of the model before every
flight 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.
6. If you are not an experienced pilot or have not flown this
type of model before, we recommend that you get the
assistance of an experienced pilot in your R/C club for your
first flights. 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.
7. While this kit has been flight tested to exceed normal use,
if the plane will be used for extremely high-stress flying,
such as racing, or if a motor larger than one in the
recommended range is used, the modeler is responsible for
taking steps to reinforce the high-stress points and/or
substituting hardware more suitable for the increased stress.
Remember: Take your time and follow the instructions to
end up with a well-built model that is straight and true.
This is a partial list of items required to finish the YAK 54 EP
3D ARF that may require planning or decision making before
starting to build. Order numbers are provided in parentheses.
A 4-channel radio system with four micro servos and a micro
receiver are required for this plane. The servos and receiver
shown in the manual are Futaba
®
S3110 micro servos and
the Futaba R114F micro receiver. Two 6" [150mm] servo
extensions and a Y-harness are also required. Order
numbers for these items are provided below.

[7.7g] (FUTM0046)
•
Futaba R114F FM Micro Receiver
(Low Band – FUTL0442, High Band – FUTL0443)
•
Futaba FM Single Conversion Short Crystal
(Low Band – FUTL62**, High Band – FUTL63**)
•
(2) Futaba C-25 Extension Slim Wire
6" [152mm] (FUTM4506)
•
Futaba 6" [152mm] Dual Servo Extension
J (FUTM4130)
The YAK 54 EP 3D ARF comes with a mounting box that will
accommodate either a brushless in-runner motor with gear-
drive or a brushless out-runner motor. The motors that have
been tested and perform well in this plane are listed below.
If using the in-runner motor with gear-drive, be sure to install
the 11T pinion that is included with the gear-drive to achieve
a gear ratio of 4.5:1.

Great Planes Ammo
™
24-33-4040kV Brushless
In-runner Motor (GPMG5165)
Great Planes Gear-Drive 24mm Motors (GPMG0505)
•
Great Planes RimFire
™
35-30-950kV Brushless
Out-runner Motor (GPMG4590)
Note: Motors from other manufacturers may work with the
YAK 54 EP 3D ARF. However, the included firewall pieces
are designed to work specifically with the Great Planes
motors listed.
If using the Ammo Brushless In-runner motor with 4.5:1
gearbox or the RimFire Brushless Out-runner motor, you will
need a 11x4.5 Slo-Flyer Electric Propeller (GPMQ6695).
A Brushless ESC (electronic speed control) is required for
this plane. We recommend using the Great Planes Silver
Series 25A Brushless ESC 5V/2A BEC (GPMM1820).
The YAK 54 EP 3D ARF has been tested with 11.1V LiPo
packs ranging from 1250mAh to 2100mAh. Order numbers
are provided for packs of this size. The lighter 1250mAh
pack is suggested for maximum performance. A 20C
discharge pack is necessary for best performance.

DECISIONS YOU MUST MAKE
We, as the kit manufacturer, provide you with a top quality,
thoroughly tested kit and instructions, but ultimately the
quality and flyability of your finished 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.
