Introduction
Thank you for purchasing the Yak54-F3P.
The Yak54-F3P ARF has super slow flight responsiveness so you can fly high-
alpha 3D with authority. Its carbon fiber reinforced Yak54-F3P construction
provides the solid, precise feel of a balsa profile plane without the weight. This
allows you to fly the Yak54-F3P ARF outside in windier conditions that would
keep most other profile foamies grounded. The Yak54-F3P ARF is another
exciting addition to TECH ONE's outstanding line of electric RC aircraft and
accessories.
TECH ONE uses top-quality engineering and materials in everything it makes, so
you always get the maximum level of value and fun. TECH ONE backs all of its
products with the best customer service and support in the hobby so your electric
flight experience is always a positive one.
These assembly instructions are designed to guide you through the entire
assembly process of your new airplane in the least amount of time possible. Along
the way you'll learn how to properly assemble your new airplane and also learn
tips that will help you in the future. We have listed some of our recommendations
below. Please read through them before beginning assembly.

Glue the fuselage side board onto the fuselage main board. Install the round doublers onto the pre-reserved holes on the
bottom fuselage to strengthen the joint of carbon fiber rod and
foam.
Bracing
Install the round doublers on other places. Install the doubler for the landing gear.
Cut proper length of carbon fiber rods, then install them into corresponding round
doublers. Note: The fuselage side board should be perpendicular to the fuselage main
board.
Install the round doublers, then fix the carbon fiber rods as shown to strengthen the fuselage and wing. Note: The whole plane should be
vertical, no distortion.

PRO TIP: After flying the airplane, you may want to add right
and/or down thrust to the motor. You can do this by adding
thin washers between the motor mount and the firewall.
Control System
Install the motor. Fix the wheel covers with some foam-friendly C/A.
Mount your ESC to the fuselage, using one piece of velcro. Use one piece of velcro to fix your receiver on the fuselage,
and also install your battery to the designated place on the
fuselage.

Seek Assistance
If you are new to R/C we suggest you find an experienced pilot to check out your aircraft and help you with
the first few flights.This will help prevent damage to your model and will speed up the learning process
and making your R/C experience all the more enjoyable. You can contact local R/C clubs or your dealer
to obtain the names of experienced R/C pilots who would be willingto help you with your first few flights.
Although this is an ARF (Almost-Ready-to-Fly) kit, it does have some construction features that can be
challenging to the less experienced modeler. If you encounter difficulty in any construction sequence,
please feel free to contact one of our technicians, we stand ready to provide any assistance we can.

C
Balance Point
The Center of Gravity (C/G or Balance Point) is 2.95" (75mm)
from the leading edge of the wing, measured at the center of
the wing.
WARNING For test flying and general sport flying, we suggest
you balance the airplane at the C/G recommended above. For
3D flying, you may want to experiment moving the C/G back in
small increments until you're satisfied with the result.

Exponential softens the response of the control
surfaces around neutral stick. This makes the airplane
easier to control while using such large control throws.
The Exponential values shown are given as a percent.
Please note that different brands of radio control
systems may call for + or - Expo. Please check your
transmitter's owners manual for more info.

Motor Thrust
To ensure great flight performance and to be able
to trim your airplane properly, it is critical that you
adjust the motor thrust as described. We suggest
that you add 2 degrees of down-thrust and 1
degrees of right-thrust. This can be achieved by
adding a washer or two behind the top and right
side of the motor (between the motor and the
firewall). When set properly, the trim for the
elevator and the rudder should be neutral. Fine-
tune the down-thrust and right-thrust until this trim
is achieved.
