Congratulations on your purchase of the
87”
Yak 54 ARF
. Every effort has been made to
produce a lightweight, straight, easy to assem-
ble aircraft. Because of its oversize control sur-
faces which are double beveled to allow for
extreme throws, great care must be taken in the
set-up and flying of this airplane. Quality hard-
ware components have been provided to allow
for 3D set-up while maintaining adequate
mechanical advantage to eliminate flutter. It is
your responsibility as an advanced pilot to fly
the aircraft in an intelligent manner.
THROTTLE
MANAGEMENT IS A MUST!!!!!!!
Lanier RC
has flown the
87” Yak 54 ARF
through a very
rigorous flight-testing schedule and have
stressed the airframe beyond all practical
parameters without a single failure. Lanier RC
will NOT warranty the
87” Yak 54 ARF
against
flutter due to improper set-up or excessive
speed maneuvers. having said that, we believe
you will find the
87” Yak 54 ARF
to be one of
the most responsive, in-the-grove aircraft on the
market. Just remember to use common sense
when flying this high performance machine.
We are very proud of the construction of the
87”
Yak 54 ARF
and all of our other ARF aircraft.
Each aircraft is jig built to insure a straight true
airframe. Every effort is made to build as light an
aircraft as possible. As with any professional
builder, glue is used sparingly.
Please take a
moment during assembly and run a bead of
CA or aliphatic resin into the high stress
joints that you can reach such as the landing
gear plate, servo mounting trays, wing hold
down blocks, Firewall, etc
. Also, during the
course of shipping from the manufacturer to our
facility in the United States, it is not uncommon
for the aircraft to experience several changes in
climate. This may cause the iron-on covering to
develop wrinkles. This is not a fault of the manu-
facturer. Please take a few minutes with your
heating iron and heat gun to iron down the
seams and re-shrink the covering where needed.
The results will be a beautiful aircraft with a
breathtaking finish that you will be proud to dis-
play at your flying club.
Before beginning assembly of your
87” Yak 54
ARF
, we highly recommend that you study this
manual in its entirety. You should begin planning
your radio installation based on your choice of
engine and equipment from the beginning.
Because the 87” Yak 54 ARF is intended for
those with some degree of modeling experi-
ence, every minute detail will not be cov-
ered. This is not a basic trainer. Assembly of
this aircraft will be easy for the experienced
modeler, and by following the instructions
within this manual and using the skills
you’ve gained during your modeling career
you will be able to produce a first class air-
craft.
