TURBO RAVEN. Instruction Manual
INTRODUCTION.
Thank you for choosing the TURBO RAVEN ARTF by SEAGULL MODELS. The TURBO
RAVEN was designed with the intermediate/advanced sport scale in mind. It is a semi scale
airplane which is easy to fly and quick to assemble. The airframe is conventionally built using balsa,
plywood to make it stronger than the average ARTF , yet the design allows the aeroplane to be kept
light. You will find that most of the work has been done for you already. The motor mount has been
fitted and the hinges are pre-installed . Flying the TURBO RAVEN is simply a joy.
This instruction manual is designed to help you build a great flying aeroplane. Please read this
manual thoroughly before starting assembly of your TURBO RAVEN. Use the parts listing below to
identify all parts.
WARNING.
Please be aware that this aeroplane is not a toy and if assembled or used incorrectly it
is capable of causing injury to people or property. WHEN YOU FLY THIS AEROPLANE YOU
ASSUME ALL RISK & RESPONSIBILITY.
If you are inexperienced with basic R/C flight we strongly recommend you contact your R/C
supplier and join your local R/C Model Flying Club. R/C Model Flying Clubs offer a variety of training
procedures designed to help the new pilot on his way to successful R/C flight. They will also be able
to advise on any insurance and safety regulations that may apply.

hinges are glued in place, a 1/64” gap or less
will be maintained throughout the lengh of the

hinge, making sure that the C/A penetrates into
both the aileron and wing panel.
6) Using C/A remover/debonder and a
paper towel, remove any excess C/A glue that
may have accumulated on the wing or in the
aileron hinge area.
7) Repeat this process with the other wing
panel, securely hinging the aileron in place.
8) After both ailerons are securely hinged,
firmly grasp the wing panel and aileron to
make sure the hinges are securely glued and
cannot be pulled out. Do this by carefully
applying medium pressure, trying to separate
the aileron from the wing panel. Use caution
not to crush the wing structure.
Note: Work the aileron up and down several

times to “work in” the hinges and check
for proper movement.

Accurately mark the balance point on the top

of the wing on both sides of the fuselage. The
balance point is located 145 mm back from
the leading edge of the wing at the wing root.
This is the balance point at which your model
should balance for your first flights. Later, you

up to 10mm forward or back to change the
flying characteristics. Moving the balance
forward may improve the smoothness and
arrow- like tracking, but it may then require
more speed for take off and make it more
difficult to slow down for landing. Moving the
balance aft makes the model more agile with
a lighter and snappier ”feel”. In any case,please

With the wing attached to the fuselage, all
parts of the model installed ( ready to fly), and
empty fuel tanks, hold the model at the
marked balance point with the stabilizer level.
Lift the model. If the tail drops when you lift,
the model is “tail heavy” and you must add
weight* to the nose. If the nose drops, it is
“nose heavy” and you must add weight* to the
tail to balance.
*If possible, first attempt to balance the model

by changing the position of the receiver battery
and receiver. If you are unable to obtain good
balance by doing so, then it will be necessary
to add weight to the nose or tail to achieve the
proper balance point.
