per gallon of water. Submerse the decal in the soap and water
and peel off the paper backing. Note: Even though the decals
have a "sticky-back" and are not the water transfer type,
submersing them in soap & water allows accurate positioning
and reduces air bubbles underneath.
3. Position the decals on the model where desired. Holding the
decal down, use a paper towel to wipe most of the water away.
4. Use a piece of soft balsa or something similar to
squeegee remaining water from under the decal. Apply the
rest of the decals the same way.
GET THE MODEL READY TO FLY
Check the Control Directions
1. Turn on the transmitter and receiver and center the
trims. If necessary, remove the servo arms from the servos
and reposition them so they are centered. Reinstall the
screws that hold on the servo arms.
2. With the transmitter and receiver still on, check all the
control surfaces to see if they are centered. If necessary, adjust
the clevises on the pushrods to center the control surfaces.
3. Make certain that the control surfaces respond in the
correct direction as shown in the diagram. If any of the controls
respond in the wrong direction, use the servo reversing in the
transmitter to reverse the servos connected to those controls.
Be certain the control surfaces have remained centered.
Adjust if necessary.
Set the Control Throws
Use a ruler to accurately measure and set the control throw
of each control surface as indicated in the chart that follows.
If your radio does not have dual rates, we recommend
setting the throws at the high rate setting.
Note: The throws are measured at the widest part of the
elevators, rudder and ailerons.
These are the recommended control surface throws:
High Rate
ELEVATOR:
2-1/2" [63.5mm] up
2-1/2" [63.5mm] down 3/4" [19mm] down
RUDDER:
2-1/2" [63.5mm] right
2-1/2" [63.5mm] left
AILERONS:
2" [50.8mm] up
1-1/2" [38mm] down
IMPORTANT: The YAK 55 ARF has been extensively
flown and tested to arrive at the throws at which it flies
best. Flying your model at these throws will provide you
with the greatest chance for successful first flights. If, after
you have become accustomed to the way the YAK 55
ARF flies, you would like to change the throws to suit your
taste, that is fine. However, too much control throw could
make the model difficult to control, so remember, "more is
not always better."
Balance the Model (C.G.)
More than any other factor, the C.G. (balance point) can
have the greatest effect on how a model flies, and may
determine whether or not your first flight will be
successful. If you value this model and wish to enjoy it for
many flights, DO NOT OVERLOOK THIS IMPORTANT
PROCEDURE. A model that is not properly balanced will
be unstable and possibly unflyable.
At this stage the model should be in ready-to-fly condition
with all of the systems in place including the motor,
propeller, battery, and the radio system.
1. Use a felt-tip pen or 1/8
mark the C.G. on the top of the wing on both sides of the
