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 and the
carburetor 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
To ensure a successful fi rst fl ight, set up your P-40
according to the control throws specifi ed in this
manual. The throws have been determined through
actual fl ight testing and accurate record-keeping
allowing the model to perform in the manner in
which it was intended. If, after you have become
accustomed to the way the P-40 fl ies, you would
like to change the throws to suit your taste, that is
fi ne. However, too much control throw could make
the model too responsive and diffi cult to control, so
remember, “more is not always better.”
❏
1. Use a box or something similar to prop up the
bottom of the fuselage so the horizontal stabilizer and
wing will be level.
Measure the high rate elevator throw fi rst…
❏
2. Hold a ruler vertically on your workbench against
the widest part (front to back) of the trailing edge of the
elevator. Note the measurement on the ruler.
❏
3. Move the elevator up with your transmitter and
move the ruler forward so it will remain in contact with
the trailing edge. The distance the elevator moves up
from center is the “up” elevator throw. Measure the
down elevator throw the same way.
❏
4. If necessary, adjust the location of the pushrod
on the servo arm or on the elevator horn, or program
the ATVs in your transmitter to increase or decrease
the throw according to the measurements in the control
throws chart.
