3. Drill 1/16" [1.6mm]
holes through the bot-
tom of the pilot 1-1/8"
[29mm] apart to align
with the holes in the
bottom of the cockpit
fl oor for the pilot mount-
ing screws.
4. Mount the pilot to the cockpit fl oor with two #2 x 1/4"
[6mm] or #2 x 1/2" [12mm] screws and #2 washers
(not included).
GET THE MODEL READY TO FLY
SET THE CONTROL THROWS
1. If measuring the control throws in degrees, follow the
instructions that came with your throw measuring tool to set
the throws according to the measurements that follow. If
using a ruler, proceed with the following instructions.
2. Set the throws on the elevator fi rst. Use a small box or
something similar to prop up the bottom of the fuselage until
the wings and horizontal stabilizer are level.
3. With the transmitter and receiver on and the elevator
centered, hold a ruler up to the trailing edge of the elevator
at the
widest
part (nearest the fuselage).
4. Use the transmitter to move the elevator up and move
the ruler forward so it will still be touching the trailing edge.
The distance the elevator moves is the “up elevator” control
throw. Use the endpoint adjustment in your transmitter
or move the screw-lock pushrod connector in the elevator
servo arm to a new hole to increase or decrease the throw
as necessary.
5. Measure and set the up and down and left and right
control throws for all of the control surfaces. If your radio does
not have dual rates, we recommend setting the throws at the
high rate setting.
NOTE
: The elevator and rudder throws are
measured at the
widest part
.

IMPORTANT:
The Carl Goldberg Chipmunk 400 ARF
has been extensively fl own and tested to arrive at the throws
at which it fl ies best. Flying your model at these throws
will provide you with the greatest chance for successful
fi rst fl ights. If, after you have become accustomed to the
way the Chipmunk 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 diffi cult to control, so
remember, “more is not always better.”
