Final Assembly
Plug the aileron servo connector into the connector marked
“aileron” located in the fuselage. This will connect the aileron
servo in the wing to the aileron channel of your receiver.
Temporarily attach the wing to the fuselage by stretching a rubber
band from wing hold-down dowels starting at the leading edge of
the wing back to the trailing edge of the wing. For now, use just
two rubber bands to mount the wing in position.

Pre-flight Checks
The correct servo directions are pre-adjusted, but it’s a good idea
to confirm the correct direction. After charging the transmitter and
receiver batteries per the instruction included with the radio, turn
on the transmitter and airplane and check that the controls are
moving in the correct direction, as per the illustration below.
Moving the right stick down should cause the elevator to move
upward. Moving the right stick to the right should move the right
aileron up (looking from the back of the airplane). Moving the left
stick to the right should move the rudder to the right. Now, check
the throttle. Look into the carburetor. With the throttle (left stick)
in the upper position, the carburetor should be fully open.
If any of the above controls are working in the wrong direction,
consult the 421
EX
radio manual on servo reversing.
