Step 27

Center the throttle stick and trim with both the
receiver and transmitter on. Install the throttle servo
arm in the neutral position.

Step 28

Move the servo to the throttle closed position using
the radio system. Manually move the throttle arm on
the carburetor to the closed position. Use a 3mm set
screw to secure the throttle pushrod wire.

Step 29

Check the movement of the throttle to verify
there is no binding at either low or high throttle.
If there is, make the necessary adjustment to
eliminate any binding. Install the throttle servo
arm screw when complete.

Step 30

Use scrap wood to make a brace for the throttle
pushrod tube near the servo as shown.

Step 31

Install the tail wheel using a 3/32" wheel collar and
3mm set screw.
