Electronics (not included in the kit) / The Duct
Attach the control rod to the right rudder horn and the servo horn. Place the servo between the mar-
kings on the upper shell. Position the servo so that the rudders are exactly lengthways when the
servo is in center position. In this position glue the servo in place.
By using the template draw the duct and the cover onto the 0.5 mm ABS sheet and cut them out.
Here, too, you may cut the material with a razor blade knife and then break it off. Pre-drill the four
holes in the duct material. Mount the duct with 4 Allen Head screws to the upper shell and secure
them at the underside with washers and self locking nuts.
Cut 8 holes into the surrounding rim of the upper shell for the tapered screws. Later they will connect
the lower with the upper shell.

Mount the hover and pusher motors to their respective motor mounts. Press the hover propeller to
the motor shaft as shown in the picture. Depending on the motor you may have to widen the drill hole
in the propeller hub. The conical end of the propeller hub has to point towards the motor. Mount the
large propeller to the pusher motor.
