Assembly

Again you follow the original instructions of the Multiplex Funjet. This mentions only the differences.

Enhance the servo cable by adding extra cable to have 28cm in total, secure the cable with heat shrink tube if you solder. Remove the black plastic case of the plug and thread the three golden plugs from the outside through the 5mm servo channels to the fuselage. Re-attach the black plug in the fuselage in the correct order. Install the servo and mechanics as described in the manual.

Add a male BEC cable for the Umarim power supply to the speed controller battery input connector and extend the total length to 42cm. Attach the motor to the speed controller. Mount the speed controller at the back of the fuselage.

Install the propeller on the prop saver. Make sure you keep the rubber in a good condition. Replace them early. Put black duct tape over the edge of the glass so that the glass fibres can not hurt. Add the same tape over the leading edge of the wing.
