Additional surfaces are added at the end of the propeller blades to prevent peeling off during printing. These surfaces must be removed after printing. Assembly tip: Clean parts thoroughly, removing all threads and printing imperfections. Ensure that the axis and rotor rotate freely in the hander. Use string with a diameter of less than one millimetre and a length of about 80cm. When using, pass the string through the hole in the propeller shaft, then insert the shaft into the rotor, passing the string through the slot in the shaft. Wrap the string around the rotor in the direction of the arrow. Then insert the rotor into the hander. Then pull the string with the puller.
