hexagon screw, so that the propmechanism will not loosen itself through vibration. This is the state in
which the ORBIS is delivered.
Verify the fixing of the prop mechanism by trying to turn the prop mechanism while
holding the
motor crankcase.

Pay attention to the warnings for the prop mechanism in chapter 3.
1.15. Installation of a fuselage cover
The cast that was made in section 1.5. is now adapted to the form below. Be aware that you have to
be able to extend and retract the ORBIS to find the right position and form for the cover. The front
edge (1.16.1.-36 red line) of the cover depends on the form of the fuselage. If the fuselage is narrow
the cover must be smaller. Looking from the side the backrim of the cover (1.16.1.-37) may not
protrude the backside of the support arms.
Graphic 1.16.1. Installation of a fuselage cover
Consider the curvature of the cover since the figure above is a top view. Do not glue the cover
immediately between the SLS support arms. Firstly attach the cover with adhesive tape and verify that
the cover does not touch the fuselage wall or the levers of the end switches while the SLS is
retracting.
