Tachometer
The tachometer system is connected to the Rotax sensor, the Rotax manual should be
consulted for maintenance instructions.
Propeller
The Skypper 582 propeller is a glass and carbon fiber composite, three- or four-bladed
Arplast propeller. It is equipped with the tool necessary to check or change the pitch.
The blades are made by pair and balanced at the factory. It is not advised to modify their
weight, the adhesive label “Arplast” is part of the balancing, and the adhesive discs stuck
to the rings display balancing information and must not be removed.
If the engine is to be rotated at any time, it should only be rotated in the same
direction as it runs. Rotating the engine against the way that it runs may introduce air
into the oil supply and cause damage to the engine.
When working on the propeller remove the spark plug leads from the spark plugs.
Ecoprop Propeller Assembly
Lubricate lightly the metallic rings of the blades in order to prevent corrosion and to ease
rotation while adjusting the pitch.
Place the blades into the sockets of the unmarked half of the hub opposite of the engine.
Cover with the other half of the hub while respecting the position of the angular marks.
Set the bolts M6 and the lock nuts of the blades, but without tightening.
Use the 6 bolts CHC M8x100 to mount the propeller on the engine flange assembly
without tightening fully so that the blades can still rotate. (Figure 6-23)

Pitch Adjustment
Position the adjusting tool (R105850) as shown (Figure 6-24 and Figure 6-25). Adjust the
pitch on all blades.
Warning: a space between the wedge and the blade area represents +/- 0.1° and may
induce vibrations while operating.
