DO NOT LAMINATE THE AREA OF THE TUNNEL TO WHICH THE ELECTRICAL MOTOR
SUPPORT WILL BE FIXED.
3. COMPOSITE MOTOR SUPPORT AND DRIVE LEG
The motor support and the drive leg must be centered in the tunnel.
Locate and mark the intended position of the holes for the fixing screws and the leg hub.
You can use the motor support and the leg’s gasket to mark these holes.
In some cases it will be easier to mark and drill these holes BEFORE laminating the
tunnel.
After drilling, use the gasket to verify the holes’ axes and adjust them with a round file
where necessary.
These holes must be completely clean before inserting the screws.
Position the leg, the gasket (between the leg and the tunnel) and the motor support,
and then tighten the the two screws alternatively. Finally, mount the propeller(s) to control
the general alignment.
If the general set-up is correct, remove the propeller(s),the leg and the gasket.
Apply a thin coating of silicon grease or sealing compound to both sides of the gasket
(this must be resistant to hydrocarbons and water). Re-assemble all parts as before,
positioning and then tightening the two 8mm
∅ screws alternatively using a 5.5mm Allen
key (maximum torque: 25 Nm).
Check that the propellers rotate freely, without resistance or friction.
It is imperative that the holes and the screws remain free of sealing compound,
otherwise there is a risk of an incorrect assembly of the parts.
Caution: do not use graphite grease.
NOTE:
The composite drive leg:
• is pre-filled with oil and sealed for life
• does not require anodes
• must not be disasembled, even partially (exclusion waranty)
