DO NOT LAMINATE THE AREA OF THE TUNNEL TO WHICH THE ELECTRICAL MOTOR 
SUPPORT WILL BE FIXED. 
3.  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 12mm ∅ screws alternatively, using a 8mm Allen 
key, (maximum torque: 50Nm). 
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.
