Safety and helix design


   The security criteria in the project has been carefully considered. The helix is made in a special design avoiding that the centrifugal force produces the loss of a blade. On the other hand, the gear system uses a friction gear avoiding any possible personal damages in the event of touching the rotating helix. This system protects the motor too.

   The helix is a standard 3 blades 120º design centered in an axle. The blades are secured by a little 2u beam (1X2 W/Cross And Hole) that fixes it to a  doubled Technic Lever unit (3X120) acting as a centre support. This configuration ensures that no blade cannot be ejected by the centrifugal force.

   The front end is decorative and can be eventually replaced by a conical shaped element.
