Definitely on my list. The dark art of helicopter recovery has always been shrouded in mystery for me. Then again, so has the dark art of hitting the bowl, yet I persist.

John,
Very cool! If you're allowed, could you post some pictures of the hub. Are the blades set at a fixed angle? Also, why was this fun to design? Steve |

It looks like the hinge/hub is made from laser cut fiberboard - you can the parts in the photo on Estes website. Along with what appears to be a jig for setting the blade angles and...a tube cutting guide? The yellow gizmo in the center of the parts collection photo looks like one...

The blades are glued to the fiber hinge at a 90 degree angle. You set the blade pitch or what ever you wish to call it with a set of three jigs.
Attached is an image of the blade jigs in use and a close up of the hub. Quote:

Thank you for coming out with this FAI-type heli-roc kit, John! This configuration is also popular in Europe (and in FAI-CIAM spacemodeling competition countries elsewhere in the world), and it might even become the "Renger Sky Slash of the heli-roc field," in its total impulse category.

Do you really prep for flight by routing the rubber bands inside the hinge? That's a pinch point. I'd keep the bands out of the hinge mechanism. Putting the bands inside the hinge "ears" could lead to a no-deploy. I'd route the bands around the outside of the hinge "ears," not like what is shown in the diagram.
