Select a photo and click on it to see the larger,  easier to view photo

To view the actual plan/drawing of the small 3 blade "Simple-Delta" rotor hub plan, click here

If you want to print this plan,  it should print out full size at:  635 x 825.

The left photo compares the new minnie size (3 foot rotor) design of a simpler delta angled polyproplene hinged rotor blade hub... (shown on the left in natural wood color) ...   and the standard non-delta Minnie hub, shown in black.   Click on the photo and look closely and you can see the blade holding tangs slanted forwarded at a 15 °  angle.

The photo on the right compares the Minnie sized  (3 foot rotor or smaller)  "Wayman Delta"  hub design with the larger  (4 foot rotor size) Wayman hub....

An even smaller delta (sub-simple D) hub has been constructed and tested on the "Whirl" (.10 size model)..
