Dihedral should be around 6 for each blade. That is 2cm at the tips.

Hi,
Thanks for the pattern PDF's.
I thought the original printed was small.
Same for these PDF yet larger.
Yet, still a tad small and runout.
Only can get 96 of 100mm scale and some runs out past page with A4 in landscape.
Think I will get some legal paper and increase % to about 103.14% n should work.
Or, am I missen somthang ?

I wrote to the editor. I hope they can solve the problem.

I have designed a rotor head than can be laser cut from plywood (either 1.5mm or 0.8mm - will need to test strength). It will give the correct pitch and dihedral and the blades will be removable. Either ball bearings or a simple bearing tube can be used with the head. Unfortunately my laser is over 1000 miles away from where I am at the moment. I won't be able to cut and test the design until Christmas.

Not a problem at all Thomas, just a challenge and asking as I am not the computer dweeb of me yesteryear's.

I re - checked the sizes on my printer:
Lockey`s patterns are exactly right, the download plan is almost 20% too small. They also got the rotor diametre and length data wrong: right is 52,5cm diametre and 56cm length.
So I recommend using Lockey`s patterns for cutting and the plan for general overview.

Michael, I can`t wait to get some of these rotor heads!

Lets see if they work as intended first Just because they look OK on paper doesn't always mean they work in "real life". Basically you just glue plywood root pieces onto the blades and these then slot into the hub and are retained by a small screw. I'll post up the drawing of the parts when I've done the final touches.

Download plan now correct


Modell-Aviator corrected the size instantly, now you can use it without calculating. Here is the link again:

Excellent and thank you.
I printed out with A4 in landscape and am even closer enough on standard letter paper.

@Thomas B : you're lucky! All trees around here are damned plane magnets. How did
you turn it off for the video ?
I would not dare to fly in such cramped environment : thumbup:

You just have to build a Kwirl. It has an automatic tree-avoiding- system.

The problem is the magnetism of orange and green Kwirls:

If I ever built one, I'll take you up on that!
Suggest to choose other colors to avoid green-to-orange-magnetism.

Are they ever really "done"?

Fantastic! I have been quietly following Lockeys' adventures in autogyroing (is that a word?). For a few weeks now. Stumbled on the jupiter...which led me here. I just really wanted to say thank you so much guys for sharing this. Simple, afforable, easy to build. How does it get any better? Great work guys!
