Jupiter Kwirl easy to build autogyro with counterrotating rotors

Remembering the fun I had several years ago with Al Foot`s wonderful Twirl, I made this simple Depron Autogyro. Counterrotating Rotors, RET controls. Fuselage is taken from my Jupiter Junior biplane design. Plans are in preparation and will be available as a free download on Modell-Aviator.de.
First flights were not succesful, it was willing to go in a turn, but refused to go back to neutral. Rotor dihedral solved the problem and now it is a great fun machine.
Working title is Kwirl in honour of Alīs design.

Hi Thomas!

Your autogyro is really interesting!
How is the rotor constructed? Angles of the blades, materials, bearings, etc. ..?
Is it possible to buy the plan?

Hi Tomas,
I am working on the plan. It will be a free download on Modell-Aviator.de. I will post more information here, too. The rotors are 3mm Depron reinforced with skewers. Bearing is plastic tube from glass cleaner running on a 3mm CFK axle.
I had a lot of fun with it again today.
Best Wishes
Thomas

I think most of us moddelers dont have the attention-span to wait that long!

You will have to give us something before then!
