Hatz Biplane Association

Dear Hatz friends,

We are pleased to let you know, that we now can fly anywere we like! What a thrill!
This weekend we attendet the 50 years Sitterdorf Fly-In and had much pleasure! Everything went well.
We even got allowance to make a "low fly pass" (at 300 feet he,he,he - that high for you US Hatzers, isn't it?) just like the professional demo fliers do. That was stunning!

Now we have about 42 hours flight time and the plane and the Rotec just perform excellent. Cruise a 2000 RPM is about 90mph. We shurely don't have the fastest Hatz, but it's great fun!!! Here a few pictures of our "Vintage Hatz" at the Fly-In.

Best regards

She's absolutely beautiful, Hans and Sam! I bet she was the hit of the party! Maybe we will be selling Hatz plans to your part of the world now. Good show, sure wish we could see her here!

Glad to hear that you have flown off the required time and she is performing well. I love the show pictures, you both must be so proud of such a great achievement.
I am also building a classic with a Rotec Radial and am interested in the prop that you settled on and are you happy with it.

Dear Ed,
Our Rotec is performing very well on a MT wooden prop with dia 2050mm and 1200mm pitch. We might choose may be rather 1250mm pitch in order to get some more cruising speed. However, you would loose a bit in climb performance. We have about 90mph cruise at 2000rpm, which is good for us.
Kind regards
