.. I want to build.
Ain't it a beauty?

Bad luck it's badly behind schedule. And German UL approval of the design has not yet even started.

Yep, sure looks good! But like just about every good looking enclosed machine there appears to be a problem with insufficient tail area. I suspect that if Doug Riley did an analysis of this design like he did with Ken Rehler's that it would turn out very scary.

It is clearly derived from Tervamaky JT-5 that by the way the production rights belongs to Magni!

I guess, all single place pusher gyros with decent aerodynamics will look more or less like a JT-5.

Tervamaki's construction dates back more than 30 years and its speciality was that is was almost completely built out of fibreglass.

The DF01, from which the DF02 derives, was built by François Dedieu who flew it for several years. I cannot remember, Magni ever complained the DF01 was a Magni clone.

First of all Magni couldn't complain for DF01 because you can buy the plans from Tervamaki and build one gryo for yourself (Magni has rights for industrial production only)

You are right but look its aerodinamics and shape, air inlet is identical to JT5, the position and shape of fuel tank (which in JT5 and DF02 is very particular with the rods that passes inside..), ....... I could go on

anyway I'm not connected to magni and I really don't mind, I just noticed that is similar.
Anyway I must admit that airframe is original and different

Hello Greeny.

Lovely looking gyro.
Magni also came up with a similiar looking kevlar machine, with the larger rudder/HS.

Hope to see you flying soon.
Good luck with the UL approvel.

Best wishes

Hello guys,
I am the producer of this little machine. I'm happy you like the design.
Dean Dolph: I know the problem of stability of enclosed machines. The prototype DF01 is absolutely stable, even at 180 km/h. That's one of the reasons why I bought it (the exclusive right of serial production included). See details on our site, I am not telling lies.

How to stay away:
stair step profile for the frame?
Bullet shape for the cabin?
thanks

Michael, the question is, how is it with the engine stopped and having to land with 30 km/h cross wind? That is the real test. Great looking machine though. Congratulations.

Simple Paul you turn ito the wind you know that..... The one thing that grabbed my attention on the website was the fact he quotes a 300 rpm prerotator, now in a light machine that could get very interesting, but yeah nice looking machine

Heron: Sorry, don't understand your question - -
Aussi Paul: Is your question: "Does the machine turn the nose out of the wind in crossfield landungs without engine", then the answer is no. The prototype turned the nose into the wind like other machines, too. As usual, you should be careful with stronger crosswind landings without engine.
Bones: The 300 rpm are projected - I try to achieve that with the serial machines, the prototype had a different system. But it should be possible with a 24 ft. rotor and driven by cardanic shaft.
