They spent 7 years building it and it's powered by 2 Moki 250 5 cylinder radial engines. Sounds fantastic, landing a little nervous but I think anyone would be.

I got the impression that almost the entire flight from the beginning of take-off, the flight, to the end of landing was on the edge of disaster.

Quite agree didn't look too stable, didn't see the rudder move so no coordinated turns. Looked a little tail heavy & with too much control movement which makes it twitchy. Cracking project though.

Agreed with the two comments above.

The pilot lacks skill and it’s a wonder it’s not a kit again!

Take off was ste, what on earth was he doing with the rudder and the landing even worse. Not sure if the cheers and clapping were simply because it was still in one piece smile

Nice model, clearly flown by someone with more money and time than talent.

I'm impressed.

What country are they based in? They are obviously a bit circumspect about showing a full swastika on the tail.

Sometimes I watch a video and read the PH thread comments and wonder if some folks have watched the same video.

Pilot was a bit nervous, who wouldn't be? But on edge of disaster throughout? Come on, really!

Nice model, nice sound, seemed to do things reasonably for a first flight and first landing. Nervous landing, fair enough imo.

Still we can't all be driving gods.

With the stylised Swastika and the owner being one Franz Obenauf, Germany seems a good guess smile........but Googling shows Austria as his place of work apparently. I guess they are also a bit wary of flaunting the Hakenkreuz.

Watching the video again, the buildings show the logo of HB, an Austrian light aircraft manufacturer.

Maybe a few words for the first flight.
The rudder throw were partly 80% too big.
After a short time, one receiver has failed, bad antenna installation.
when Gear pull in, 11 Kg move backwards.
it is a self-construction, we only calculated the center of gravity.

My understadning is it's illegal to display the Swastika, even in context; there have been fines handed out in europe.

First flights are always a nervous affair, but with the radio being used there, (Jeti DC-24), he could have made life a lot easier with a bit of thought and programming. He needed to set up flight conditions and also could have set variable rates to mitigate either too much or lack of control movement.

For me, the aircraft looked way to sensitive and because of this was being over controlled.

Bloody nice model though!

And no-one noticed the aircraft ID on the side of the fuselage?

What has this place turned into....

Test flight took place at Flugplatz HB Hofkirchen (Hofkirchen Airport), about 200 km west of Vienna, and a little north from Steyr in Upper Austria.

Very nice. The trailer looked a project in it's own right as well.

Having flown a few RC planes in my time, most of which I built, I'm a bit more sympathetic to the pilot on this one. That's a very big model with different inertias to the majority, so it's going to handle differently and it's going to take the pilot some time to get the feel for it.
The control rates did look a bit quick but having experienced a few first flights myself it was probably a case of "it works, lets not mess about with it until it's down and we can have a calm think about it". That's been my thought process on a few occasions.
Some of what may be considered erratic flying could just have been the pilot getting a feel for the controls.
