It's cool that they've got this far and kudos for that.

I say the teaser videos are mostly useless though in actually selling a product like this. Might generate general interest but few would follow through and buy based on this video. Add some facts as this is clearly already flying- weight, cost, BSFC, TBO, availability wouldn't be too much to ask... That would generate more genuine buyer interest and less questions.

Can you shed more light on this? From what I can ascertain the problem is spin recovery (or the lack of). From one article:

Perhaps this should be it's own thread ...
My friend, in his capacity as an instructor, was converting the new owners onto the type and each of the syndicate's members,bar one,turned up to be trained. In turn, each convertee went up with the instructor and carried out a local flight and demonstrated manouvers such as turns, practise forced landings and so on and also slow flight to the pre-stall buffet. By the late afternoon, it was time to wrap up and put the aircraft away when the last member turned up and asked to get in a flight.My friend obliged and off they went. The rest of the group went home. When the instructor didnt arrive home for dinner, his wife began to ring around to see if he had gone elsewhere. The airfield owner found that the aircraft had not returned before nightfall and began to alert the relevant authorities about a missing aircraft. In time, a SAR heli was tasked to check the local area with night vision equipment but failed to find them but they were found at dawn the next day, in the corner of a field. The aircraft was mostly intact and unfortunately,both men were dead. The aircraft had clearly fallen in a flat attitude and virtually all of it was in one small area. The GPS and other electronics had survived and were able to give details of the flight route and behaviour. It is still under investigation but I know that it is paying close attention to the C of G position.

Wonder what I could do with one on my CGS Hawk? VTOL? I imagine the climb rate would be good, until fuel ran out. Fuel consumption figures would be interesting to see. Pops, wanna do a SSSC with a turbine?

Youd be out of gas by the time you taxied to the end of the runway with only 5 gallons...

That video is horrible... I was waiting for it to say...Next time on Survivor!

I hate it for the loss of your friend.. My heart goes out to you.

I read about concerns with spin recovery ability (or the lack of) in a few stories found on the web. Until now I wasn't aware that this may be an issue with the design. I really appreciate you taking the time to pass this along.

TWO of these turboshaft-engines on a Lockwood AirCam would be awesome and would win all the SuperSTOL competitions....
The free publicity would be massive, if handled right!

So, about 70 PPH fuel consumption. that puts a limit on your flight time on a lightweight aircraft unless you have lots of excess payload capacity.

I like it, but you have to go in knowing the trade offs you’ll have to make.
I wonder what the TBO overhaul costs are?

Fuel consumption: 32kg/hr Diesel
= 10.8 GPH
Since I doubt there will be any earth shattering improvements in efficiency over what we already have, let's average the numbers and we end up with: ~.6 lbs/eshp/hr. or;
.6 x 120 (realistic eshp) = 72 pph / 6.7 (fuel density) or 10.7 gph.

Isn’t that what the last line in the specifications means? €13,000?

I see that the original poster peruses this thread regularly so why don’t you tell us how much is things gonna cost?

be aware then anything over about 20,000 bucks US it’s going to be declared a nonstarter here.

All I know is it would look great on the front of my current airplane ...

I think two of them would look wonderful on my amphibian at $20,000 apiece I think they would be plum ugly at$100,000 apiece
