"You can hear him cut the power after the first spin to try and stop the gyration."

You can also hear a bang coming from the engine. It is possible that the other engine had a slight malfunction when he went inverted so he nearly immediately cut power to counter the destabilizing effect.

"Sounds logical, I don't believe a mossie would have flat stalled that easily."

If you look at the fuselage profile of a Mossie and the size of its vertical stabilizer I do not wonder at all that it behaves like that if the power is lost from one engine in a difficult flight state. I also remember reading that normally one engine flight was not a problem for Mossie.

for sure, one engine flight is not a problem maybe if you are expecting it, but you lose an engine in any type of vertical turn it is bad news. talking purely of our virtual mossy that is.

The Barten crash report has been posted in the past before.  Here it is for reference:

http://www.aaib.dft.gov.uk/cms_resources/dft_avsafety_pdf_501355.pdf

The conclusion was that the left engine unexplicably lost power somewhere near the apex of the wingover.  No conclusive proof of the loss of power was determined but the circumstantial evidence suggests that the left carburetor was partly the culprit.

The report theorizes the "bang" heard was related to the rapid reduction of power by the pilot to arrest the left yaw due to assymtric prop effects at the apex of the wing-over.  At any rate the left engine lost power going into the apex prior to the "bang".

The video is an example of what happens if you put a plane in a low airspeed situation in an odd orientation.  This leads easily to a deeply stalled aircraft because the aircraft easily and very quickly transitions from aoa for normal flight to well beyond critical aoa in a blink of an eye (in this case aoa to 90 degrees relative to the wing in about a second after the peak of the apex).  The point is that anytime you're in a low airspeed situation like this in the vertical you can end up deeply stalled --- power failure not withstanding.

Anytime I see a crash like this I'm horrified by it and always get a lump in my throat knowing that lives were lost.

  :salute to the pilot and Mossi.  Sad to lose them both.   :frown:

I think the handling characteristics are modelded correctly from what I have read (and seen), but the FB Mk VI we have in the game is still 5-15mph too slow depending on the alt.  Multiple thread have pointed out the errors with legit proof.  Lets hope HTC eventually takes the 15 minutes to read, verify, and change the Mossi to the correct speeds.   ;)

Also the elevator feels anemic. It is as if we are flying with the stall limiter on, or as if the elevator is connected to the stick with rubber bands.
