Engine problem or not it is notable how easily the plane starts to slide sideways nearly entering a flat spin.
The Mossie does not have too much side surface to counter slip and the smallness of rudder does not help either.
It is also notable that despite those factors the pilot is able to get it under control. Slightly more alt and he probably would have made it.
Those were my thoughts as well.
While an engine trouble might effect a plane into entering a flat spin more easily than under normal conditions, especially during such a dangerous phase of flight as being at the apex of a loop, watching the mossie literally "slide sideways into an uncontrollable state so easily", as Charge puts it, seems to suggest the "weird" stalls in 110s or Mossies may not be so 'weird' after all.
If an engine problem occured during the climb, the loss of power makes it impossible for the pilot to complete the loop, and therefore, puts the plane into a state of tail-sliding downwards. As a matter of fact such things happen quite frequently in some planes in AH2, an example being the Ki-84 and the Ta152.
((
Note: Although many of the better pilots claim such things do not happen with these planes, they seem to forget just how easily us more mediocre pilots can push our planes into troublesome situations. The odds are, the veteran pilots don't notice problems because they avoid going into such situations in the first place, whereas we medicre guys, do quite often push the plane in the 'wrong manner', and therefore, demonstrate that in such circumstances indeed, the described dangerous flat spin does happen.
Countless times, out of desparation. I've pushed Ki84s or Ta152 into a vertical, at which apex, I quite frequently lose control as normal airflow is lost, and the plane enters a tail-slide, which quickly evolves into a flat spin that is very difficult to pull out from.))
Quoting the words of bozon, "once normal airflow is lost, anything can happen". If, a big IF, the above recorded incident was not an isolated one, but rather a rare footage of the tendency for planes with similar profiles as Mosquitos to fall into similar spins under extremely dangerous conditions, then it somehow makes sense.
Come to think of it, the Ta152, P-38, Mosquito, and 110s, Spitfires and Ki84s - the planes in AH2 known to enter dangerous flat spins during harsh maneuvering - all have a similar profile IMO.
* The wing area is relatively large for the size of the fuselage
* The fuselage is often very slim or slender, when compared to the overal size or length of the wings
(elongated fuselage in the case of the Ta152, very slim and slender in the case of the 110, Mossy, and the P-38. The Ki-84 or Spitfires also have small fuselages compared to the size of the wings).
* The area of the side surface is also very small when compared to most other planes, like Charge has observed.
* The overall ratio of the plane's breadth (from wingtip to wingtip), to the length(from nose to tail), is also much larger than other planes.
If there is something indeed wrong with how AH2 FM handles planes of these profile types,
perhaps it is not completely wrong, but rather exaggerates an already natural tendency these sort of planes might actually do have in real life. My 2 cents.
