How about trying this...or at least checking my logic ;)

Any try to feather the prop?

Only reason I say this is because when the engine is off, like when the mk1's are fuel starved the prop is in effect driving the engine?  So feathering the prop might let you get enough forward momentum to get the craft righted?  Just a thought, kind of odd, but it's like getting your max glide from a engine dead plane by feathering your prop and hitting alt x.  It sounds wrong but head to the TA and try it, it works like a charm when nursing a wounded bird back to base.


Just a thought anyway ;)

Tried that, which is conventional spin recovery.  No dice.

Tried raising flaps.

Tried lowering flaps.

Tried full power.

Tried no power.

I do not like it, Sam I Am.

It's the flight model. 110 does the same thing: if you run out of speed at the top of the loop => inverted flat spin. Somehow they forgot that stall inverted is allmost the same thing as stalling upright. Otherwise you would end up flat spinning to the ground in every stall you make.

One other mystical thing about AH FM is the never ending tailslide (202 and 205 are notorious with this), which is also impossible to perform in a real prop AC.

I did get into one once with a Hurrin MKI Schatzer. I rode that puppy all the way down from 20K+. Fighting it,  cussing it, bribing it, and begging it  to stop.
Never thought of dropping the gear.:huh

Anything that'll let you fall that far doesn't qualify as a lady.;)

:lol :lol





Seriuosly, though, I have a question. Somebody said that a flat spin and an inverted flat spin should behave exactly the same...but that doesnt make sense to me (a non- engineer0. How could they be exactly the same when the lift vectors are oriented in opposite direction? I know lilft is lost when the spin happens, but as recovery is attempted lift should be partially restored....

They're not the same and they don't act the same.  There are very different aerodynamics between upright and inverted including the effect of the fuselage, vertical tail, rudder, airflow over external stores or landing gear.  

The description Jenks provides is more of a departure than a spin in that he's not in controlled flight yet he has no yaw...hence no spin.  It actually sounds like a problem the F/A-18 had where it would hang up in pitch.  You couldn't get the nose up or down and the rudders were blocked by the fuselage so you couldn't rudder out of it but I've never heard of a WWII demonstrating it, especially inverted where your vertical tail and rudder are exposed.  Sounds like a software issue.  Strangely enough the F/A-18 issue was corrected with software.

So this would be called the "Rhythm Method"?  I hear it's not that reliable. :D

I can get the dreaded Flat spin stall in a spit 5 when i'm pushing it on the edge ... its pritty rare accurance but it does happen  
normally if you have enough alt, you dont notice it when it happens as much .
watch your air speed and you'll see what i mean when you've pushed the spit past the edge .

in the spit 1 i can see it happening when the eng is in neg g stall  .
