Managed to recover crate in 866m, second best 882m. 100% fuel, default armament, track version .TRK v4.08.
I think some of those stuff posted by you guys really works, and TBH it can be done even in a less altitude. At least I have this "feeling" . Anyhow can't be arsed for further recovering .

BTW awesome upload site, one must admit that . Nice 'n easy.

The P39 is a favourite of mine also. Apart from the Spitfire, I like flying planes that people consider cr@p or too hard to fly (like early planes), simply because everyone will rush for the `uber` planes like lemmings. Guess it`s my `be different` stubborn streak.

Anyway, the P39n1 is a great plane and most stalls can be kept to a minimum in combat or recovered. However, I simply don`t waste time trying to recover a flat spin once I get to 1000 metres cos after that chances are you won`t make it.

Cobra stalls aren't all that nasty as they might seem... flat stalls are quite rare, at least in my experience. Most of those can be avoided...

TA-152 seems to be also one of the planes with nasty (flat) stall chars... also can be de-stalled flat for fun .

However... flat spin + combat damage is probably an one way ticket especially if they happen at low alt .

Interesting, no aileron and engine at idle (flaps and gear down as before) does seem to be the way to go.
Tested it a few times - it does produce consistent recoveries in about 800m.

Hi.

It seems that applying full aileron in the direction of the spin speeds-up the recovery.

In a spin from 3000', recovery is possible in 2,500' (762m) by immediately:

Close throttle
Full flaps
Full opposite rudder
Full stick forward
Full stick in direction of spin.

Without the latter, one runs out of space and it's goodnight Vienna...

Don't know if air density plays a part?
From 10,000', recovery as above took 4,100' (to the point where I was no longer losing altitude).

From 6,000' the recovery took 3,600', and from 3,000' it took 2,500'.

Crimea map, full everything. P39 D1, 1941.

Argh, I just had to



Spin recovery using 50% fuel and aileron.

Seems like recovery don't pick up until I push full elevator forward and aileron input slows me down initially, which would indicate less effective recovery. Will do one without aileron later

P39 is a sweet ride (one of my overall fav <3) that engine in the middle reminds me of high end sports cars. It has an awsome gunsight for those high angle shots. It's kind of an Bf-109 with reduced maneuverability but more stable and less "jerky".

But it will kill you every now and then


My rule of thumb- if you are not higher than 1500m just hit the silk.

The P39 absolutley rocks. Great advise in these posts for flat spin recovery, thanks guys. I love the P39 even more now

Ive never really had a problem with the P-39. I dont try to pull abrupt movement with many planes (exept the P-51 If moving at +250mph) Ive never been in a flat spin either but I think the best way to get out of it is to apply full opposit rudder, and point the nose down with 0% power.

Interesting to see some science added to this post after everyone has tried it for real.
Can't wait for your print out without aileron "MatZ" to see if what we found out so far is verified.
As for applying aileron "into the spin"?! Well, all I can think is that the drag of the "down going aileron" on the unstalled wing is providing some drag to slow the rotation down.
I'm not convinced that it will help though! Certainly not IRL.
IMHO the movement of the centre of pressure aft with the use of flap is what is lowereing the nose enough for the rudder to have airflow and thus stop the spin.
Fascinating anyway.

P-39: It was put into production before all the bugs were worked
out. And, yes, it certainly should have retained the turbo-supercharger it
was originally equipped with (which gave it a top speed of 390 mph at
20,000 ft when it was first flown in 1939, making it much faster than any
European fighter of that era). The P-63 was the aircraft the P-39 should
have been. The early versions of the P-39 were underpowered. The Q
version was actually quite good, performance-wise, but still suffered from
over-sensitive controls and the rearward movement of the center of gravity
once the nose ammo was expended. This made the plane susceptible to flat
spins. Experienced pilots could handle it. But most service pilots first
got their hands on a P-39 with less than 300 hours in their logbooks.
It was an easy plane to bail out of: merely jetison the door and roll
out. It was actually easier to bail out of that most other fighters.
That's not really saying very much. The chances of a successful bailout
averaged between one in four and one in two, regardless of aircraft type.
The chances of successful bailout varied based on the reason you had to
bail out, the attitude of the aircraft and its motion, and what the
altitude was. P-39s were notorious for killing their pilots because they
used an unreliable electric propeller that often ran wild. At altitude, no
problem. The pilot merely exited and floated to safety. But if it
happened at low altitude--and it seemed to happen most often when pilots
were practicing touch-and-goes in the landing pattern--the pilot usually
died. This was because the pilot tried to do something to bring the prop
under control, all the while losing altitude and airspeed. He often stayed
with the plane until it stalled and then it was too late. Veteran P-39
pilots got the hell out at the first sign of a runaway prop.

"Overall i think this little plane needs to be flown with great finesse without too many jerky movements, I am getting quite use to this trike, as i racked up 3 kills on it the othernight with some low level dogfighting. Managed to keep it fast and basically B-n-Z my targets and stroked her ever soo gently.."Whoa offtopic!, but i made it back to base "

"Interestingly, I thought for a moment that you had discovered a very unusual spin recovery trait for this machine by using

"aileron" in the recovery (I see the stalled wing with down aileron....more drag!!) This is a no-no in all the types I have tried

IRL, but I thought maybe it had helped?"

"I'm not convinced that it will help though! Certainly not IRL."



Taken from Pilots flight operating instructions for the P-39Q-1 Airplane:

14. Spins.
Deliberate spinning is not recommended. However, if a spin occurs, rapid recovery can be made as follows:
a. PRERECOVERY.
1) Throttle must be off.

2) Propellor must be in low rpm position.

3) Stick full back.

b. RECOVERY.
1) Apply full opposite rudder when spin is at its slowest.

2) Wait until rudder effect is noticeable, then apply full forward stick and ailerons against the spin regardless of ammunition

load in the wings.

c. The spin is usually oscillatory in rate, and it is mandatory that the opposite rudder be applied when the spin is at its

slowest.

d. If the procedure above is followed, the airplane will recover in one-half turn. If the proceedure is not followed closely, the

airplane may not recover.



The game P39 spin recovery isn't at all accurate compared to RL, but certainly in RL opposite aileron as an aid to spin recovery wasn't unknown.


Also, from Republic P-47 operating instructions:

1) Full opposite rudder.

2) Neutral elevators.

3) Ailerons full against spin.



As to whether it helps in the game or not, just try entering a flat spin from straight and level at 3000' over the crimea sea, and compare a recovery with aileron into the spin to one without. That's the simplest (and wettest) way...

Having said that, the flaps are definitely the key. They make it all possible...

That's so interesting OMK and thanks for finding that.
I had a feeling that they must have explored all the "avenues" to try and guide the poor chaps to get out of this situation. I never knew that ailerons were used in so many types to get out of spins. I still do not understand the science behind it though!

Just one more thing......

How many of you guys "explore the envelope" in the types that you fly online before you drag them into combat?
I get the impression from some of the posts that some "hope they will never get into a spin"?
I have to say that it is what I find so interesting about flying a new type, and in any case I try and chose tropical waters for a warm swim on the first few attempts.
