Sorry.. for me he actually says.. 'Nothing' But before you 'take off'... This type of 'analysis' is normal in the 'Real Life' of aviation. No one is prepared to make an 'absolute statement' for fear of prosecution.... probably due to the USA lawyer association :-) Joke intended...

That's a pity.. a IL2 had a lot going for it.. Turning one's nose up at an excellent product (be it yesteryear) you'll repeat the same mistakes.... and may I say 'this is already happening'

The AI is nothing more than 2 basic tests. 1) if it has height advantage.. it farts around doing spastic rolls... a quick easy kill. 2) if you have height advantage.. suddenly it wakes up and starts flying but as you fly continuously between 1) and 2)... it's a no brainer. I prefer to practise, letting the FW get behind me and then I start to have fun, seeing how close I can tempt it... but then we're dealing with the AI programmer... so even this gets boring!!

Nope... I think this, or a comparison thread, is as good as any. DCS has a flight model, improved on IL2 no doubt, but a lot can be learn't from the IL2 series wrt to prop aircraft. :-)

Just renamed and uploaded... I don't think it's a copyright issue as this doc is widespread.. maybe it's a time limit on dropbox ??

OK.. hang on a bit

This pdf is available elsewhere in this site... but have a good read :-) https://www.dropbox.com/s/0ynq0wumxwzb2rg/P-51D-K%20Manual.pdf

The dorsal fin AFAIK was introduced for 'high speed' directional stability, same with the P47 and B17.. In any event a snap roll, if down properly, is mainly around the Z-Axis, with a little yaw in the process. It might reduce the yawing effect, but it certainly won't prevent a wing stall, if you force the aircraft into this situation. :-)

Sorry .. yes you're right https://en.wikipedia.org/wiki/2011_Reno_Air_Races_crash In that link is an interesting one on Bob Hannah on the forces on losing a trim tab ??? Heavy stuff !!

This, if I remember correctly, sadly was the cause of the death of Jimmy Leeward, in Galloping Ghost, at Reno a few years back.

Here's the track.. 2x attempts to snap to the right under power... 1x attempt after cutting the power... eventually draaagggs itself over. It's not much better rolling left, although it does get there in a similar manner as the right roll without power. I actually think the engine moment/torque/propwash-vs-control surface effects ratio is not right. snappy.trk

I'll do another test tomorrow and post the track - must set up my rig again. :-)

You have an interesting point.... 'implementation of snap rolls'. From my POV, I've tried to 'snap it' (in the pure sense) either left or right, with power or without power on the Poti free flight map. The result was.. for an aircraft very sensitive to G stalling, was that it got stuck there.. hanna... hann.ering between max rudder and elevator application actions when rudder and elevator were applied simultaneously (=simultaneous a/c reaction) , wobbling back and forth. After 2 or 3 seconds... 'Ah yes !!!.. I'm going to now do this' ??? It's a bit late for that ...said Jimmy Carr :-) It has nothing to do with propwash or engine torque as I had the same reaction with full and idle power. As far as I'm concerned this IS a modelling flaw and hope it will be resolved for both the FW and the P51 as it is a significant part of one's flying repertoire.. :-)

I suppose it would depend on stress factors (speed)... so I'd imagine this would only be executed at lower speeds, otherwise I'm sure the wings would fall off :-)

It's a very fast 'circular' motion wrt to stick and rudder. You simultaneously pull stick and kick rudder hard. This essentially stalls the aircraft, slowing it down and rolling it in the direction of rudder application. You can hold it there for a while if you like, but be careful not to go into a flat spin.. But usually after the first application you 'unstall' the aircraft in a classic stall recovery = Stick forward and opposite rudder. The 'unstall' is done as fast as the induced stall (circular stick and rudder motion).. and you're good to go in whatever direction you've chosen to recover in. Make sure you're looking ahead when you do this.. for orientation stabilisation. :-)

There is a P51 doccy (on my DVD's here somewhere) where the pilot explicity mentions how he executed the snap rolls to escape Me109s.. (no aerolons applied :-) )as plain as daylight.

Yessir.. I know that, did it in my training, but when I mentioned this P51 modelling flaw, I was 'shot down in flames'.

Finally, on this forum somebody agrees with me... thank you DavidRed :)

.. is the word. Nothing like simultaneously pulling hard on the elevator and kicking hard rudder (no aerolons) for a quick snap ? :)

Maybe the FW190A8 manual might be usefull.. https://www.dropbox.com/s/wseicvcwi7j4fuv/fw190a8.pdf

The problem with the upgrades, is that it still overwrites your profiles that you've spent hours testing and tweaking, There's a little note saying you must 'make a duplicate file and keep it in your user folder - the game references this'. Sure I've yet to see this work. Such a simple feature to fix yet so annoying. The way around this is, once you have all your profiles sorted, back up the files somewhere else on your PC and after every upgrade, copy them back in. In addition you can also export your profile in the options menu - find this file and do the same as above. :)

Vlerkies and TT.. Got my forums mixed up, but you probably seen this already by now https://www.dropbox.com/s/4le9ssjw2jc2nqs/P51TakeOffLanding.mp4 :)
