I just tested several 500 mph pull outs starting from 3000m after bomb release with full fuel from around 70 to 80 degree dives with no breakup, certainly it stressed the aircraft a few times but this all depends on how hard you pull out (lol), what would you expect from a several ton aircraft. If you pull out of a steep dive with 500 pounds of bombs on each wing bad things are gonna happen, but I didn't notice a problem with no bombs. Still keeps energy very well, and zooms back up like it should. In short I didn't see a problem, it still out dives nearly everything.



What angle and speed are you diving at, with bombs? and how much fuel? and what speed is your pullout?

Bombs and fuel are now critical factors to what you can do during a dive bombing run. I've run a few dive bombing runs in the FW190, P-47 and Tempest which are all bomb carrying aircraft with historically above average strength airframes. I haven't broken any of them yet...except when I went nuts and I did a hard pull out in which case all of them exceeded the airframe limits as specified in the game and the aircraft broke.

I think this patch has been harder for people who in the past have treated the aircraft as unbreakable and stressed them to the limits at all opportunities. Although I flew like this in the first couple of years of playing the game I later learned that the better way to fly was smoothly and calmly with deliberate and planned out action. The benefit pre-4.10 was a aircraft that flew better and faster. Now those benefits are realized in not breaking the airframe as well.

When flying IRL manouvre speed (Va) is one of the most important things to know for an aircraft, especially when flying aerobatics which I have done quite a lot. It's nice that we now have it in this game too. I'm pretty sure that the P-47 was famous for high speed dives as it did not get control surface flutter and compression problems, and not due to the fact that you could pull the stick in your belly at near mach speed?

Because the way the G loading is model it hasn't taken in account for aircraft like the P47.
Blackout is not instant, in planes with relatively light controls and at high speeds you can pull lot of G's without blacking out but that amount of load is something that wings might not support.

P-47 is strong plane but that is related to its ability to sustain battle damage. In terms of overload resistance it is in similar category as most of the other fighter planes.

I think 190 and P-47 are close to its g limits, but there is some major discrepances. Spitfires and Zero taking more than 9 Gs and Hellcats taking less than 7 to overstress at default configs.

i'm still playing with stuff to figure out the new FM's, but I can safely say the new "stress limits" are a tremendous improvement.

These planes were not tanks. They had to be caressed, not beaten. Some withstood G forces better than others, but all of them could be torn apart.

I remember an interview with a 109 pilot who said it was possible to turn the plane hard enough to rip the wings off. What we saw previous to 4.10 was a sample of what such planes COULD do if they were indestructible. Now, we are seeing something close to what they could do realistically.

And if all that is too much to deal with, you can switch it off in the difficulty section.

Default For those interested, here is a real P-47 pilot talking about Compressibility

Okay, so the P-47 was renowned as being a real tough bird. I posted this on the ubi forums in 2008 and if you give it the chance and download the audio file, you will here Art Fiedler of the 325th, who flew P-47's and P-51's (He was an Ace in the 51) talking about the problems that pilots encountered in the P-47 and also the fact that he never once saw a wing break of a P-51 except when an undercarriage malfunctioned.

Here is that post;

In August I travelled to the US to visit and interview Art Fiedler of the 325th Fighter Group/ 317th Fighter Squadron, and to watch the Camarillo Airshow which he helps organise.

On the final evening I was invited along to a Barbecue at Art's house, where along with Monguse, we took the chance to set up a video camera and record Art talking about some of his time in the USAAF.

After the video interview, I asked if it was okay to leave the sound recorder running while he chatted with guests at the meal, and with a beaming smile Art said "Sure!".

You'll be glad to know that I have edited away the dead space (walking around, nothing being said, etc,etc) and left in just the conversation related to his time in the USAAF.

Covered in this audio file are P-47 gunnery training, P-51 wing snapping (or lack of it), engine noise, flames on exhausts, weapon and tracer load-out, the use of long range fuel tanks as weapons, plus many other topics.

Asking most of the questions is myself, but the other voices you will here are 325th_Swoop and Monguse (he comes in right at the end asking about P-51 markings).

Guys, the audio you will hear was all recorded at a Barbecue, so there is background noise going on, but Art was fully mic'd up so when he and I talk, all the voices are very clear and the background chatter is just ambient.

The file is just under 30-minutes long, and is compressed in mp3 format, and is 26mb in file-size.

I hope you enjoy listening to Art talk about some of his incidents as much as those gathered there did, he truly is a remarkable man and it was a real honour to spend time talking with him.

The audio starts as 325th_Swoop has just told me he is 62-years old and is learning to fly a Helicopter. Art then comes over and the conversation gets going.

BTW Swoop doesn't look a day under 62 Wink (kidding..he must have had an easy life!)

Would like to hear what you think, cheers, MP.
