Digital Ms Sidewinder Prec.pro; No wingtip rip-offs. Maybe it's because no spikes here

Flying almost solely the 1D and very rarely do I pop the wings.  MOST the time it is head up prettythang syndrome and pull too hard too fast at too high of speed.  BUT I have had the time the mech seemed to leave out some wing rivits or my folding wings didn't lock down all the way and in the gentlest of pulls the wings seemed to seperate with a nice loud bang.  I use a MS 3d PRO stick.  This is a rare event for me but it is one that happens from time to time.

S!

Well, I can say it is stick dependant. I use a MS Sidewinder 3D pro, and have ripped wings once. Aside from the A5 incident above, that's all the airframe abuse I've gone through. I blew the wings off a -D Hog this morning my simply pulling up easily to get out of a 400mph dive. No spikes, no jerks, just a long smooth increase in back stick pressure. Only pulling 1.5 Gs, and WHAM! Suddenly the Hog I'm driving has a 12-foot wingspan.

Did the same thing in a Mudstain. Dive to 400mph and pull out real easy. BANG! No wings. Definitely a rivet problem here. I tried it in a P-47D just for kicks. Only I YANKED the stick to see if I could pop the wings. Nope, nothing happened. Got the stress groan going good, but at 400mph a hard yank on my stick will not blow the wings off a P-47D.

So I guess you just have to set the slider bars in the game to a gradual acceleration and not all at 100%. I've got mine set to start at 70% and go up slowly from there. At 440mph in a 190A5 I can pull hard back, but not yank, and haul it around pulling about 8 Gs. Get a stress groan from the plane, but nothing breaks off.

MS Prec Pro USB. Only ripped wings a few times, and they were all well-deserved

I have only once broke wings of Dweeb-C, both wingtips actually  
I made sharp dive on a tank and pulled up with 250mph, like 300 feets off ground and I were still nose down, but I leveled  
That while I also lost wingtips  
(nose got up *really* quick)

With F-4u, if you break wings, I'll say that it was pilots error when using full capabilities of its elevators... (whee, talk about good controls)

In P-51 I tested it offline, I had to get +7Gs to break its wings. (I were blackout before wings gave up, though, weren't just wingtips, but eeverything from the root of wings)

In 190A-5, it was sort of hard to break wings (though, doesn't 190 have thicker wing than P-51? might give extra durability)

What more surprises me is that Spitfrie has tough wings to cut when compares to P-51 (and historically those weren't that tough to damage with high G pulls)

In 109, you can dream about pulling enough

Fishu:

I've pulled wings off a 109 three or four times  

Must be my extraordinary skill.

All the times, it left me not pissed, but laughing and almost a little proud

Let me emphasis that in all the encounters that my group has had with this anomoly in the F4U's, 3  things were common:
-Speed was low, 250-300 TAS
-G meter showed 2 G's or less.
-A GENTLE climb out was  being executed.

I've experienced the same thing Rip.  I've noticed that the wings rip on my airplane only after that wobble in pitch occurs.  Each case for occurs low G's in a shallow dive, albeit high speed dive under 400 mph.  The wings rip if I change any stick pitch input while the airplane is wobbling.  Could the wobbling be multiplying stick input by several factors?  If so, recovery would be extremely unlikely before the wings rip off due to over-G conditions even though the airplane is not "pulling" constant positive G's.

Been looking for a recovery technique, haven't found one yet.

I've found only one recovery technique, ALT-F4.  

Thanks for posting your problems as well, guys, maybe it will shed enough light to warrant a look-see by HTC.

Pyro-1.04:"Made a change to how we model airframe overstress. This fixes most of the unanticipated overstresses, particularly on the wings."

Maybe this addresses the problem.
