Please check the Model
Did several flight test in this ac. It was capable of diving at various throttle settings over 500mph actual. I started my dive test from between 13k and 19k. In all test the ac did well over 500mph actual in a dive prior to loosing a rudder and in every case I was able to pull up and maintain flight. In one test I had it up to 600 mph actual and 550 indicated before I lost parts. I did have a rider in one of the test who assures me he will post the film.

if you think it's a bug, why didn't you post this in the bug reports section?
-
Didn't the M5 have substantially increased skin thickness and structure strengthening over previous models, specifically to increase dive speed?

Yes, something like 600 or 700 additional pounds of aluminum in the skin to allow for higher dive speeds. I don't recall to what speed that increased its allowed dive speed though.

I wonder if a certain FM-2 has been unable to escape (from considerable altitude) by diving :lol
-
I have a problem with that to because i have had a zero keep up with my F4U-4 a fews times by diving on me

How fast was your F4U-4 going?

WTG you can even catch a set of B17 diving in formation @ 525 mph in a zeke m5 !!! :eek:
But of course they can still kill you at 1.5k out doing it .....

Irrelevant, because F4U-4!

It's not irrelevant. If the F4U-4 had just finished up a fight and was just starting to build speed from 250 the zero would have no trouble catching him if he dove in at 400.

actually those few times i was going about 400

A6M2 can dive past 400mph. A6M5 can go well over 400mph, though it handles like a pig at those speeds.

here is the catch, you can roll out of the zero's trajectory easily at high speeds

Yes it did. The max dive speed achieved was 460 mph . Jiro Horikoshi in his book Eagles of Mitsubishi The Story of the Zero Fighter . States that performance requirements demanded by the IJN pretty much limited max dive speed to 460 mph . Though in his book it is stated in kilometers rather than miles per hour . I will give the exact pages when I find my book again. I am finishing moving . I am a little disorganized normally ,during a move it gets worse. Surfinn I will post the film if needed. I think the important part is posting the designer of the planes quotes. It is very easy to reproduce your claims as to dive speed achieved. I will make that the number one priority. All of your test speeds achieved are well in excess of what the plane was able to do.

Just keep in mind that what a pilot manual and/or manufacturers suggested safety limits may be...that does not always jibe with the absolute mach limit of the airframes structure. 460 TAS mph is a good yardstick perhaps because the roll rate is uncontrollable at that speed and its elevetors will be stiff as well. It's telling operational pilots to beware of exceeding that but the airframe will still take it past that speed.
Went to the DA and dove it with film on. At @460 TAS the controls were all but useless. It completely broke apart at 558 TAS and to get it there I needed to trim down.

I've read comments by Japanese pilots who did take their Zeros past their rated limits. Always hard to decide where to set things like that in a game.

My problem with that is this. Pilot accounts about aircraft performance are not acceptable for plane performance in game . For example the Brewster. Also there is plenty of accounts of Zero's folding a wing up when in a dive. Many of those as pilot skill level fell for the IJN. I will devote some time to putting books on shelves tomorrow. I want the exact quote. It was not handling but structure that Hirokoshi was talking about when discussing dive limits.

If you are going this fast in a Zeke you are doing it wrong.... :D

Definitely the wrong tool for the go-fasty job. Plenty of others in the tool box for that.

Highest speed I ever got a kill in an A6M5 at was about 425mph. I didn't really have control, but as my nose was forced up it passed over the Spitfire Mk IX I was pursuing and I opened up on him, blowing a wing off.

Test it Karnak you will see.
