I would love to see the J2M's in AH in what ever variant we might get.


I still think the J2M didn't quite behave in the dives at 350mph+ like the George. The J2M did have the same number of cannons as the George, but only two of them were the Type 99 Mk2's. To smooth up the airframe they switched the outer cannons back the Type 99 Mk1's. I think the George would be better in the dive and still have better punch. Just those two differences for me would warrant its inclusion in AH, making it different than the George.
As I understand it the guns depend on the version we get.  J2M3 has mixed guns like you list and was the most common version.  If we got the J2M3a or, better yet, J2M5 in addition to the J2M3 we'd also get one with a uniform armament of four Type 99 Model 2s as well.

Another brick like the A8 and nobody would fly it, except masochists...  :uhoh

Don't go there in this forum Charge.  :furious


The Fw190a8 IRL was more nimble than the rest of the FW A-series .
It had the same wingloading , due to a improved slight larger , lighter wing design, among other things.
With the GM-1 A8 was an equal in speed to its competitors at low-medium-alt.

50% of JG26s Focke-Wulfs where equpped with this booster-system during the fighting in france following the invasion.
In AH we have an overweight A8 with no GM-1.


This.

Krusty is right A-8 is heavy, but GM-1 would be usless in AH as like krusty said, It was an ultra high altitude boost (which even the luftwaffe never really caught on too)

It would be great if we got the J2M5 as well. Would be very usefull over Japan in 1945 for the FSO and Scenarios.

There was a small modification starting with the A-6, but the extent was simply reorganizing the outboard gun bay to accept the larger magazines and guns and internal stuff for the later outboard armaments (MG151/20s and Mk108s). It wasn't larger and it wasn't lighter and it wasn't an improvement (not aerodynamically, I mean).

Also, the 190A8 never had GM-1, and GM-1 will damage an engine if run below 30,000 feet or so. It's an extreme altitude boost only.

You may be thinking of MW50....  :noid

However, not many A8s had this installed. Many used the MW50 tank to store regular fuel. This is where the AUX tank in aces high comes into play. That's why the Dora doesn't have an AUX (it's holding MW50 instead).

The 190A9 may have had MW50 in small numbers, but overall it wasn't big for the Antons.

GM1 could be safely used above the engine's critical altitude. MW50 was only tested on an A-4. The power boosting system was extra fuel being injected.

J2M is the only plane that if added would cause me to switch from 190's

According to JG26 war diary volume 2 p265 at least some squad aircraft was equipped with GKM-1 booster system after summer 1944. In that case that should have been the R4 version of The A8.
"It raised the fighters crititcal altitude from 5500 6300 meters ". "Its performance top speed my as much as 36mph at altitudes over 8000 meters "

My ammo last for 6 Lancasters, or one Yak3.

on a side note Charge, that gallery of the Kaisei engine, if you go to the pic on the left, It is an amazing picture of the experimental turbo charger that was equiped to the J2M4

Indeed, looks almost like something snatched from a P47 or P38.  ;)

Maybe it is a copy of an American design? Anybody know?

after sifting through lots of internet BS, It looks like the Kasei 23c engine was only a 2 off  for both of the J2M4's, they never solved the problems with the turbo (most articles hint towards the tubo themselfs being the problem, so I would doubt they were copies) this is a really neat plane that has always been on the back burner for me over 190's, but after spending some time in other japanese rides, I would love to have it in game, one of my biggest hinderances to reasearching it in real life is the lack of info about it + I have only found 1 book about it, which I cannot locate to buy anywhere

I hae just found possibly the best source of information and pictures available on the web and maybe in general aswell of the J2M, it is a 17 MB PDF file, and in japanese, but none the less contains some of the most amazing pictures of this plane I have ever seen

here is a teaser picture of what this file contains:

Thank you.  That had a lot of nice photos, the vast majority of which I had never seen before.  Wish I could read the Japanese though.
