Hello, I'm a new IL 1946 player and have a problem I need help with.

In my IJN campaign I've been told to climb to 10,000 metres in my J2M to kill a B29 bomber. I use autopilot and fast forward time because I was hoping it would sort out the engine to let me climb that high. When I take autopilot off at the hieght of the bomber smoke comes out my engine, i loose power and start descending.
How can I manage the plane so it can fight at those high levels?

You need to engage your supercharger, check your key card, should have it listed there, I think the default is "S". You will need to make sure thats set, or your not going to generate near enough power to hold that altitude.

i dont know if its automatic on the j2m but if it isnt then you'd also have to reduce the fuel mix!

Thanks guys both those fixes worked and that B-29 hit the ground with force http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif

Of course now I'm stuck on the next mission where its just 4 J2M Raidens vs an entire bombing flight of B-29s. Even doing maneouvres like attacking head on and from below result in my plane loosing controls or blowing up. I don't think its possible for japanese fighters to take on these bombers and return alive...

Ideally, avoid attacking from below. If you have just dived down and are on your energy based zoom climb you can do it, but otherwise it's not a great plan. Instead, if you attack from above and to one side, say at 4 o'clock or 9 o'clock high, you'll be putting the gunners in a harder position. They'll be tracking you laterally, vertically and with forward motion, too.

If you are new to all this, think about energy. Retaining energy makes any attack better and more survivable.think of yourself as riding a bike. When I first started I had no idea about energy until someone posted an analogy with a bicycle. it went something like this.

You are biking uphill to attack a bomber which is situated at the top of the hill. No matter what, you're going to have to pedal a lot harder and will still lose speed gradually depending on the length of the climb. The gunners will be able to watch you puffing and panting, straining to approach them. They can pick you off at their leisure (relatively speaking).

However, should the bomber be at the bottom of a hill and you start at the top, you can *freewheel* down and still pick up heaps of momentum (energy). This extra speed plus the ever diminishing altitude difference makes it harder for them to hit you.

That said, no matter what you do, the AI gunners are still too accurate.

I didn't know there was an offline J2M campaign, but there is a very similar 'Single Mission' of the same scenario: Some J2M's with a Ki-100 escort attacking incoming B-29's @ 6500 M and with a P-51 escort.

If you're in a J2M5, you have a 3-stage supercharger, and need to switch at 2500 & 5500. You need to lean out your mixture at bomber attack altitude or else you'll trail black smoke and suffer loss of power. 80 percent at 6500, and lower the higher you go. Watch MAP and RPM and you'll see what the engine wants. I've never been successful at 1st until I managed my energy better. Rather than attempt to climb well above them ( where distance dictates I'll be higher but slower ) I line up my attacks so that I'm really moving and level or slightly below them; make my firing run and continue in a slight fast climb till I'm higher, reverse and repeat. Keep your rate of closure high and avoid dead-6 attacks. Rake the wings and empennage. You might not get an immediate kill, though they'll go down and you'll get a delayed one.

Got 3 B-29's before my ammo was empty and made it back to base to live last flight ( though P-51's were milling about the base attempting to strafe me as I was shutting down my engine after stopping )

Always tricky to take on B-29s...they are tough and very very well armed. With a Japanese fighter you can hope for a single headon pass or maybe a second before RTB.

that bike analogy is actually very good http://forums.ubi.com/groupee_common/emoticons/icon_biggrin.gif
I remember I was flying a b29 online at about 8k, and had a J2M trying to catch up to me from my very low 6... he'd forgotten to lower his mixture too :P
anyway, he actually managed to get a few hits on me, which was quite good of him, then he got blasted to bits by my gunners.
He tried to come after me again... persistant little fellow, with the same results. I didn't see him again after that.

Slightly off topic here, but does anyone know approximately how much B-29s were actually shot down by japanese fighters?

It's called something like 'Glowing Glory' and you start off in an A6M. After a few missions in that then switching to the raiden made me appreciate its better armour and firepower (not too mention the roll rate)
