Is 190a5's turn affected significantly by adding outer cannons & if so do Dokgonzo's performance figures relate to 2 or 4 cannon planes?
Thank you.

Whisky, the 190A-5's turn might be affected as much by fuel load as the two extra wing cannons.

What's more, why do you want to flat turn it?

I'm sure it makes some sort of difference although I doubt it's noticable (I always fly 190's with the biggest gun package available). Since they are internal guns it won't have the drag effects of hanging gondola's on a 109 for instance. Fuel load would have a larger impact for sure.

I'm not sure how the Doc Gonzo tests were done.

Not every turn is a flat turn.

But, but... what? Flat turn performance is everything!

To get any accurate measurement of turn radius, you need to turn flat to keep a constant speed. Unless your ASI is computer monitored, I can't think of any other way to do it...

And this post was about Gonzo's performance charts, or were you just stating a platitude for kicks?

the outer wing cannons are FF's anyway, so not worth taking. Might as well take a couple of spud guns in the wings.

Anaxogoras, a flat turn at a constant speed and the time for one revolution is enough to solve for the turn radius with some very basic geometry.

Yes, what you said is equivalent to what I said.

Up close they work just fine.

They're no use for long-distance shots but they add that extra punch in close.

I never take outer cannons as Furball says & low rounds, but Dokgonzos lethality figures for a5 are for the 4 cannon version. I just wondered if anyone knows whether the extra cannon have an adverse effect on performance and if DG's other charts are based on 4 cannon model. The reason being is that my gut feeling is that the a5 turns better than his chart suggests, but it is only an impression based on the little experience I have. If I'm right, this could be an explanation. It may just be it "feels" to turn better because the rapid roll rate initiates the turn quicker than most planes.

Thanks for the input.

I feel that the 190 20mms are massively under-powered, so I never take a 2 x 20mm loadout if I can avoid it.

Even the 4 x 20mm A8 version is hopelessly under-powered. I always take the 2 x 20mm and 2 x 30mm loadout and have much greater success with that.

Just a placebo I think Xasthur.. I manage fine with the 2x20 and 1x30 in the 152. They are definitely less powerful than the Hispanos, but not anemic either. The only plane I find a bit underpowered is the D9. But you just have to stay on target a little longer than usual. There's gobs of ammo, so it's not that bad.

Agreed. I think the notion that deleting the MG/FFs improves performance is largely in the mind of the pilot. The plane is a pig in a dogfight, anyway, so you want the maximum firepower for when (if) you get a chance to shoot at someone.

No.. MGFF is definitely ballast worth removing unless you're going to do nothing but BnZ slashes, where even there the weight becomes useless ballast after much less than half the sortie, which is the tolerance threshold I think best applies.
