spit 16 gun convergence
« on: December 13, 2008, 01:11:17 AM »
I need help with cannon and gun convergence . I have to be at d200 to get decent hits on target at d400 cant get a hit at all. But can get decent hits on target in the la5 at d400 quite easily. Could some one give some ideas to help me improve my hit rate in the spit thaks :salute

The La5's guns are nose mounted making convergence less of an issue.

Convergence in wing mounted guns really depends on where/when you fire on a target. In a a/c with faster closure or an a/c with taters, I'll set it at 225. For convergence with 50 cals in the wings, I set it about 375. Wing gun convergence is entirely personal preference imho.

Most of the time, I'm in a P38 which has nose mounted guns as well.

The mounting of the guns makes the difference. The La's cannons are nose mounted, making onvergence settings less of an issue than with the Spit's wing mounted ones.

When shooting at a target 400 yards away, the nose mounted weapons will be tighter grouped:



I would suggest  putting convergence back to a more reasonable longer range (like D300-D400 for example) - or wait until your target is close enough.

set the 20mm and .50cal to the same convergence, and that should be where you take most of your shots. I'd start with 300yd and bring it in when you find you're taking shots closer.

Since the OP says he can't hit much past d200, I think he should set his convergence in tight, like <250.

No, he said he just can't hit at D400 in a Spitfire, while in a LA he can. And the reason for it is his convergence being set too short for D400 shots.

Where did we learn that?  The OP never said where he sets his convergence in the Spit16.

Just because your convergence is set too short doesn't mean you can't hit from that distance, rather your hits won't be effective.  When I fly the P-47 I regularly get hits at 600 yards and further out, even though my convergence is set to 400.  I have it at 400 yards because that's where I tend to kill the most, but it doesn't prevent me from shooting further out.

Bullet dispersion and imperfect aim is more than enough to make up for convergence being shorter than the target's range.

When firing at targets not at convergence, fire slightly off center to score more hits.

I think when it says your 400 out it's actually somewhere between 500 and 301 and when it first says your at 200 out from target it's actually 300


I take a lot of shots when it says 400 but not normally in any of the spits that carry 303's. I like to get a little closer and as soon as it says 200 I start firing. I'll try to keep my target in the 200 range using throttle management.

The 16 guns are a little different. Having the 50's maks it possible to take longer more heavy hitting shots. The 50's are on the inside and shoot long and straight so I set them out to 325-375 giving me a good convergence pattern at 450 and below. The cannon being farther out on the wing but not so far that i need to set them out longer I put at 275-300.

I've tried both set ups and like 350 for the 50's and 300 for cannon best. (not shown in pictures) Both cannon and 50's cross at about 250 and again at 325 spreading out across the targets wings from there. The 50's I can still use effectively at 450-500 forcing them to turn.
