Ok due to the intense debate i did today some testing with Mojack2 in the training arena.
Circumstances were the following:
Mojack2 flew a B17 as tgt plane
I made 3 sorties:
1. in D9 convergence 300 yrds
2. in A8 weapons, 2x13mm + 2x20mm, convergence 300
3. again in D9 with 300 yrds con
In my 1st sortie i flew the D9 in on the B17, and started firing at 750 yrds distance with the 20 mms only (distance Mojack saws was always about 200 yrds more, all distance posted below are from my point of few, for Mo's view add 200 yrds).
1st pings were noticed not before getting into 500 yrds range. The B17 did not have any notable dmg before atleast 20 pings from the cannons.
So i started the 2nd sortie.
At 1000 yrds i fired just for the fun, but Mojack answered "Hey i heared pings". So i throttled back and zoomed in as far as possible.
I was able to hold the distance between 990 and 1000 yrds. I started firing, with a small elevation above the tgt. And started firing with 20mm, and i scored hits, not randomly but regulary from all of my short bursts.
I than switched to 13 mm and yes no problem to hit a B17 at 1000 yrds (this were 1200 yrds for Mojack).
I than closed in, it was no prob to hit that B17, and before getting under 700 i killed the B17.
Now i switched back to D9, which should have the same guns as the A8.
I flew to 1000 yrds distance and fired with the 20mm only. Mojack was to report any ping he got, but nothing. I changed elevation above tgt, no hit. I startet a long 5 second burst and move the plane slowly through the elavation, till the B17 disappeared behind the nose. No hits were registered by Mojack.
After repeating this about 4 times. i Switched to 13mm and directly scored hits, without a huge elevation above the tgt.
Now i wanted to find out when the 20 mm would start to hit.
800 yrds: 2 pings from a long burst (4-5sec) with a high elevation.
600 yrds: regular hits with the same elevation used in the A8 for 1000 yrds shots and hits
up till yet Mo's B17 took about 20 hits without any dmg noticed in the dmg report
400 yrds: hits are more regular at 350 they still spray over the whole span of the B17s elevator
at 350 finally after about 30-35 hits the B17 lost both elevators (horizontal stabilizers) and was dead
This shows to me, that there is a difference between the MG151 on the D9 compared to other GE planes. It seems the Shells spray more and fall much shorter than in the other FW.
To me this proofed that the D9 guns are different. This will be my last comment to this discussion and my opinion will not be changed by any arguments u bring in. Test parameters were all the same. And the results can only be explained with screwed up MG151/20 on the D9.
