I did a few more test flights.
Actually you don't need to put 1000 hits in - usually it goes in the slow death circle at latest around 500 hits. Still, that's an awful lot.
If you pump after 500 hits more into it it often doesn't change a thing. Still stays in once piece, and slow death circle...
For the fun of it I tried it once and continued shooting:

Important is to shoot at convergence, if you do so even from six you can get the catastorphic explosions - if you hit the right spot:

So I changed the ride, took the 12.7mm guns of the G50. Still no fires. However the nose guns allow for much more accurate hitting in one spot and if you concentrate your fire into one wing it goes down quick and easy:

In the second G50 attack I needed 41hit in left wing, down she went.
Changed the ride again and took a 110. First used MG and cannon, and finally got my fire, center fuselage:

So decided to use cannon only, got my fire again, outer wing this time, but needed 25 hits:

Will do more 20mm tests to check how many hits needed.
Overall it seems that only 20mm can set the thing on fire and that might be the difference with the MG's.
I will test as well the G50 in more flights against the He111 as it easily sets other bombers on fire.
