Flying and Skip Bombing the Blenheim on Cockpit Instruments

[Redroach]

hey, thanks for your quick answers!
Found out about that second part: you can switch between bomb patterns in the Blen - single or salvo. There is a switch in the Bombardier's position which I use but I think there's a key assignment possible for that, too.

But now the sad part: After being shot down rather quickly this morning while going to our target on ATAG (L5.3 afair) the direct rout, I set up an elaborate great-circle route for the purpose of coming from another direction.
Arriving at Dieppe ( ), turning east there and turning north after an arbitrary distance inlands (at some waterway ^^ ) , I actually made it to the target! Yay! With some corrections when double-checking with landmarks, but still... Yay! Only to find out that my bombs still won't explode, as others have reported here . Damn, I got CoD since release, got angry about a lot of things but I have yet to get a bomb on the ground that is actually dangerous...
Now, I tried everything that's been suggested in that other thread. I set up my own armament profiles on every level (4x250s), and tried the No.27 and No.28 MkII pistols/fuzes so far (level bombing, that I'll try). I try to arm bombs (though it doesn't seem to be necessary with what I've tested), open bomb bays of course, but... still nothing.
I dropped them directly after spawning, while still on the ground, generating a lot of dust - so the bombs DO actually exist. Furthermore, I've just bombed my own airfield on ATAG and I could make out four little craters afterwards, as if the bombs just buried themselves in the ground. Still, no explosion, no smoke.
What am I doing wrong? This starts to get not awesome... especially after 1,5h flight time, as described above.

P.S.:What I didn't test is 11s fuze delay resp. the longest delay available. Maybe it's that? Anyways, I'd strongly prefer instant fuzes!
