Bf 110 cockpit, Wahlschalter and bomb load.

Found it.

bombload - breaking.jpg

First position [a] states normal C-1 to C-4 variants (without bombs and additional fuel tanks)
Second position [b] states variants with only strengthend main gear and not strengthend tailwheel.
Third position [c] states variants with strengthend main gear and strengthend tail wheel.

I think air resistance for propeller by standing A/C with 12:00 pitch is not modelled jet.
See 9. on the left page.
Will check it now.

I think air resistance for propeller by standing A/C with 12:00 pitch is not modelled jet.

Looks like it is modelled. But 25-75 rpm to low after warming up to 50°C oil and 60-70°C water temp.
I only reached 2175 rpm on both engines, but should reach 2200-2250 rpm.
so ~ 50 rpm are missing.
For everyone who want to test it too, slowly warm up with 800 rpm and pitch 12:00 to:
min oil temp: 40°C
max water temp: 80°C
Set trim to Hecklastig (heavy tail)
Pull your stick a little bit (or eat the grass ) and push the throttle to 1,3 ata and keep it (not longer than 5 min).
Check if 2200-2250 is reached.
