Can't find certain control keys

[Marmusman]

I agree with RASmith1030, this is a simulator...so the answer to questions about flying are usually "what did they do in the real plane?"

Airbrakes for this era of planes were used for dive bombing only. So I do not recommend them.

You can deploy your flaps a bit to slow down, bit do not give it too much flap...they will get damaged. I am not sure what the Combat Flaps setting is for the Stuka, but don't exceed it, i.e., don't use landing flaps setting.

Throttle is the best solution. sometimes a combo of throttle and flaps.

Regarding you other questions, I recommend searching YouTube for some Cliffs of Dover Stuka tutorials....might be quickest way to learn. Did you Arm the bomb before dropping it? Did it explode? There are a series of keys you need to assign for bomb settings. One is to set bombing to "series" or "Salvo." The key commands are near the Arm Bomb command in the key command listings.
