I've been trying like mad to add bombardier positions to the other stock CFS3 aircraft that do not have them (but should): B-25H, B-25J, Ju88-C, and the Ju88-P. It seems tragic that these planes cannot also do accurate level bombing when neccessary.
I realize these later-model versions have massive cannon and machine gun armament in the nose that, in real life, actually prevented bombsites from being installed. In my humble opinion, however, I think 1940's optics technology was advanced enough that they could have found a way.
So far I have been unsuccessful. I have been trying to add these positions by manipulating the aircraft's XDP file (see picture below). Changing these files is also a great way to add more useful armaments to aircraft, such as torpedos for Allied fighters!

Now, you can successfully add a bombardier postion to the aircraft by putting in the highlighted line of code above, but when you change to this postion during gameplay, the view is not the bombsite, but one of the machine-gun positions, or some other distorted view from the pilot's perspective... some quite hilarious. I've tried many different variations of the 'View="3"' line, but no luck.
Any suggestions? Has anyone successfully accomplished this, or even tried? It's my feeling that because the aircraft model itself does not have a glass, and therefore transparent nose, it may be impossible.
My apologies if this post should actually be in one of the aircraft design forums.
All the best.
