The reason why your planes don't show up is simple: You're missing
a lot of important files.
Please go to the first post of the
release topic and look at the installation procedure for v4.10.1, step one. Download the two SFS files mentioned there and unzip them into your main game directory (were all the other SFS files are as well).
Once you've done that, please go into ...\IL-2\#SAS\STD and
make a backup of the file called ".rc". After that, please open the file (you can do this with every normal editor).
In that file please scroll down until you find the section where all the SFS files get loaded. This looks like this:
[....]
@sfs MOUNT fb_sound.sfs
@sfs MOUNT fb_sound01.sfs
@sfs MOUNT fb_sound02.sfs
@sfs MOUNT fb_sound03.sfs
@sfs MOUNT fb_sound04.sfs
@sfs MOUNT fb_sound05.sfs
@sfs MOUNT fb_sound06.sfs
[....]
At the end of that SFS load-block you'll have to add these two lines:
@sfs MOUNT fb410_clay01.sfs
@sfs MOUNT fb410_clay02.sfs
After that, safe the file, fire up the game and everything should work
