You can find older Versions under "Changelog" on KerbalStuff.

Can you post a picture of your craft? There is a lot that can go wrong e.g. radar with limited view angle used, crafts on the ground are not detected...

I had the same problem. To fix it I had to use kerbals instead of drone parts. Crafts with drone parts don't work for me.

I installed the newest versions of the mods I used and it was gone.

He said it in one of his videos but I think it was older.

No, they always have enough electricity (RTGs) and I can use them and shoot without any problem. And a feature request: Turrets are useless against planes flying in a circle (because they only calculate where it will be based on the current speed). They would be more accurate if you use a curved flight path (based on the average of the last 0.3 seconds). I think the mathematics would be easy enough if you use the approximation technique.

I watched the video, tried to reproduce it and it worked. The difference was that I always used drone parts and never put any kerbals inside the defender unit.

Yes, they have radar but should attack when an enemy craft is in sight (up to 3500m) without the need for a radar (only guns).

I have s similar problem DEATH92a. The pilot-AI works but guard mode refuses to aim or shoot. It just does nothing. Everything else works fine.

I have a bug with the guards. Guards on the ground don't attack air targets, even in range. I use Linux Mint 17.2 and start KSP with " LC_ALL=C ./KSP.x86_64 ". Ferram Aerospace and Stock Bug Fix are installed too.
