First of all, I'm loving this module so far and it's incredibly well-made. ;)
I ran into a problem during the ARC system training mission that I cannot quite determine whether it's a intentionally modelled problem with the ARC or its a bug.
I set up the ARC to follow #3 beacon and start flying in it's direction. I have a solid morse code signal and i keep around 3000m altitude. I do not reach the beacon though. The needle kept pointing ahead of me and didn't change its mind until I had reached the southern coast.
Looking at the map in the kneeboard I could see that I should have reached the beacon long ago. I tried resetting the beacon and now it started leading me inland, and so much off course that I didn't hit the trigger for having found the #3 beacon.
I found that when I aligned the Mig21 with the compas needle for the ARC, the needle would often "get stuck" and follow the planes changes in direction. That meant that I could drift as much as 20 degrees off course, and the needle would still say that I was going in the right direction.
Anyone else encountered this problem?
