The KA-50 is not a RAH-66 Comanche. You should plan youre flight with the KA-50 what you want to do before you go. And get some cover where your KA-50 group is as well via TS, a 104th member should know that.
And btw. in RL, AWACS would see moveing vehicles on the road as well. The KA-50 with his turning rotor blades, is a very nice radar contact in RL. :)
Edited for Ivank, I was pointing on a RL situation anyway.
