I'm in the same boat, got the guts to my new system in the mail currently. (Can't wait to see how she flies!!!) Anyway, I reviewed the documentation file and see that I need to utilize the "dcs protect" deactivation utility. I have Huey, BS2, C.A., A-10 currently. Does the "dcs protect" deactivate all my modules at once or will it give the a choice of which ones? (I need to copy down my BS2 serial # as I cannot seem to find it) Thanks in advance--
