Great advice and much appreciated.  I'm certain that I downloaded the "Agile Helicopters" from Armaholic written by Raven_JJ as the restricted mods were noted on the NAK server as "Rjj agile Blackfoot/Ghosthawk". See  http://www.armaholic.com/page.php?id=25103&highlight=RJJ%2BAGILE .  The mod was for a more realistic flight but the reality is that I don't pilot anything on any server.  I respect you and the admin at the NAK server very much.  I'm glad that they watch for mods that might give others an advantage which is what ruined the run-n-gun COD, Battlefield and all of the others that have been lost to the cheaters and their aimbots. I take to heart all that you've shared here and I completely understand.  I did find under my "Heli" internal folder all of the files that started with "RJJ" and deleted them, about 15 files that I put there 2 or 3 years ago.  I haven't tried to restart the ARMA 3 game yet but you're probably right, I may have to completely uninstall the game and reload it.  Thank you, again, for your knowledge and taking the time to set me down the right path.   :-)
