Not an issue. TSA (in the states) never hassles me when I travel and I have 2 units + ST E3 RT. All the devices with radios/wi fi etc. that people carry every day they could care less about triggers in a flash unit.
I seriously doubt the TSA would even have a clue what those items were, much less even consider they had radio capabilities.
Besides, they're a bit too busy lately with "security theater", and hassling/groping little girls in wheel chairs.
