Was flying my MA2 this morning and as I got to around 2200 feet away from me the display started getting very broken up and freezing. Started coming back towards me and all was good. Went away from me in the other direction and same thing happened at around 1100 feet. Got a message to adjust antennas. Did not seem to help and screen froze. Adjusting antennas did not help. I expect more distance with the Smart Controller.
