Usually, when I power up and begin running the Zephyr with legacy, it works fine for 15 minutes. After that (running the same loop) it loses the signal, stops running, and then only works in conventional. When I turn off power, wait a few minutes, and turn power back on, it still only runs in conventional. If I turn off power and wait a few hours, it may then run under Legacy for another 15 minutes before it loses the command signal.
How do I fix this?
