Ive bought 2 weeks a go my EZUHF on readymadrc.
Im using the EZUHF conected on the trainer port of my 7c 2.4 Futaba.
most of the time, I turn on the controller and everything is allright. But some times, I turn on the futaba and the display does not appear. I can control the plane, everything works and I can take off. The only problem I have when this occur, is that the fail safe does not work.
Some times 10 min later, the display appears. But on other flights, not apear.

Need Help.

Thank you
