Wow, what a celestial peace!
The reason is powering the Hott-RX with M4 3.2V, instead of 5V UBEC. All mine other modells
RX are powerd via 5V UBEC. The Hott-RX undervoltage warning default is set to 3.8V, so that i
never get a warning with 5V UBEC before. I changed the undervoltage warning to 3.0V.
Thanks for your help and especially thanks for your great work in developing the Hott FW!!!
