CC3D STM32F4 based flight boards

No one? :disappointed_relieved:
I just upgraded to the new 3.9 stable and still ā€œNo RC receiverā€. I found this pointing me to pin 5 of the ā€œRC INPUTā€ port of the Revo, but Iā€™m still not getting any RC signal. I tried two receivers that work fine with a Pixhawk but I canā€™t get the Revo to see any of them.
