There is a 3.3V pad as part of the Boot pads on the FC where they recommend connecting DSM RX power. My guess is that the RX is dead, but you could try dropping the voltage to see if it behaves any different.
Here's a link to the Femto manual with connection diagrams: http://www.yinyanmodel.com/upload/20161111/20161111094147991.pdf

Ok, so, i got the new receiver installed on the correct 3.3v port. It went straight into bind mode and bound perfectly. I am seeing a connection in betaflight, when i move sticks the bars move indicating a connection both between the remote and the RX and the RX and the board. But when i arm it, nothing happens. I have triple checked to make sure i have all my channels set up right, when i move the arm switch it shows up on betaflight as well as my flight modes. Everything looks good, motors beep when i plug battery in, light stay illuminated on the receiver, but when i hit the arm switch, nothing happens. I give it throttle, still nothing. I assume i have a setting wrong somewhere but i'm at a loss at this point. Watching the build video, im pretty sure i have all the same settings that TJ has. Is there anything else to look for?
