I have a Pixhawk 1 flight controller connected to a Turnigy TGY-IA6C 2.4Ghz Receiver. When making throttle inputs on the transmitter, the inputs show up on Mission Planner. However, when starting up the drone, an error message of "No RC Receiver" shows up.
What are the causes of this issue and how does one fix it?
For reference, this is the flight controller
