I am building my first quadcopter and have just had a hiccup. I am using Pixhawk 2.4.8 loaded with the legacy firmware Arducopter 4.0.6 which I believe is the latest. I am also using FS-i6X transmitter which came with fs-ia6b receiver. I used a PPM encoder to connect to the receiver and connected the cable from PPM encoder to RCIN on the Pixhawk. I am sure, I have connected everything properly. However on Mission Planner I get no RC receiver error on the dashboard. When I power on the transmitter, it also does not connect to the receiver. The receiver does light up though. What could be the issue?
By the way I haven’t binded the receiver and the transmitter as on the box it says it comes pre-binded, perhaps not. Could this be the issue?
Thanks in advance.
