Hi Paul,

Please follow the steps from this post:

Radio control not detected on Navio 2

Hello, guys! Could you please post the output of cat /sys/kernel/rcio/rcin/ch2 and move throttle stick up and down to make sure RCIO processes data? And also Could you please post the output of sudo update-alternatives --display arducopter? We need to verify that navio2 binary is selected. It should be something like this in case of a quadcopter: [image] Mind the navio2 in the link!

Also, would be good to see the photo of your hardware setup.
