Hello, 

I am attempting to integrate Hitech UAVCAN servos onto either a Pixracer or Control Zero FC. Using the latest firmware and configuring the appropriate parameters (according to various documentation from HiTech and Ardupilot) I have had zero luck getting the zero to respond to any FC servo functions. Is there currently support for this on these FC? Am i completely out in left field with my question? Any information is greatly appreciated!

Hi, we only support ModalAI products on this forum. Have you seen the PX4 support forum and Slack? That might be a better place to start: https://docs.px4.io/main/en/contribute/support.html
