I have some param files from a large (~50lbs) quadplane that I am looking to tune, but they are PX4 files. My question is, how translatable are the PIDs from PX4 to Ardupilot? I have been digging into the code stacks of each to figure out the nuances, but figured I would ask here if anyone knew straight away.
Something I was thinking about doing to compare would be to get a small quadcopter tuned with PX4 PIDs and try those PIDs with Ardupilot firmware and see how it behaved. Would those findings be translatable from a small quadcopter to a large quadplane?
