re-calibrated the esc’s. I did get one flight in stab, but it was hard to control. I have looked at the log and found the vibes/clip were high, so I have re balanced the props but can’t even get a lift off again. any advice?

You are using the wrong firmware for whatever flight controller that is.Some version of a 2.4.8 I suppose. If it’s a Radiolink version too bad for you. Fmuv2 is incorrect. You should flash fmuv3. Then, you are on default parameters so you are starting from square one. There are plenty of configuration and tuning tools around, get to work.

Thank you. now 4.5.3 fmuv3 will not fit on the board. It’s not from radio link.
I go back to 3.6x. Any other suggestions?

Build a custom firmware with anything unnecessary disabled, https://custom.ardupilot.org

Then use Pixhawk1-1M
