Is it possible to use Autotune with a Pixhawk, then replace the Pixhawk with an APM 2.8 and use the Pids from the Pixhawk. The autotune with Pixhawk and 3.5 is just SO much better!
No. It is not possible. The APM can only run 3.2.1 and the scaling and attitude controller is totally different from 3.2 to 3.5.
Ah well, Need more Pixhawks then. I did wonder, some of the Pids from Pixhawk autotunes are much higher than ever seen with APM. Thanks for the reply.
