I've built quite a lot drones with APMs 2.8 but it's my first time with Pixhawk 2.4.8 and I got the following problem. Drone throttle response is like it's not calibrated, even though I've calibrated ofc. Drone takeoffs with minor increase in throttle (less than 10%) and max throttle is comes at about 50%. Of course I can't get it to land softly cause there's no throttle value that brings the drone down other than 0%. Also drone wobbles like crazy. I've played with PIDs, and set my MOT_THST_HOVER to minimum and the difference is less that noticable. I'm thinking that it might be incompatible ESCs so we already ordered some blheli normal ones that I've already worked with while with APM. But I just want an extra opinion.
