Ardupilot for singlecopter

We've been developing a singlecopter for 2 years. Recently, we are in a severe shortage of human resource and need someone with intensive experience in Ardupilot (with multicopter is good enough, NOT necessary with singlecopter, since we don't rely on Ardupilot's singlecopter firmware) to help fine tuning the controller. You can use pixhawk or pixracer hardware. The task includes: - Test and debug magnetic, EMI interference and other hardware issues (if there is) - Configure and fine tune flight controller to make it hover with GPS ubox NEO M8N - Flight test in different environment and produce report Interested freelancer please provide a proof of your Ardupilot's experience. The total time for this project is 1 month. We base in Vietnam and will pay the flight ticket and (basic) accommodation if necessary. The below budget does NOT include the flight ticket and accommodation, and should not be considered rigid.
