Hi there! Thanks in advance for your time in my help request.
I just finished my DIY hexa. It’s my first experience in Ardupilot. The maiden/tuning flight was some like frustrating 'cause the copter was very unstable hovering. I even couldn’t check yaw/pitch/roll tuning.
I fought all the time with throttle in stabilize mode. It was impossible to keep the vehicle in a certain altitude. The copter required so little throttle to start climbing (two stages on stick), but didn’t stopped. So I needed to decrease (one stage on stick) throttle and it started to lift down.
I tried basic tunig, with no success. After that I needed to give more throttle for start to climbs. But again, with no stable hovering (it doesn’t stop to climb). When decreased throttle, it start to lift down quickly.
I broken one leg from landing gear in one of the ground impacts of copter. I’m afraid of doing advanced tuning and get more damage on this unstable copter. Any ideas?
