Met a guy at the local park who taught me how to tune PID loops by feel
I was at the soccer field off 5th street last Sunday messing with my 5 inch quad when some dude walked up and watched me crash for 20 minutes. He handed me his transmitter and said try my rates instead - it was like the drone finally listened to me. He tweaked my P gain down by 15 points on the spot and it stopped that oscillating wobble I've been fighting for weeks. Anyone else have a random stranger fix a problem you'd been debugging for months?
