Maybe it's my earbuds or my imagination, but is his video really "essy," lots of sibilance? It actually kind of hurt my ears a little.
@ Jerome Miller - TL;DR
Len, pay no attention to Mitch - he's an asshole. (By the way, I'm in San Diego and I've seen you at SDFM meetings.)
Mitch, would it be rude of me to say you're an asshole? Eh, fuck it, I don't care. You're an asshole. (Try encouraging people rather than slamming them in a weak attempt to build yourself up.)
I have an Autel, and on my first flight I couldn't get the compass to calibrate. I thought "screw it" and launched anyway. It didn't get far without crashing. Thankfully it wasn't bad, just a scratched up propellor hub. I pretty quickly figured out what happened - I was standing on a concrete pad when I tried to calibrate it, and I think there was rebar in the concrete which interfered with the compass. I moved onto the dirt and calibrated with no problem. Perfect first-and-a-half flight. (The first one that crashed doesn't count!)
