"Every plane I've owned eventually nosed in and crashed. I would expect that lens won't last long..."
"Looks like your nav gains could use some tuning. I'll bet you could eliminate that overshoot when you release the quad after dragging it. "
"It doesn't compile for pixhawk today. It would need to be ported to the latest branch to work on Pixhawk. I have wanted to do that for some time but I just can't slot it in."
"I remember my dad telling me stories about working on these tests. One engine exploded on the stand and the compressor stage ended up on the roof of someone's house in Peebles, OH."
"If there was no drone involved, and this was just a bunch of bro's on a frozen lake having fun with legal fireworks, would anyone care? I fail to see how the drone made it any more dangerous."
"I see a booming local battery rental business about to start."
"Awesome!"
"Now's the time to switch over to the EKF by default. I have and have been very happy with it. Congrats to all!"
"Yes EKF is very flyable, but disabled by default. In fact it outperforms DCM.
Congrats Randy on the release!

"Ha, my friend's IRIS is in the bay...."

A stable tune will return to level in stabilize when you jerk the stick suddenly in roll or pitch.
I start with a Stab_P of something conservative like the default 4.5.
Then a conservative Rate_D of .005
Try a rate_P of .1 and increase to give…"

"And BTW, Colin has been terrific to work with and I'm really excited he's here at 3DR!

I spent some time with Leonard last week testing and reviewing Auto-tune. What I learned was Auto-tune won't crash your copter if you start with a stable tune, but it will crash a copter that isn't properly spec'd.
Large copters can easily…"

"Leonard's frame is 3d printed.
There were two bad crashes. a 550 heli didn't have redundant power and looks like the BEC browned out keeping up with the servos killing power to the pixhawk. It flew an amazing first run. It crashed in the second run…"

"Sixty patents? These guys sound evil. Perhaps the drone is a formality and the real aim is to troll the industry. "
"Hi Leonard,
I'd be glad to try and print some parts for you. I have 3 12hour parts myself to print this week, But I could squeeze yours in if needed. Just send me the STL.
