Mark Brummett replied to Don Roberts's discussion Mission Planner 1.3.43 problem in ArduCopter User Group
"And then looking at it, maybe they didn't.  Or it wasn't very clear."

"I believe that info was also in the release notes.  Most people don't read them anymore I guess."

Mark Brummett replied to Tom Kopp's discussion Pixhawk with low KV motors unstable/crash
"And as I noted in that ardupilot thread, if you want good, worry free ESCs for low KV motors on heavier rigs, the Hobbywing Xrotors work great.  And no, I wasn't paid for that.  :)"

Mark Brummett replied to Marco C's discussion multi tasking UBEC in ArduCopter User Group
"True, but if the flight battery goes dead it doesn't really matter if the FC works if props aren't spinning."

Mark Brummett replied to Marco C's discussion multi tasking UBEC in ArduCopter User Group
"It would depend on the amp rating for the UBEC I would think.  The link to the one you've provided indicates 7.5A, I'm going to bet that would probably be just fine.  You just need to find out how much each draws under the maximum load.  If it's…"

Mark Brummett replied to Eric's discussion Can't download logs with Pixhawk?
"Sounds like a corrupted SD card.  First, try getting the logs by putting the SD card in a PC.  If that doesn't work, it should tell you that you have a corrupted card."

Mark Brummett replied to Cool Dude's discussion Nitro Heli Vibration!! Need help.
"This is a gasser, right?  Nitro?  Any gas/combustion engine vehicle will likely be inherently vibration prone.  I haven't heard of many people using gas powered helicopters/multicopters without having to get really serious about vibration damping.…"

Mark Brummett replied to Rob Summers's discussion Done flies fine in stabilized mode jerky in Loiter and RTL.
"THR_MID sets the midpoint in Stabilize.  Loiter will ALWAYS be around 50 percent because it uses the altimeter to find the hover.  Stabilize doesn't.  You need note where on the throttle throw in percentage that the craft hovers in stablize mode.…"

Mark Brummett replied to Rob Summers's discussion Done flies fine in stabilized mode jerky in Loiter and RTL.
"Have you calibrated the mag?  The acceleromter?  How do you have the FC mounted?  Which FC?

Also, if you've done all the above, if you change motors and it flies wrong, it's likely because the PIDs are now not valid.  You change the drive method on…"

Mark Brummett replied to Chris's discussion Why aren't there more single rotor drones out there?
"Setting all the arguments about safety, speed/torgue/blade size aside, the one thing that multirotor (especially those with more than four rotors) vehicles have that single rotors do not is redundancy during motor failure.  If a motor fails on a…"

Mark Brummett replied to Nihal's discussion EKF and Vibration monitor displays are not updating
"If you are enabling AHRS_EKF_USE, then you are using firmware 3.2.x and below.  I understand that the EKF and Vibe options on MP will only work if you have firmware 3.3.x and above installed.  In copter, EKF cannot be disabled by that flag."

"Damn.  This would have been nice to know back in July 2014 when I bought it!  Oh well..."
