Rob_Lefebvre commented on Hector Garcia de Marina's blog post Pilot a "supra" rotorcraft
"Cool.Can you do it outdoors at speed and/or with wind blowing the payload around?"

Rob_Lefebvre commented on Chris Anderson's blog post First pass at a Drone family tree diagram
"Yeah, I'm struggling to understand the message here as well.  This seems like a gross oversimplification of the history.  It seems to ignore the fact, that many of the most successful and influential Ardupilot developers, got their start at RC enthu…"

Rob_Lefebvre commented on Flora Lai's blog post TATTU PLUS 2.0 SMART BATTERY
"Yes, I hope to see wide availability of these batteries in future.  And more sizes!I also designed a UAV around the Tattu Plus 22000 battery, and then had difficulty getting them. 

I would love to see a battery system available which gets us past t…"

"Sort of sounds like intentional sand-bagging."

Rob_Lefebvre commented on Kristaps Brass's blog post Precision of Vertical Maneuvers – It's All About Safety
"Hi Alexey,
You can get much better performance from Arducopter with a very simple change.  Just set a 1 second pause/hold time at every waypoint.  Now the copter will hit each waypoint exactly, hold for one second, then move on.What you are seeing i…"

Rob_Lefebvre commented on Jordi Muñoz's blog post mRo mid 2017 updates
"Yes, choice is always good.  I just caution about broad comments that isolation is not required.

I have an AUAV X2 that is nearly hard mounted on a helicopter, and it's working fine.  And I have a gas powered heli, which needs the entire autopilot…"

Rob_Lefebvre commented on Jordi Muñoz's blog post mRo mid 2017 updates
"Ok, this is what I suspected.  I would say that stating that "vibration damping foam is not required" is a gross over-simplification of the situation, and will not do you or your customers well.

It can work in some cases.  And it can work very badl…"

Rob_Lefebvre commented on Jordi Muñoz's blog post mRo mid 2017 updates
"Really looking forward to the SoloLink.  CUAV is basically already doing this with the HackLink, but I would prefer to buy from a more reputable source.  I strongly advise you to come up with a name other than SoloLink though.But I'm really confused…"

Rob_Lefebvre replied to Mr N.'s discussion Hybrid 4 stroke multirotor
"Yes, too bad.  It's fairly trivial to get 100 hp/L out of a modern 4 stroke, which would mean this thing should be making 3.5hp.  Up to 200 hp/L is possible for a high performance engine, which would return 7hp here.1.3hp is just really low.  37 hp/…"

Rob_Lefebvre replied to Mr N.'s discussion Hybrid 4 stroke multirotor
"I'm also interested in the Honda 4-strokes, but also believed they don't make a lot of power.  The factory power rating I think is only about 1hp.  But I'm not sure what it can do with some tuning.  These engines are popular with university projects…"

Rob_Lefebvre commented on Jimmy Oliver's blog post Phantom 3 No-Servo Cargo Drop System
"Graham, it's quite surprising to see an admin brush this off as "Keyboard Police".  Perhaps you are not aware, but there is a very serious problem.  This is actually happening.  And yes, they are using our products and ideas.  This community should…"

Rob_Lefebvre commented on Kristaps Brass's blog post Comparing Precision of Autopilots for Survey Missions - Pixhawk with ArduCopter firmware
"Pretty good result as expected, and I notice it wasn't a wind-free day either.Would be interesting to see the results if you set a 1 second delay on each waypoint, it could cause the craft to exactly hit each corner and stop, making truly square cor…"

Rob_Lefebvre commented on Chris Anderson's blog post How do modern open source autopilots compare to aerospace-grade IMUs?
"John, good point.  I know we've seen datalogs where the sensors are not performing within spec."

Rob_Lefebvre commented on Chris Anderson's blog post How do modern open source autopilots compare to aerospace-grade IMUs?
"When (or rather if) Honeywell discovered a problem with their IMU, they would issue a recall.Compare that to known examples from other manufacturers who have discovered major issues with flight controllers, they delete user comments from their discu…"
