"You can see the wind gust at around 8 seconds when the cameraman is blown forward."

Dr Adrian Evans replied to Todd's discussion Pixhawk on a DJI S900
"Have had similar - my conclusion was wind knocking the baro out and the system not realising it was falling. This is common for me. So much that I have a switch I hit if dropping begins that puts it into loiter and with the throttle set at just…"

"Hi Mike,
It's not something I've been bothered about doing I'm afraid - I see it as a roll cage for my camera in the event of a crash and so leave it down

best

"Hi Glenn,
It's a S1000 with pixhawk apm 3.2 I played with using the piksi rtk gps but it drops out too much to be stable at the moment so flying with the normal 3dr gps+compass

I'm hanging a Sony A7r with a nikon 150mm lens from the mounts and…"

"Hi Glenn,
I'm using default PIDs and have a Sony A7r mounted with a 150mm lens under my s1000. using 1/5000 shutter but images are sharp as you like."

"Hi Glenn,
I did do an auto-tune and it was rubbish - became extremely twitchy - so yes - back using the default PIDs and now have around 40 hours of fully autopilot flying with those settings."

"Thanks Elvis, In fact I use the RCtimer 7S power module. And I take the suggestion back!

It would be a really bad idea to not have the feedback on juice left - I was flying out in Kenya with my setup last week. Here in the UK I was getting 18-20…"

I'm trying to get my copter to use input from a rangefinder rather than the barometer during auto missions. I have a lidar-light with a max range of 40m and am flying at 10m. The lidar provides alt measurements via the sonar-range status and these…

I have a problem with altitude during auto missions. The system takes off to the correct altitude and then during the missions slowly descends and then ascends towards the end of the mission. really strange. The sonar is a bit noisy but kicks out…

Dr Adrian Evans replied to Todd's discussion Pixhawk on a DJI S900
"I haven't done an autotune. In this video I thrashed it a little to see if it was stable enough for the tuning. I think it is very stable. On Friday I flew in alt hold and it worked just fine and then I flew in loiter. Did an RTL and a short auto…"

"I just flew a s1000 fitted with a pixhawk for the first time today. That seemed to work fine so I shouldn't see why you would have a problem with the s900


log attached that matches video clip

Dr Adrian Evans replied to Todd's discussion Pixhawk on a DJI S900
"Couldn't you power the esc system built in using a 6s battery and the pixhawk with a separate battery and not have to worry about the current - obvious downside would be lack of telemetry on how much juice is left for the motors. Am I missing…"

Dr Adrian Evans replied to Rob_Lefebvre's discussion Helicopter Vibration Levels
"These are my latest vibration logs. I've mounted my pixhawk inverted using the supplied pads on my trex 450 plus. I made a CF base plate that slots between the landing gear and covers the base.

The X and Z look great but the Y is worse - probably…"

Hi allI'm wondering what the latest is on throttle control through the apm for nitro/gasser powered helis?My current thoughts on controlling the throttle are to have my channel 7 (I've mixed CP to Aux2 - which is channel 7) go into the throttle in…
