My GPS has gone defunct from my 4 years old Pixhawk. I have been looking on the web but I am a little unsure by what to replace it. The GPS I have is a 3DR GPS with Compass Kit, with a GPS DF13 plug for the pixhawk and an I2C cable/DF13 plug for the…

I am flying a Tarot 650 frame with a Pixhawk autopilot for some time now. I have autotuned it and it flies well. Since two weeks it flies "jerky". The motors de-/accelerates suddenly and the whole thing kind of jumps through the air. I can fly it,…

"Interesting. What is its weight?"

Rnold replied to Rnold's discussion Mission planner logs: how to analyse multiple graphs?
"Ah, and me thinking it was some English idiom I didn't understand :-). What exactly did you mean? I do use APMPlanner occasionally but I mostly use MP, it is a little "easier" to use. But this logfile interface will certainly see me using APMPlanner…"

"Thank you very much: this is what I was looking for. As far as I can see now, APMPlanner 2 has much better log file management controls compared to Mission Planner.  Thanks for pointing me to it!"

In mission planner I try to relate multiple items with each other, for example acclX and barometer pressure. All I see are two straight lines because their scales are too far apart. Is there a way to have one graph assigned to a left scale and…

Rnold replied to Rnold's discussion Is it possible to use a BEC for stable 12V power supply for FPV?
"I had not considered that. Thanks very much for pointing my attention to this, I'll try order a new battery to test this."

Rnold replied to Rnold's discussion Is it possible to use a BEC for stable 12V power supply for FPV?
"Well, I use 3DR FPV gear. That appears not to be able to stand the voltage fluctuations when connected to a powerline that feeds some powerfull  motors as well, something I understand when I see the voltage fluctuations in the log. I understand your…"

Rnold replied to Rnold's discussion Is it possible to use a BEC for stable 12V power supply for FPV?
"Let me rephrase the question: does anyone power his FPV from the same 3S battery as where the motor is powered from? How do you get stable 12V? Do you use BEC's or is there another way (apart from using a separate battery)?"

I am building my new Tarot 650 and have started experimenting with FPV which I bought from 3DR. I power my FPV camera and transmitter directly from my 3S battery. The image is transmitted correctly but as soon as I start the motors the receiver…

Rnold replied to John's discussion How / Where do I start with MavLink?
"Rolf Blomgren published an article on how to send telemetry to the taranis. He did this by using a Teensy (Arduino compatible) reading the relevant telemetry data from Mavlink. I was able to read and adapt this code to my own needs and to make the…"

"I received my "pry tool" today and in just some moments I could remove the plugs from my pixhawk. Maybe 3DR could supply a pry tool with each APM sold. And provide a link to the video Felix Messner posted. This really makes a difference.

Thanks for…"

"Thanks for the tip! I ordered them immediately but this is highly qualified high-tech electronics and may not be exported to Europe :-D. I ordered them from somewhere else. Weird."

"Pity I only saw the 3DR video. Tried it myself and this is indeed very simple. Same solution as Harry and Paul suggest. Thanks a lot for the link!

@ Harry, I saw your tool. Are you sure your dentist doesn't use screwdrivers from the local hardware…"
