"just to go to the interesting thing, i get nice altitude hold (soft 3.0 rc6) for a while, ad it goes full throttle at random moment. I had 3 min hold and throttle up then and also a 7 min alt hold before it tried to fly away...

Yesterday the quad-copter started to twitch. At first i guessed that one of the motors has to be going bad. After I looked at logs, I found out that input pwm is horribly amiss. The pich input is…Continue

Today I was playing with autonomous Takeoff. First test was with remote, to see if everything is in order. The second and third tests went full Auto without any RC control and were complete…Continue

Arducopter rotating in loiter.

Yesterday I was doing a second flight with a new quadrotor frame and had a rather ok loiter for stock pid settings. For about 13 minutes loitering went very well but then the quadrotor started…Continue

Past month, I have been working on OpenSource RC remote like OSRC but with less PIC, less closed source (as they were a bit when I checked the last time) and more developer friendly. The need for…Continue

Markus Järve commented on Andreas's blog post Drone shot down by police"Idea was good, i agree that filming such events must be done. Air gives more ways and less danger to the guy filming. BUT as the video making was done, It was quite careless. Not only from the crowd safety but also from the not getting shot down…"
Sid replied to Markus Järve's discussion Takeoff and Arm from GCS arducopter 2.9.1 in the group Learning to program the Ardupilot Mega"Is there a way to arm the copter and start the motors from the GCS? What I want to do is have a single takeoff button that I can press that arms the copter, starts the motors, and then takes off and flies the waypoints or just loiters…"
Nate Miller replied to Markus Järve's discussion Takeoff and Arm from GCS arducopter 2.9.1 in the group Learning to program the Ardupilot Mega"You can easily do it without any modifications to the existing code. Under the flight planner tab of mission planner, right click and select takeoff. Make certain it's your first command of a mission and that you only enter 'auto'…"

I would love to get your code or perhaps a more detailed explanation of how it works and what I need to do to get the ArduCopter to start the motors and takeoff from only commands from the GCS. I am able to build the ArduCopter and the…"
Sid replied to Markus Järve's discussion Takeoff and Arm from GCS arducopter 2.9.1 in the group Learning to program the Ardupilot Mega"Markus and Nate - I would like to have the ArduCopter takoff from the GCS too. I wasn't clear from the discussion what you changed in the GCS and what you changed in ArduCopter code? Can you explain it in more detail? "
Markus Järve commented on Alberto Casu's blog post ZuCopter - FullAuto Test #1 including copter flyaway - recovered :)"Very nice controlling while things were bad. This is why dev work needs to be done by one that knows how to fly manual. Love the way you recovered. "
"There have been a case of code isses with 2.9.1b.. check THIS thread.
Look near the end for details..

Markus Järve posted a discussionArducopter input ... I dont even know what.
Yesterday the quad-copter started to twitch. At first i guessed that one of the motors has to be going bad. After I looked at logs, I found out that input pwm is horribly amiss. The pich input is like shown in the log at attachment. It stops being like that only if I tilt the RC remote lever. BUT i was unable to detect this glitch on my rc receiver when using pulse time triggering on oscilloscope.Also the uploaded log was done when neither rc remote or quadcopter had any kind of vibration or…See More
Markus Järve replied to Benny Simonsen's discussion Crash during mission in the group ArduCopter User Group"It sounds a lot like something that I have had. (ok auto mission and then next one that just goes bats...) Thou I had no problem with baro reading. Just yaw change and "random crash mode initated!""
Markus Järve replied to Jay Butera's discussion How to calibrate ESCs without a radio in the group ArduCopter User Group"Do not do a first flight without RC control.
You can calibrate with mavlink but first flight without RC is rather dangerous and if you have little mis-configuration, your copter will fly away, flip, start a fire or just crash.
If you are…"
Markus Järve commented on ilana rothman's blog post Chris Anderson speaks at Serendipity about the future of personal drones"Yes, I understand the problem of safety. I was pointing out that mostly when doing any design, first priority is to get it working. It takes time. Especially for large project like this in what very few programmers are paid.
And sawmill…"
Markus Järve commented on ilana rothman's blog post Chris Anderson speaks at Serendipity about the future of personal drones"There will always be the 1%. Should the developer start with designing for the 1% or start with others and get to the 1% later? i see that sawmill example works still pretty nice."
