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 replied to Barry Nash's discussion Altitude hold drops slowly then shoots up full throttle
"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...  "

Arducopter 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 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…"
