I recently purchase an APM 2.6 with external compass and GPS.  I programmed a simple route that is very short in distance - just rotates around my ground position twice using about 9 way points.  On…Continue

"I've run my batteries as far down as 11.1v (3.7/cell), and the OSD still works fine.  I don't think there will be a problem with 10.5, but I'm not sure since I don't run my batteries down that far. "

Fishtailing / Wobbling in Auto mode and Circle mode

I recently purchase an APM 2.6 with external compass and GPS.  I programmed a simple route that is very short in distance - just rotates around my ground position twice using about 9 way points.  On the ground, stabilize mode works correctly as I rotate the plane around.  Switch back to manual take off and everything is fine.  When I switch to auto mode, I can hear the motor speed vary and the plane wobbles through the air as though the ailerons are fluttering.   I uploaded the log file to:…See More

Help - FatShark 600TVL CMOS camera - MinimOSD problem

Anyone had a problem with this camera, where the video signal comes through without the digital overlay?  But then when I jiggle the camera - I have no video signal but I CAN see the digital readout of the OSD.  Problem is I can't get both the digital overlay and the video signal at the same time.  Please respond if you have had this problem or you have an idea on how to fix it.   Thanks in advance for your help.The camera has 3 pin connections video, ground and 5v pwr.  The video  V/Tx is…See More

Another article about peaceful use of drone technology in the NY Times

Posted on March 19, 2013 at 12:53pm 3 Comments

Seems as though the ratio of articles about peaceful, productive use of UAS technology to fearful, war themed, police state articles is running about 1 to 10.   This one takes the time to interview people that have ideas about using them for good purposes.…

99 cent Ublox Container

Posted on December 26, 2012 at 11:06pm 3 Comments

Found a neat little plastic box at "The Container Store" for 99 cents.  Fits the UBlox LEA 6H in width and height perfectly.  May need to stuff a foam spacer on the length wise side.  Just tried it in the backyard and the GPS got a fix in about 30 seconds - the plastic cover is not adversely affecting the…

Finally Got the maiden flight of APM 2.5+ done

Posted on December 24, 2012 at 4:30pm 6 Comments

I waited until I was able to get the Bixler Chassis installed before I went out on a flight with my APM 2.5+.  Once I turned it on, the uBlox got position really fast.  It was really windy today.  I took off in manual mode, flipped the switch to "Stabilize" and it leveled off like a champ.   I alternated between Manual and Stabilize for a while, then I switched to RTL and it performed perfectly!  Really glad I got the Chassis, because it made attaining the CG super simple. …
