If someone recognizes the Pixhawk tone signal that you can hear 27 seconds into the flight, please tell me what the tones mean. The motors cut off right after the tone, and although the motors…Continue

Postion Hold not engaging..

I have been trying to reach someone who might know my problem by posting on my own discussion thread in "miscellaneous"   on my profile page. I haven't gotten very many suggestions or ideas, so maybe this is a better category.   (except for test flights, I am grounded)What can prevent the APU (Pixhawk) from entering Position Hold mode (3.2 and 3.2.1r1) when it has been set correctly in mission planner mode setup???  Before you ask my GPS status, I will tell you I only test or attempt to go into…See More

I cannot get the PIxhawk to execute position hold in 3.2 or in 3.2rc1I have this same problem on two copters, each using a different radio (TARANIS)and each has a Pixhawk, one on 3.2 stable version and one on 3.2rc1they both do the same thing.  I have a good enough GPS connection, in fact loiter works, here are some screen captures:…See More

"I found 1.3.16, removed 1.3.17, and installed the 1.3.16 It made no difference.  Position hold can be chosen under flight mode setup, and It doesn't work.  RTL works, and loiter  works they are GPS dependent but Position hold…"

"I don't think 1.3.17 is beta, It seems to be what I get when I go to the ArduPilot download site "latest version". I have been looking for 1.3.16 to see if it will correct the problem somehow. When discussing "position" I…"

"Are you using a Beta version of Mission Planner? The version I'm using is 1.3.16. I' not sure I understand your question, are you referring to stick position? Regards, Nathaniel ~KD2DEY"

Richard Evans replied to Richard Evans's discussion Why the motors cut off?
"Hi Nathaniel I have 1.3.17   I wonder if it could be a bug. I tried to find out where position is mapped to the PWM range, but couldn't find it. (my guess it isn't an easy parameter to find and set as layman like myself. Richard…"

"Richard, Just taking a really quick look at the log file, if you plot RCIN for CH3, throttle drops to 993 for about 3 seconds around the time you reach peak altitude for the flight. Your RC3_MIN is 992, RC3_MAX is 1997 so the FC is seeing low…"

Working on endurance options

Posted on January 18, 2014 at 6:30pm 21 Comments

I've been working on getting a better range and endurance. This QAV-540 weighs 5.5 lb's and I just flew it for 18 minutes today. Previously 16 minutes was my record, the change is that I went up one inch in prop size. This is not stripped down for endurance, I want something that will fly a long time…

Some FPV (Cockpit View)

Posted on December 13, 2013 at 3:00pm 4 Comments

!

This is just run of the mill FPV flying, but I enjoy reviewing the fight for more than the visual perspective. Re-living the altitude, the roll and pitch, the rate of ascent and decent, the airspeed during the flight and the battery condition gives me a much fuller context than just viewing the HD video I was recording using my GoPro H3 Black.  Here is simple flyover of ready to be developed…

I originally solicited other construction company users as to their ideas about using drones in the industry and to heat there experiences. This might not be the right venue for that, instead I got…

Near miss at the beach

Posted on July 23, 2013 at 3:00pm 9 Comments

This weekend I took a couple of boys to the beach (family members) and wanted to get some video of them trying to surf and using a boogie board, (in some very poor surf conditions). Something unexpected happened, through the  low resolution of the goggles, I mistook some other kid and hovered up close.  As he turned to face me, I realized he wasn't the kid I was expecting and instead of a surfboard, he had a surf casting reel. He cast his lure at my…
