Slow upwind and fast downwind making loiters oval. What to tune ?
I am flying on a 3 channel Bixler (no ailerons) as I want to open a plane drone school and 3 channels systems are so simple it could be flown by 10 years old kids within 2 days, especially if I limit the maximum roll.
When wind is over 5m/s, my Bixler

Ublox 3DR
No more GPS fix, bad GPS health on MP, compass working OK.
Power on Ublox says 4,87v when connected to USB and 4,95v when connected to Lipo
I have the jumper off and a 5V bec on the outputs, everything worked fine until now.
I suspect some cabl

I am trying to figure out how to get my plane tuned for level flight and climbing. I have a Bixler 1.1 that is set up for long duration flights. It weighs ~1100 g and makes ~425 g thrust. I want to set 11 m/s the default airspeed in flight (I have an

All missions now go very well, except I have to make a few trials before correctly reaching waypoint #1 for each mission.
Is there anything special to know or to do between Home and Waypoint 1 ?

Greetings from Cannes, South of France.
May I suggest a new APM mode : "twister" ?
Now that we are entering the 3D world (video, printers, scanners), I can foresee many uses for that mode. Photogrammetry, inspection, even selfies... Could be used by p

Before doing that, I would like to have your opinion.
I have always tried as much as I can to take advantage of nature forces instead of fighting it.
So I am starting from a fact : upwind flights are way slower than flying downwind.
I want to take advan

Hi,
I am flying my Bixler in stabilize mode and auto, everything works fine including RTL (I have to wait 5 good minutes after first GPS fix for proper home than it is ok).
I have just overloaded my Bixler with a Canon A2500 and a Mobius on the wings
Read more…First mission : plane keeps on climbing between waypoints and never stops...
First mission on a bixler + APM, I am ALMOST happy.
Problem : plane climbs above the pre-determined waypoints while doing the mission and keeps on climbing. I have no clue why.
It should have nothing to do with cruise speed right ?
Is my barometer not w

Hello guys,
About to do my first RTL tomorrow.
Is there any throttle variable to input as in a copter, or is the throttle managed entirely by my TX ?
Thank you

I am using the APM on an hexa without problems.
I am now building a Bixler.
I have 4 servos (2 ailerons, 1 rudder, 1 pitch) connected to three cables to the APM outputs and 1 ESC opto also connected to the APM output.
I therefore need an external source

Sorry, Let me make it more clear, in case of some long distance flight, I need two safety pilots, one in takeoff point with a RC controller to be able to make manual mode control, make sure take off safety and be sure that plane goes normally. Anothe

I am trying to tune my speed for different parts of a mission, but when I use the DO CHANGE SPEED command, the APM goes haywire as soon as I hit the switch from manual mode. I am trying to use it at a couple different places in the mission.

I know that most people here would manually take off, than loiter, than start mission.
A swiss company has been intensively using a system which allows the engine to start at a ready-to-mission speed when shaked. Basically, when you are ready in the f

Can I keep my telemetry and GPS/Compass from 3DR I use on my APM for the Pixhawk ?
Are the cable connections exacly the same ?
Thank you.
