"The Stabilize Control P seems to do something with it. I change the value from 4.5 to 0.45 and the motors slowed down, but they were still too fast. I lowered the value to 0.001 and the motors slowed down a little bit more, but it remains too fast…"

Magnetometer reversed. Points to opposite cardinal point

Hi. Does anybody know why my magnetometer points to the opposite direction? When I open the Mission Planner the OSD acts as if the front of the oilpan is the back. First, it points to the oposite…Continue

Nicolas Garza replied to Francois du Plessis's discussion Quadcopter throttling problem"Ok, for some reason the value of P in Angular Rate Control was at 0.185, even though the recommended rates are between 0.145 (for small motors) and 0.090 (for big motors) so at that value was way off boundaries, so I assume the system was thinking…"
Nicolas Garza replied to Francois du Plessis's discussion Quadcopter throttling problem"Haha, I was about to post the same thread as I have exactly the same problem, and almost your same setup (APM1.4 and DJI frame). I just reflashed my esc's with simonk's firmware and I thought that was the problem but it works normally if I…"
Nicolas Garza replied to Jean-Luc Combe's discussion XBee and APM 1.4 communication problem"btw, i just checked the voltage of the board and its around 4.7, is this normal? should it be a little higher? i don't think this is the problem, but I'm really not sure"
Nicolas Garza replied to Jean-Luc Combe's discussion XBee and APM 1.4 communication problem"Hi Jean-Luc.
I have your exact same problem, but with 900Mhz Xbees. The problems with Xbee's that I've had are related with the board (i have an xtream bee, and a red one from sparkfun).
First everything worked out of the box with the…"
Nicolas Garza replied to Andrew Laird's discussion Xbee 900 Kit - Lights, but No Telemetry"This is great. I had your exact same problem. And what was most frustrating is that i have like 3 sets of xbees, an xtream board and other sparkfun boards. I had telemetry for as long as i have had arducopter and ardupilot and suddenly telemetry in…"

Nicolas Garza replied to Nicolas Garza's discussion Magnetometer reversed. Points to opposite cardinal point"That's right. Haha I feel so stupid. I have been using this thing for like a month and have had no trouble with that, but then two days ago someone made a comment that messed with my understanding of the OSD, and that including the 180º…"
apocolipse replied to Nicolas Garza's discussion Magnetometer reversed. Points to opposite cardinal point"The roll axis isn't reversed, the behavior you describe is normal. If you hold your APM pins backward as should be, and tilt to the left, the line on the screen WILL tilt to the right. The lines on the screen aren't roll, they…"
Nicolas Garza replied to Nicolas Garza's discussion Magnetometer reversed. Points to opposite cardinal point"Solved it. Thanks for your input, but thankfully this was a user based mistake, and apretty dumb one. Turns out I put the magnetic declination with a point instead of a comma, so I had 553 instead of 5.53, so that's pretty much the 180 degrees…"

"Definitely loiter, waypoints etc will not work if your compass heading is that far off. Unlike a car or plane a quad/heli can move in any direction not just forwards so we can't rely on the GPS for heading info..so we need to rely on the…"
Michael Pursifull replied to Nicolas Garza's discussion Magnetometer reversed. Points to opposite cardinal point"I could not say if this is your problem, but I can related a similar experience. When I first updated to 2.0.40, I saw the same thing. I dug through the code to see if the default components-down-pins-forward define had changed. I moved the APM…"

Hi. Does anybody know why my magnetometer points to the opposite direction? When I open the Mission Planner the OSD acts as if the front of the oilpan is the back. First, it points to the oposite direction it should be displaying. If I am heading to the north, i says it's heading to the south. Then, If I tilt it to the left the OSD tilts right and viceversa. Although it's weird because pitch does point to the right directions. The magnetometer is directly soldered to the oilpan just like the…See More
