"
sonar is accurate to within a few cm while the barometer is only accurate to within a few feet. I would suggest getting a sonar but that may not be the actual problem."

when executing the land command my quad descends ok but once it hits the ground it hops back up instead of stopping. I noticed in the CLA that the sonar gives false readings when its on the gound and…Continue

Greetings, Yesterday I preformed my first successfully autonomous flight with my quad. Take off and loiter worked well (loiter alot more so then take off) however once it came to RTL and Land the quad seemed to rebel. Now it seemed like the quad was actually "learning"... every time I told it to loiter or rand the mission script ( take off, loiter, rtl, land) it did better ( first take off it shot straight up way past the 5m but second time it held the 5 m) but RTL and Land never got executed.…See More
Jeff Cartwright replied to Gareth Rens's discussion First Auto-Take Off and loiter video"I did kinda noticed that.. the first attempt she shot straight up and I though it would never come down... the second she actually stopped at the desired altitude yet kinda wondered away..."
Jeff Cartwright replied to Gareth Rens's discussion First Auto-Take Off and loiter video"Hey, I tried to do the same basic thing and it seemed to take off and loiter for a second but then when it should have RTL and land it just seemed to go off into the field. I was wondering if you had figured out any thing yet?

"Sounds like you've either created a short when you soldered on the mag, or have the GPS plugged into the wrong port."

Hey guys I had the apm acting as a stabalizer with out the magnetometer or gps connected and it flew wonderfully. I just received the magnetometer and gps in the mail and connected them as per the manual.. I then reset the apm using the apm setup. however nothing is working every other time I will get a "set sysid_sw_mrev failed" error. I cant configure the radio, or even level the quad... Help?See More
Jeff Cartwright replied to Jeff Cartwright's discussion cant disarm motors and quad always yaws right?"I'm not sure what was causing it put i ran the radio test and played with the end points untill i got -4500 and 4500 (ended up being at the exact same points I started with? )
now I can arm and disarm..."
3D RoboticsChris Anderson replied to Jeff Cartwright's discussion cant disarm motors and quad always yaws right?
"Jeff: those are indeed very funky values. Most transmitters will output ~1000 to ~2000. Do you have your in some weird mode? It shouldn't be in any heli mode, and you can turn expo off. Obviously you don't want any mixing,…"
Jeff Cartwright replied to Jeff Cartwright's discussion cant disarm motors and quad always yaws right?"ok I got 4263 to 14684?- its my transmitter then?
however when I'm calibrating it it gos from
1333 to 1697"
u4eake replied to Jeff Cartwright's discussion cant disarm motors and quad always yaws right?"Connect to the apm in cli mode.
go to test, then type radio.
Numbers should start flowing.
Move yaw stick all the way from left to right and back.
The number in the 4th column should change from -4500 to 4500. If it doesn't your radio is…"
