APM2 gyro/sensor not level

I have a problem with my APM2 where it thinks it's -5 degrees when it's level. I've measured absolutely everything to make sure it's not my floors, my quad, my construction, etc. Just to show how…Continue

So I've been following the quick start guide - I've connected one ESC with +, - and S while the 3 others only have S. The input rail is connected to my RX AR8000. When I power it by USB, all the…Continue
How to lower throttle µs?

I have an X650 Value V4 and the APM2 but I'm having trouble calibrating the ESCs as they won't arm. I read on another forum that the X650 ESCs run from 200 - 1000µs rather than 1000-2000µs. When I…Continue

Jessica DeVries replied to Geir R's discussion My motors always spin up and won't listen to radio on LiPo"Yeah, I figured out I had the same problem with my ESCs. Luckily my boss is purchasing new ESCs instead of having me figure out how to reprogram the old ones. What a relief! Thanks for your comments."
Geir R replied to Geir R's discussion My motors always spin up and won't listen to radio on LiPo"My problem was that I was using the Xaircraft X650 V4 and the ESCs it comes with. Those ESCs uses pulses from 0-1000us while virtually all the others use 1000-2000us as those the APM2 so I ended up buying new ESCs which was in the correct range and…"

"Yikes. Never heard of them. They may be incompatible, but perhaps someone who is familiar with them could comment. "

"What ESCa are you using?"
Jessica DeVries replied to Geir R's discussion My motors always spin up and won't listen to radio on LiPo"I am having the exact same problem and am stumped, so if you have figured out a solution or if anyone with more experience has some input I would really appreciate it! Thanks"
Geir R replied to Geir R's discussion APM2 gyro/sensor not level"I did do that the first time I fired it up, but I guess it wasn't level then and I had forgotten that there was a button for it so thanks for your help."
Vernon Barry replied to Geir R's discussion APM2 gyro/sensor not level"No, only when subject to extreme impact. A gyro has no concept of the horizon. The only thing it knows is change of angle from the point it started. Vibration and other fast motion can cause a gyro to drift (loss of accuracy over time since…"

Do gyros go bad often?"
Geir R posted a discussionAPM2 gyro/sensor not leveled
I have a problem with my APM2 where it thinks it's -5 degrees when it's level. I've measured absolutely everything to make sure it's not my floors, my quad, my construction, etc. Just to show how much it is, I tried to take this picture to show how bad it is. It's not easy to see it due to picture quality, but in the mission planner, it's almost level while you can see the bubble being all the way to the left. Is there anything wrong…See More

Geir R commented on Andreas M. Antonopoulos's group Telemetry over cellular IP"I'm planning on a similar setup but with an USB cam instead of GoPro. How did you get the Cotton Candy? I tried pre-ordering but haven't heard anything so I'm waiting until end of June for a Raspberry Pi."
Geir R replied to Geir R's discussion How to lower throttle µs?"I know, but I'm going for the cheaper solution here. :)"
