Hi guys,(Posted this as a reply in another thread but I wanted to ask specifically about the compass)Last week I had a really scary crash, my quad was running in autopilot and suddenly decided to take it's own route. Within seconds and before I…
"This looks familiar, although in my case my quad was running in autopilot and suddenly decided to take it's own route. Within seconds and before I could react, it was completely off course and out of line of site.
As a last resort I activated the…"

"Just to clarify, where exactly is earth on the APM2 board? Just any negative pin or is there a particular place to earth it?"
"Hi guys, so here's a look at the difference between before and after power filtering of my MB1200.
It looks cleaner, but I'm still getting these very sharp downwards spikes which I think are causing my quad to twitch while in Alt Hold mode. I am…"

"Kur: I bought them from my local hardware shop. Where I come from it makes no sense to order a resistor and cap online.. :)
Randy: Large cap and resistor installed, initial bench testing show sonar works fine. Will need to fly to know if I can get…"

"Thanks Randy,
I finally managed to get my hands on a resistor and a capacitor similar to the one that you have. I'll report back on the results. I already use a shielded cable and ferrite cores on the 433mhz 3DR radio and 5.8ghz video TX."

"Randy that "before" graph looks exactly like my sonar graph now! The bottom graph was a result of the power filtering or cable (or both)?"
"I've been pulling my hair out trying to get my MB1200 to work as it should.
So far I've added a shielded cable, ferrite cores on both my 3DR radio and 5.8ghz video transmitter. (The ferrite cores did the most noticeable change for me.) I've yet to…"

"Update:
ESCs are fine, it seems that the new motors just needed some "burning in" to match the old ones...
Thanks!Ervine"

"I finally got a change to fly on auto today, I was super excited when it seems to fly in a near perfect line from point to point with very slight stops, but when it reached the 2nd last point, it stopped, loitered and started to auto land. It was…"
"I just wanted to drop a note saying that the new 2.7.3 firmware flys wonderfully!
I'm flying a DJI 450 stock (frame, motors, esc, props) and was using the default PIDs but I changed Stabalise P to 1.45. Stabalise mode is super duper steady, in fact…"

"So sorry to hear about your crash, but good to know what no one was injured!
I was looking at the logs with Dan's log visualizer and your video at the same time to see if I could spot what went wrong.
I'm pretty new at looking at logs (after my…"

"I flew 4 batteries yesterday with a mixture of Auto and Manual modes, did 4 different missions repeatedly at different altitudes and couldn't replicate the problem I encountered previously.
Tried with sonar and without, with onboard video and…"

"I just realised I used to be able to download logs even with 2.7.1. I am not sure what changed since then but no matter what I do (remove and reinsert, electrical tape thickness thing, erase and reset) CLI says no data flash.
I really hope its a…"

"I wish I saw this post a few weeks ago when I was pulling my hair out thinking what I did wrongly.
Yes the DJI ESCs do not have an inbuilt BEC, I am now running a Castle BEC programmed to output 5.3V (as suggested by the wiki page with the jumper…"
