My copter does not respond to yaw input correctly, and while it does rotate it also drops an arm while its doing so.All of my props are correctly placed and setup, my engines are functioning, the…Continue

Fixed my pdb problem and everything, all the motors arm and run all right at the exception of motor 1.Motor 1 seems too be at least 20% slower than the other 3.I have re calibrated manually and…Continue

Sorry, I'm new here, please redirect me should there be a batter spot for this question.My PDB (from DIYdrones store), when powered by my battery and disconnected from apm, displays 12v out on all 4…Continue

"Ok so it looks like I've got even bigger problems at this point.  After takeoff I switched to auto mode to have the copter fly my simple 3 point waypoint course. After reaching the first waypoint the copter seemed to reduce the throttle…"

"Off the top of my head, you might have an arm/motor which is not straight, causing a yaw thrust. Or, what is your Thr_Min parameter?  I wonder if while you are trying to yaw, that your motors actually stop, so the arm drops until the…"

Yaw problem

My copter does not respond to yaw input correctly, and while it does rotate it also drops an arm while its doing so.All of my props are correctly placed and setup, my engines are functioning, the copter is stable.Any ideas as to why this might be happening?Thanks.See More

"Well things seem to be functioning fine now, I re uploaded the firmware ,reset level, and tuned my PIDS. The copter pulls slightly forward but only a tiny bit and I trimmed it out easily.  Yaw is no longer a problem really though the…"

Sakar Mortalatis replied to Andy Theimer's discussion 3DR Quad First Tethered Flight - Flies right + forward w/o radio input.
"Well I just got back and I must say overall this was not an enjoyable experience. Firstly the copter seems very unstable, and skitters all over the place. This seems to get worse with time too, though really I blame my PID's which are…"

"Hey as I'm having a very similar problem what exactly did you do to fix this issue?"

Sakar Mortalatis replied to Sakar Mortalatis's discussion Really......
"I can confirm that the APM is realizing the quad is not stabilized, though it doesn't look like its making any effort to correct itself. at 0-40% throttle the quad drops motor one by 15 - 30 degrees at 41-60%…"

Fixed my pdb problem and everything, all the motors arm and run all right at the exception of motor 1.Motor 1 seems too be at least 20% slower than the other 3.I have re calibrated manually and automatically 3 or 4 times. This is absurd.See More

"The real moral to this issue is not use knock-off Deans connectors. They are sold all over the internet. I have never had a defective "real" Deans power connector. Just a thought. Regards, TCIII"

"The fucking deans. Turns out the deans plugs where somehow broken so that they had perfect connectivity at the ends, but absolutely nothing on the actual terminal pieces for motor connectivity. "

"Ok an update, this is very strange. I am getting 12v out on all four of my connections, yet on the motor one and two slots any of the four esc's do not seem to get power. I have confirmed that the "ticking" is the result of the…"
