"I am having a similar issue with the both my Quad and Hex (APM2.5 with latest firmware) As soon as I apply any Yaw it will lose altitude. Did you fix the issue? If so How? Sonar only works with Alt Hold and loiter as far as I know.. (I have sonar…"

Bart Mowrey replied to Nati's discussion APM 2.5, Motor setup: only one motor is working.
"Hi Nati- Ive seen that problem more than once, and never got a satisfactory answer here. From what i could tell it boiled down to a few things: 1. check all of your bullet's solder joints. You can test across the joint with a resistance…"

"For safety, we no longer allow software reversing in ArduCopter, since it can lead to unpredictable results in some modes. Instead, you should reverse channels at your RC Transmitter side. "

zmooth replied to Bart Mowrey's discussion What conditions cause ESCs to lose calibrations?
"Yeap, that's the one. Besides externally oscillated, it's also N-FET instead of P/N-FET which is usually more efficient especially at partial loads (most of the time in multicopters). And has programming pads for easy flashing."

zmooth replied to Bart Mowrey's discussion What conditions cause ESCs to lose calibrations?
"I personally couldn't calibrate internally oscillated ESCs properly; they would drift after some time (mostly tested on HK-SS20A-HW which run the same tgy.hex as yours). I had to re-calibrate before every flight, doing so out in the cold helped…"

Bart Mowrey replied to Bart Mowrey's discussion What conditions cause ESCs to lose calibrations?
"Ill amend that with RC Timer 18/20A ESCs flashed with TGY.hex with, according to the ultra helpful chart link, an internal oscillator. The original question stands, though, as to what, in fact can cause de-calibration. I should elaborate i suppose…"

zmooth replied to Bart Mowrey's discussion What conditions cause ESCs to lose calibrations?
"Check if your ESCs have external oscillator (ESC specs). You want ESCs with external oscillator , the Atmel's internal oscillator is not accurate enough to sync several boards together and its frequency will vary with temp. Internal…"

R. D. Starwalt replied to Bart Mowrey's discussion What conditions cause ESCs to lose calibrations?
"Bart, The short answer is 'No. Everyone does not recal ESC before a flight.' The usual problem is making sure you have good cal to begin with. Are you familiar with the CLI mode in MP (mission planner)? I ask because there are several…"

What conditions cause ESCs to lose calibrations?

or, in what case does the ESC lose its calibrations or de- sync?The problem is this:  my Hex's ESCs have simonk firmware, and don't seem to hold calibration for very long. Granted I'm not an expert here and haven't yet flown a great many hours with this copter, but something has caused calibration to be lost in one or more ESCs over time, several times. ALL-at-once re-calibrations NEVER have worked reliably, necessitating calibrating them separately.I guess i want to know if this is a process…See More
