"The 99.9999999% are really hard to believe - especially when considering the X8 layout.
I have learned from several crashes that the X8 layout does not provide a lot of an reliability advantage over the usual quad, if any. One example: one of the…"

"@Tom: I do not aggree - the single point of is very easy to avoid: simply move the switching logic into the ESCs. Some problems might persist (which FC is right?), but at least you have 6..8 redundant switches and a redundant wiring.
BTW, given that…"

"As far as I understand the device, the AP Manager itself is can be considered as a single point of failure. It adds another PCB, plus lots of additional cables, all of them can fail. So where is the improvement in redundancy or reliability?"
"NAB show seems to be over - any news/details/facts on the UMC-R10C so far?"
"I have flown the v2 module with ArduCopter (master) an can confirm that the new module is working nicely and performs very well. It is almost plug-and-play with APM: after setting the params BRD_CAN_ENABLE to 2 and GPS_TYPE to 9, it is auto-detected…"
"When losing one motor on the X8, shouldn't it be enough to throttle down exactly one opposite motor? That means we have lost 2/8 (25%) of power, not 50%. But probably we need the ESC feedback here to find out what motor has failed.
Overpowering the…"

"After some years of experience with ArduCopter, I would characterize the reliability aspect of ArduCopter as good, while the functionality aspect is outstanding (IMHO).
When looking at my past crashes caused by ArduPilot (about 10 or so in about…"

"Hi Sam,
amazing work! Have you ever tried to commit your work to the upstream OpenTX project? That way your changes would be maintained by the upstream project and your changes would "stay alive" in newer revisions of OpenTX without having to adjust…"

"Hi Justin,
inspired by your post I just browsed some old logs. I found two logs of flights at approximately 1C. All measurements were taken with calibrated SM Unilog current/voltage sensors. Both flights were in Februrary at 14°C, and 16°C…"

"Any ideas? Is there anybody who has experienced the same limits or climb/descend rates larger than 5.45m/s?"
Just tried an high-altitude mission, controlled by two waypoints in AUTO mode. Surprisingly, the copter did not climb as configured by WPNAV_SPEED_UP/DN. (set to 1000 each).Instead, the logs show a remarkably flat line at 545 cm/sec on both legs,…
Just did some flight testing in windy weather. After some THR_ACCEL tuning, the copter is quite stable, even under these conditions. Finally tried a loiter in 75m AGL. Wind speed seems to be arround 40 km/h today in this altitude, but the copter…
"Normally, I am using MavProxy instead of MP, but may be it has interferred and silently reconfigured my APM when it was connected once...
Thanks,

Due to some regulatory issues I am trying to reduce some telemetry stream data rates using the SR3_* parameters. I would even like to disable some steams completely. Unfortunately, there must be some hard-coded minimum limit per parameter in the…
"The APM with the Init Gyro problem was not involved in any crashes - it was brand new. I returned it a week ago, waiting for replacement now."
Hi,in summer I was running an APM 2.5 quite successfully. Unfortunately one day I hit the ground with 100 mph, and the only surviving part was the damn motor :-|I just bought a new APM, but it seems I am still out of luck: after successfully…
