"Hi THomas, yes I use this method when level is only slightly off. But when it's completely screwd I just can't bring quad up into the air. And this is what usually happens after cold landing. "
"I fly in up to -15C in Russia with Hobbywing ESCs and it's going OK. But I have another problem with cold on my APM 2.5 quadcopter. As soon as it goes below +5C leveling gets completely screwd-up upon each landing. Soft landing into snow or hard…"
When I started using my APM2-based quad in sub-zero temperature (actually around +10C still) I have to re-level it almost after each landing, even the very soft landing. Maybe it's not the temperature, but I have to check something else?
I used this FTDI-USB antenna on old Windows XP unit and it worked well with MissionPlanner etc. However after switching to Windows 7 it gives bluescreen almost every time I remove my antenna from USB port. It seems to be using standard FTDI driver…
"It seems nobody interested/tried using this feature. Weird, it seems to be useful for all kinds of external devices. Anyway the problem is that there is no initialization of channels 5-8 in the ArduCopter code. Looking at init_rc_out() there are…"
"In my case jitter behaviour of MTK doesn't depend on firmware version and mode. I've done clean experiment just walking around with armed quad and then analysed log files (2.6 and 2.7.1). I see ~3.5 Hz "stairs" in raw GPS readings. It's probably…"
I am trying DO_SET_SERVO in MavLink. It seems no signal on the output channel gets generated. I am attaching mission plan and graph of two successive missions. For the comparison I graph servo1 (motor) and servo5 (the one I am testing). servo5 stays…

"So finally how the Home Location is set??? Since I had bad crash related to lack of this knowledge I looked inside the APM (ArduCopter 2.7) code. Just want to warn that ArduPlane code may have different logic. Here is the logic:
"Hi John,
I have similar problem and try investigating it. Found this line in Log.pde
DataFlash.WriteInt(0); // 7 (this used to be compass.heading)
So by some reason 2.7 won't log Mag Heading anymore. Wondering why.
But the reason for erratic…"
Both in Mission Planner (1.2.5) and in Google Earth (6.2.2.X) when playing tlog - kmz files there are no waypoints, just the trajectory. Is there way to get both trajectory and waypoints on one screen?
Hello,I use APM 2.0 with 2.7 firmware. I noticed that log erase works strangely. In fact it doesn't work. I erased all files from CLI. Then powered on, armed and switched off after couple of seconds. Then downloaded new log file. It appeared 3+ Mb…
"Hi Dan, I use 1.34, works great! Just one minor issue probably related to my regional settings. When clicking on trajectory area, the coordinates passed to Goggle Maps are with decimal commas, while should be with decimal dots.They are passed…"
On the Wiki page for Auto mode there is description of what should happen when Mission completes in air. It should switch to Loiter.However in my experience, upon completing mission, copter will switch to Stabilize mode and follow the throttle. If…
Hello,According with definition of MAV_CMD_NAV_WAYPOINT the second parameter is the Acceptance radius in meters (if the sphere with this radius is hit, the waypoint counts as reached).When I set WPRadius on flight-planner screen to 10, and save…
