I'm not really sure if this is an issue or not or even where to find it if it is. So when I power up the APM 2.5 with sw load 2.74b, after the initial power-on test the aileron servos would lock up for about 2-3 seconds when I do rapid movements. It'

Weird problem with the logging everything else works, logging problem is:
the cli will not respond unless I have a separate power to the APM with the usb cable power as well.
when cli responds I go to log download and it starts then just hang

I need help analyzing my logs and need to confirm if the crash in auto mode was caused by an elevator servo problem or an airspeed problem. This was flown in a remote region far from people and property.
5 minutes into the flight, the aircraft

some times ublox modules when cold start
reports "3D fix" with high error - with hdop = 4.0
this mean accuracy +/-1km around real point.
before each fly with ublox module i check home position and reset APM when it incorrect.

Recently I managed to tune my APM installed in Multiplex Fun Cub. Since it flies quite well I'd like to share my param file with you - please find attached. My setup:
Hi guys,
I was wondering if anyone here has tried to use APM datalogs with Pix4D? I am currently using a cropcam to do mapping but I am looking at utilizing the APM logs to do geo-referenced maps without the use of ground control points (because the f

I completed quite long flight today which confirmed what I noticed while ago: when flying straight towards waypoint APM keeps plane rolled by ~7degrees. Initially I thought that root cause might be wind, but todays mission was rectangular a

I am trying to artificially give airspeed voltage to APM AI0 pin using a Digital to Analog converter. The digital values are coming from JSBsim and are converted to voltage in DAC(0 to 2 volts) which is connected to AI 0 pin on APM 2.5.
When I use

I’m playing with TECS controller right now and found fine tuning to be difficult. Main reason for it is lack of documentation for this control loop. I’m wondering if Paul or someone here could post block diagram as it was done for roll pitch an
I'm using APM1.4 hardware with ArduPlane V2.74b firmware and a Spektrum R/C system.
When I switch between manual & stabilize modes the throttle output changes.
If throttle is at minimum in manual [ 1089 micro seconds ] , switching to stabilize causes
I would like to study current vs speed of my Skywalker as Andrew Tridgell did in his Tuning the Techpod blog. It sounds like he just put it in circle mode (a large radius I assume) and manually increased speed over a period of 20 mins.

Could I please get a second opinion on a set of logs? If I'm wrong, and this is something I could have prevented, I would like to know that before I fly again.
This weekend I suffered my first crash which I can be certain was caused by the APM. As y
