autopilot theory?
Any good introductory material on autopilots, flight control, etc? Not necessary to be UAV-centric, traditional aviation resources would be welcome as well.

MediaTek GPS not responding with APM
Hey All,
I recently purchased the MediaTek GPS, from the DIYDrones store, for my APM board and so far have not been able to get it to respond (as in it will get gps lock but the C light on the oilpan does not light). I am running the APM 1.01 code. I

Now that lots of people are getting their Arducopters in the air, and that position hold is implemented and stable; I'd like to discuss GPS Position Hold Accuracy.
My GPS Hold works as advertised, it stays in a 3-5 meter area and the altitude typical

Hi!
If i´d like to use QGroundControl, I think I have to compile a other Software for the APM (The mavlink - one) am I right?
If yes, is it developed as fast as the original. Is it possible, there are bugs inside, you removed in the 1.01 Version (Alti

Does anyone know of a relatively ready-to-use solution for sending serial data over an existing SD video stream? Maybe during the vblank section of each frame?
I'm hoping there might be an existing solution that would let me stream in serial data, e

Hi there
I have a EB-85 gps connected to an Arduino
I used TinyGPS from http://arduiniana.org/libraries/tinygps/ and
was able to obtain NMEA sentences from my GPS
and also display then on the serial monitor of the Arduino IDE
I then modified the code by

Hi!
Can anyone tell me, whats new in the Version 1.01? I cant find a changelog anywhere.
Is this a flyable Version?
Thanks

The connector for the GPS cable was torn off my IMU in a crash. Are all of the connections for the GPS available somewhere on the header slots so I can rewire? I can get continuity on all but one but on that one the solder pad was torn off and I'm no

Hey guys, for the life of me, I can't seem to get the configurator to update the PID values.
The configurator just hangs and freezes when I attempt to update. Both the copter and configurator are in stable mode, and as far as I know, there are no hard

I've spent a few flights trying out the "GPS Hold" feature on the Arducopter, and have some questions.
(This is the FahPah kit, with the MTK GPS and untouched RC2 software.)
The ship is rock-solid in Stable mode. No problems; like the most docile hel

Anyone able to explain this line from Advanced Configuration Settings?
"Adjust AIRSPEED_RATIO in small
increments to calibrate the airspeed sensor relative to your GPS."
I would like to better understand the relationship between

Hi all,
As I experiment a little more with APM in my Skyfun, I wonder if there's a suite of attributes we could use to compare airframes and get a good idea of where one airframe performs better over another. Just for starters, example attributes cou

Like the title says, I'm wondering if anyone as a ready-to-fly quadrocopter that they are willing to sell for a decent price. What I mean by ready-to-fly is that it has working/calibrated motors/ESCs. Having it work with the ArduCopter boards is a pl

Okay, so I'm trying to place my XY thermopile on a delta wing but have issues because of the vertical stabilizers. I don't get a clear view about 15-20 degrees off center of the two rear sensors towards the middle of the plane. Is this going to be a

First off, A big thanks to all of the people who have worked so hard to lower the technical difficulties of getting into Quadcopters. I'm a technical person but this is my first dive into RC aircraft.

I am hooking up a couple of additional digital lines to AN4 and AN5 as labeled on the IMU. How do I reference them as digital pins from within the code? For example...pinMode(???,OUTPUT);...digitalWrite(???,HIGH);...digitalWrite(???,LOW);What is ???T

I am looking for some documentation about input/output assignments on the ardupilot.
For example, it boasts 16 ADCs and from the code it looks like the three gyros are on channels 0, 1, & 2 and the three accels are on channels 3, 4, & 5.
Is there som
