I've run the compass calibration and I will run the compassmot next using the CLI.
Is there a written guide that documents the steps for the compassmot to ensure I do it correctly.

Fun Wey posted a discussioncalibrated parameters in Arducopter
Hi;I am going to include customized usercode in the arducopter sourcecode, and thus cannot use APM to directly upload the compiled code from internet into the board. I intend to calibrate (RC channels' upp and low values, trimmed data, etc) uisng the APM first. I can manually record down these calibrated parameters but need to know the corresponding locations of these in the sourcecode so I can then input the values in the code. Are they all stored in the config.h file ? Where exactly…See More

Welcome to DIY Drones!
This is the home for everything about amateur Unmanned Aerial Vehicles (UAVs). Use the tabs and drop-down menus above to navigate the site. (About us/Site rules)
This community created the Arduino-based ArduPilot, the world's first universal autopilot (planes, multicopters of all sorts and ground rovers). The APM 2.5 autopilot hardware runs a variety of powerful free UAV software systems, including:
- ArduPlane, a pro-level UAV system for planes of all types
- ArduCopter, a fully-autonomous multicopter and heli UAV system
- ArduRover, a fully-autonomous ground-based vehicle system
I'm new to all this--where do I start? Are amateur UAVs legal? (yes)

How to succeed without really trying

My quad is flying better than it should. I almost feel guilty.
I slapped together a frame in a few hours. I use cheap props mounted on long shafts with cheap collets. The motors are not precisely aligned to the frame. The props are not balanced perfectly. Motor centers form a rectangle not a square. APM is strapped to the frame. I never bothered to calibrate compassmot. CG is not in the center of the…

Novel application of 3D printing could enable the development of miniaturized medical implants, compact electronics, tiny robots, and more. It will probably take a while before this will be used for the hobby markt, but I though the story is nice enough to blog about it.

In this post I’ll describe how to make your own cable to trigger the Samsung mirrorless cameras NX20, NX210 and NX1000. We’ll be using an ArduPilot Mega 2.5 to do the triggering but you can use any Arduino or even a soldered push button.
