About Me:
Graduate student in aeronautical engineering. I focus mostly on rotor craft aerodynamics and controls.
Please tell us a bit about your UAV interest
I'm mostly interested in fault tolerance. Right now I'm looking into building an auto-rotation controller for a conventional helicopter. It'll be pretty cool if it works. Eventually I'll get into FPV flying. It's prohibitively expensive at the moment though.

"I put an APM 2.5 on a Bergen Observer EB about 2 years ago. The was powered by a gasoline engine. Whole project was a disaster. The heli shook so badly I couldn't ever find a way to mount the APM and get reliable attitude solutions. The helicopter…"
"Overriding the throttle input to make the copter ascend will work but is imprecise.
The autopilot can accept a set altitude command. I don't recall if it works in the current release or not. If it doesn't let me know and I can tell you how to fix…"

"2. Commands to arm / disarm motors
Use the command_long message to arm and disarm. I'll expand below in C syntax
command_long_send(target_system, //target_system is the ID of your mav.

"1. There isn't a command sent from mission planner to takeoff. It is an option when mission scripting (the script followed when in AUTO mode). Essentially, a takeoff is just a loiter command with the altitude slowly increased. If you want to take…"
"If it's 5 volts you can hook it up to UART 2 on the APM 2.5. Just write a little device driver to read from it. You don't need putty for the communication between the VN and APM.
If I had to guess, you're better bet for improving sensor performance…"

"Out of curiosity, what makes you want to use the VN over the onboard IMU?
I've had some luck getting a vicon system integrated where the camera system feeds attitude information to the autopilot. It was a bit of a mess getting it put together. If…"

"You can use the same code on the APM2.0 as you would on the uno"
"Yes, RTL (return to launch) works for traditional helicopters and multi-rotors.
One really cool features is that if you fly too far away and the autopilot looses contact with you the autopilot will automatically enter RTL and fly back to you. It's…"

I'm trying to get as much endurance out of my Y6 as possible. I was impressed by the Tiger Motor MN3506-16 motors mentioned on Forrest Franz's post here, so I shelled out for them. I'm using a 3c battery with the recommended APC 12x3.8 props which,…
"There's not really any good documentation on the different options when sending waypoints to your autopilot. Each autopilot, and even each vehicle type (rover, copter, plane) may or may not support a given mission command.
If you're looking for a…"

"We did our work on APM 2.0 - 2.5. Haven't gotten my hands on a 2.6 yet, but they're all nearly the same.
The Rotor Buzz comes with a really low quality autopilot. If you put an APM on it as far as I know that'll be the first."

"The Rotor Buzz II will meet your requirements, but it's around $100,000. I'd suggest modifying your project requirements. For something that big you'll need special FAA certifications that are right now extremely difficult to get.

"3D Robotics sells a little pito prob kit here. I don't think the arducopter software supports it but you can pretty easily pull the library in from the arduplane code.
