"Ralph, don't get discouraged, large chunks of the necessary code are already working and I'd be happy to help answer questions you might have. Though email is easier for me.
Most of what needs to be done is figuring out how all the parts fit…"

"I'm pretty busy at the moment so I am not sure how much code I can contribute. Also, I don't currently have an APM and I don't know what state the MAVLink interface is at. The APM MAVLink interface should be able to use most of the same messages to…"
"First, I wouldn't bother with Player since most if not all of the functionality has been replaced by ROS.
Second, I would suggest working on improving the MAVLink interface to connect the data to ROS. This provides a common interface for the various…"

"Duane,
Do you have references for the AMA's legal attacks on alternative organizations?
Why not try to use something like kickstarter to get enough funds together to start an alternative to the AMA that has sufficient funds to deal with lawsuits…"

"I have had nothing but problems with acrylic parts cracking on things I've designed. It might be worth trying wood or ABS."
"Excellent work."
"They are using something called relay tuning for their controller design, which looks like an automated version of the Ziegler Nichols method.

"Supposedly you can fly at Flushing Meadows Corona Park in Queens

The flying field looks really small from google maps though.
The other option in NYC is Floyd Bennet Field…"

"Thanks for all the help, it looks like it was the RC inputs bouncing around. It has been working flawlessly once the receiver was plugged in.

"There is no GPS connected since I am trying to debug a GPS emulator.
It's almost working but I'm having a problem with my checksums matching and the serial port acting up is driving me crazy trying all day to debug it.

"The protoboard has a +5v switching regulated power supply.
The power is connected through the power and ground of the servo connector but I am having similar problems when connected next to the ftdi cable. but it seems to work a little better.
So I…"

After fighting with this for the last few hours, I'm going to ask for some ideas.Right now I am having really bad serial communications problems, often the board just randomly hangs and does nothing. It seems like there is some sort of…

The AIAA paper on the relay tuning it uses for adaptive control looks pretty interesting.
I have a copy somewhere but have not had time to read it thoroughly."

"Ok today I am looking at the servo PWM subsystem...
This afternoon I got the connectors soldered to the ArduPilot and hooked up a scope and it looks like the way the PWM signals are generated is interesting. I went through the source and it looks…"

"In general brushless motor controllers are a little weird.
I had a lot of problems with startup on the some of the castle creation brushless ESCs, however they worked a lot better after a firmware update. The techsupport from castle creations was…"

"The secret to getting this working the easy way is you need PPM compatible PWM signaling.
If you use a decade counter to generate your pwm signal, (like almost every R/C receiver) then you just OR the outputs together with diodes then use one i/o…"
