"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…"

"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…"

"First, I wouldn't bother with Player since most if not all of the functionality has been replaced by ROS.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…"

"I would recommend the easystar (or skywalker) and then move up to a cheap fast if you need later (skyfun - funjet clone)."

"I've heard that the FunJet has more fuselage room and a lot of space for both UAV and FPV equipment. I'm likely to start such a project myself, so stick around for it :)But like Chris says, it's not for absolute beginners, you need…"

"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…"

"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. This paper was written by some of the team that is now at…"

"Supposedly you can fly at Flushing Meadows Corona Park in Queens http://www.nycgovparks.org/parks/fmcp/facilities/modelaircraftfields The flying field looks really small from google maps though. The other option in NYC is Floyd Bennet…"

"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. Now I just need to get the rest of the HITL setup working. [647] Read 34 bytes CMD:…"

"Agree on that. You need a common ground between all these elements. I'm not even sure why you're using ArduPilot for this. Why not use a regular Arduino board if you're not using the RC or GPS elements that make ArduPilot unique?"

"Are you using our code? (2.3). If so, as Tom points out it won't work without RC inputs."

"It's kind of hard to really know from the picture...it could be number of things...is the only connection between ArduPilot board and your GPS emulator board serial connection? If so, try having common ground between two boards and see if that…"

"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 board at the…"

"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…"
