About Me:
I'm software developer, concentrating on mobile applications. I run own company named Lonely Cat Games, selling software worldwide on Internet to individual customers. In spare time I'm trying to fly planes, mainly feeding them with various electronics and let make them fly intelligently. This is my new hobby since 2007, and this makes me go out to fresh air more often.
Please tell us a bit about your UAV interest

"So far I fly with EM406, and results are bad. I can't even make plane follow fixed course.
Maybe that's because I want to use short distances (to see the plane and keep it in manual controll range), so distance from me is max 100 meters.
The problem…"

"Well, I now test code and flying on this board.
It has 6 channels input and 4 channels output, thus it can process anything with 4 channels (mix, pass-though, stabilization), while last 2 channels are for controlling fly modes (manual, stabilize,…"

"Andrew: that's perfect idea that should work!
I already know that Spektrum transmitter is by default configured to have throttle lever at bottom producing signal at ~10% of PWM range (1000ms ... 2000ms), and ESC treats it as no juice for motor. So…"

"jordi: another solution is to watch throttle signal, if it goes low, RC may be out of range. Then do something special like RTL. But one must consider this when manually controlling plane, manually gliding would not work then."
"This is from Spektrum AR 6100 manual:
SmartSafe
Your AR6100 features SmartSafe fail-safe programming. SmartSafe prevents accidental motor operation before the system connects and, in the unlikely event of signal loss, SmartSafe drives the throttle…"

"Jordi, will this work with 2.4GHz digital RC receivers? As I know, these RC's don't ever send invalid pulse, and in case of signal lost, my Spektrum RC keeps last values for all channels except throttle which is cut."
"Nice, but a bit bloated for our purpose. Mentioned 300 bytes is maybe data in memory, not counting the code size, which I suppose may be about 4KB. Too much if we have just 14Kb for whole code in AT168."
"Yes 5V, servos are powered with same wire, power coming from ESC."
"Primarily size, you see my polystyrene planes are rather frail for carrying too much. Also my other 1Kg plane doesn't have too much spare room, so anything smaller is better.
And I'm trying to use minimal hardware design, possibly proving that it…"

Here's a modification of original ArduPilot, running on Arduino Pro Mini.I'm just posting photos for now, since there's still lots of things to do for my planes to fly. Maybe when things are tuned, I'll post also modified code.My first testing or…
"When Spektrum RC loses signal, it keeps last values for all channels except throttle, which is cut down. Also autopilot toggle channel keeps last value (probably manual mode). This would result in plane crash.
Assuming Ardupilot can read all RC…"

"Will have to, because my GPS forgot stored settings after some days."
"Bryan: thanks for hint, I'll give it try and update the code."
"Best is if stabilization sensor would be a "plugin", replacable or selectable component of the software. Someone chooses IR because it works and is cheaper, someone uses gyro because of the valley or better performance. Stabilization code may work…"
"MattTay, you're the man!
That looks promising, but didn't you consider using IR sensors like is discussed everywhere on this site?"

"I fixed the ArduPilot_20090211.zip now, download it again. It contains those ArduPilot.vs folder, so just extract the zip somewhere. Then copy AVR Studio into that ArduPilot.vs folder.
Hope this helps."
