This is all a bunch of speculation that is pretty much completely untrue. I have seen it many times before. Most people who think that multi-rotors are inherently more stable than helicopters, only believe so because they have never flown an electronically stabilized helicopter. And I don't...

Only when you consider that that system only works indoors. I find those videos interesting, but until they figure out how to get that performance outdoors, the applications are very limited. It's just a novelty really.

Jello? I had a second look... don't really see any jello. There's a bit of shake in a few places though. The only place I saw Jello was what appears to be a zoomed in shot of the flare. But considering they are using zoom... doesn't seem so bad? Am I missing anywhere else?

This past weekend in Colorado, Sparkfun hosted an Autonomous Vehicle Competition. Arducopter controlled quads completely dominated the event, sweeping the top 5 positions. I did some runs with my Arducopter 450 heli, but was not competitive against the quads. Basically, the event required a...

Yes, that is correct. Randy has been working on the code development full-time (and probably more) for about a year now. And not coincidentally, that's when things really turned around. It is no longer a free-for-all, and the stability of the code now reflects that. However, strength builds...

Ok, now I understand. What you're talking about is rate control. APM can do that, but it's not the primary use so it's weak. Warthox wouldn't like it. I'd rate that a 3, but A/L is a 4 or 5. I'm working to make it better though. I'd love to get a quick sketch of how HF tuning works.

Which code did you fly? Our attitude system didn't get really good until 2.8, which was last fall sometime. But still, tuning of PID's is, and probably always will be required. I actually can't conceive of how it's possible to not tune PID's on any system, unless the performance of the system...

Interesting work. You have missed AutoQuad. It's not as well known, but seems to perform quite well and is Open Source. I think SOD of 3 for APM is a bit low. 4 is more appropriate, IMO. Obviously this is somewhat subjective. But we have users flying quads without touching a single tuning...
