Latest report from the front: (My) translation into English - the core team are (as always) doing a thorough, professional job on this, not just "hacking the code to make it work" - we can expect a super-flexible system that supports many permutations. We just have to be patient :cool:

Problem is I don't think we should be asking the core team to devote any time to this right now - they've got more than enough on their plates. Have you tried flying a quad with the CC? I'm guessing it would help to become more familiar with the tuning parameters. In basic terms I think the...

It's certainly possible (with a second, separate Tx/Rx) but, like I said earlier - stabilisation settings need to be tuned to the application. I'd be interested to hear what problems Pano-Dirk encountered. Nobody in the core team has tried this yet - they've simply pronounced it "possible"...

Programmers? No! Anything but...! I've seen their code - it's a mess! In the bad old days when I ran programmers, I'd have fired anyone that turned in code like that!

Probably September - customs delays, manufacturing delays, etc. - not Dave's fault, just unlucky

A "shrouded propeller" is quite a different matter to a "ducted fan". Well designed, I agree with Denny that a shrouded propeller could gain enough efficiency to compensate for its extra weight. As such, it can still be seen as a net advantage, since it allows for a lower lateral drag craft...

... like this one (with vectored thrust) :eek:

To lift a craft off the ground you need to "do work" - in this case, the "work" is "electrical work", i.e. Watts. A percentage is always a percentage - 20% power "loss" on one big motor is the same as 20% power loss on eight smaller ones. Nevertheless, I see what you're getting at, but I think...

@windhorny: this chap - http://www.myresearch.lt/blog/onboard_camera/onboard_camera.phtml#Anchor-Positionin-41640 - has done a lot of trials with mechanical gyros. @bart: thinking about it now, there's four possible approaches (that I can think of). You could: 1 - regard the total system...

Biggest MR I've seen is a quad - 17" or 19" props, can't remember - all rotating the same way - yaw control with rudder vanes under two motors. Yaw control seems to be the limiting issue with many variations/sizes/weights.

:confused: aluminium plate? Wouldn't have any effect at all, surely? Google "EMI shielding" - the loony brigade have EMF shielding fabric (for making EMI-shielding clothing and for use as wall paper so the Martians can't get you - really!)
