Nice video - would be a killer if it was edited together with some ground-based footage. Perhaps a bit marginal on the safety ;-) I'm sure you did a full Risk Assessment (H&S joke :D) Was that a Zenmuse? There seemed to be a few horizon issues going on.

Typically confusing piece from the BBC ;-) - the guy is not a "Danish enthusiast" but an employee of Resource UAS, a UK company offering UAS training to military and government. The folding quad he's showing is a Huginn X1 from Denmark.

Breezemont - not sure what you mean, but... There is, surely, a distinct difference between foamies and autopilot systems - in terms of time, money, expertise and so on. Any functional autopilot system represents a massive investment and has a huge "value". Imagine a commercial company - how...

Yep - sounds like a good plan - although it wouldn't hurt to use some (appropriate) Loctite to hold the bearing inner race on the "shaft". Keep us up to date :)

jdennings & ChrisViperM - two well considered, intelligent responses - I thank you - indicates (to me) that the time spent was worthwhile :) Definitely both, but more calculation. Certainly he's the type of character that revels in being contentious and feeds off the sycophancy around him. He...

Here's something interesting: http://www.myresearch.lt/production/DirectionFinder/DirectionFinder.phtml

Some other thoughts/observations: - why not extend the bearing block so it meets the opposite plate? This would improve the rigidity and save a couple of alu spacers. The roll bearing block looks wider than it needs to be. - I presume you're going to fillet the sharp corners? - Rather than...

IMO - no, not noticeably - the additional thrust would be more or less cancelled out by the additional weight. What could make a worthwhile difference is higher pitch props on the bottom - like JXF 14x4 on top and 14x5 on the bottom. (In eCalc I enter this as "14x4.5", i.e the average pitch.)

Hi Neill - There's nothing showing on the eDrawing about how you intend to accomplish this. Can you give details? Jeremy

Re: your long post above about "US Made" - I believe (according to information on the DIYD site) that the 3DR factory is in Mexico, which is not (yet) part of the USA.

I agree that the atmosphere here is generally very positive and productive. But that's not to say that the outcomes of threads/conversations are always satisfactory. A few things have surprised me - like I recently posted a link to a Code of Conduct published by the largest independent UAV...

Absolutely :)

Plausible deniability. Yep, works well, that does. Very convincing.

I'm on the edge of my seat! Wow! Really serious issue, that one! ROFL! Like I said - Chris Anderson's Unpaid Programming Department. Exactly! Chris Anderson wants the board to a) serve as the ego-reward for his unpaid programming department and b) serve as the free marketing and promotion...

Totally agree with Mombasa on the so-called "tilt shift effect" - old, tired, distracting, clichéd - especially when it's done in Photoshop after the event. Hopefully it will die out, along with "grunge HDR". :) Btw - just 'cos I'm a pedant on these things - it's not a "tilt shift" effect since...

Now I'm suspicious - I PMed you with a link to follow but you seem overly keen to make your defence of "Chris Anderson Inc." public, which (together with the fact that you're a brand new member here) suggests your objective is "damage limitation" on behalf of DIYD.

We should drop this thread - nobody wants a mud-slinging match. I've said what I've said and I stand by it.

I'm not going to quote examples - but if I understand correctly and you're a developer within the DIYD "community" then you must have your head buried in the sand ;-) If you're unaware of the unrest with the ranks of Chris Anderson's "unpaid programming department" then ask around. Or ask some...
