It does a 5 metre circle around the POI, right? Fixed at 5m? So do you have to judge that you're 2.5m from the POI before flicking the switch?

Sunny Portugal :-D

I believe the wind stability thing is related to there being four columns of fast-moving air rather eight. Each of these columns represents a sort of "resistance" to disturbing wind. The entire question of redundancy is a tricky one - so many variables in play. What can't be denied is that the...

This doesn't make any sense to me. Analogue servos should never be driven with any frequency except 50Hz - period! Digital servos will always accept 333Hz, but not 400Hz. I doubt it would damage them (like analogue over 50Hz) but it may well confuse them. So why 50>100>200>400Hz? Seems like an...

We got there ;-)

Ah! I see now! And you're in Europe (by the time you quote) - so the UK link for Misumi is the relevant one for you. Misumi are not cheap (and it's a bit of a pain setting up an account) but it's a very convenient source for those "special" parts. Is the 8mm shoulder exactly 8mm? Try here...

I'm still confused about the "8mm washer" part!?

Easier in native metric units on the European site: search for part # TWASS16-6-1 here: http://uk.misumi-ec.com/mech/

So the Graupner prop has an 8mm bore? with an adapter for it to fit on an M6 motor mount? The flange of an M6 flanged nut (nyloc or otherwise) is 14.2mm diameter. Would that be big enough? Otherwise, you could go with a "washer", but actually what you need is a "shim" (sometimes called a...

I'm confused - you're saying 8mm, but an M8 nut is 13mm across the flats (i.e. uses a 13mm wrench). A 10mm wrench means it's an M6 nut.

Sounds like you need a "flanged nut": http://www.google.co.uk/search?hl=en&q=flanged+nut&meta= Or are you wanting something that's bigger "across the flats". You shouldn't, in the sense that metric hardware is carefully sized so that the wrench size is correct fr applying the correct range of...

Errmm... no - not a "nice" article at all. An ego-laden, self-promotional distortion of reality - yes. See the topmost comment after the article - "Jeremy Esland" - that's me ;-) That man is one of the most unpleasant characters in this "business". DIY Drones steals open source work from...

Agreed - "the DJI disaster" should be in the curriculum of business schools as an object lesson ;)

Off topic but... that second video leads to a website called onlyflyingmachines.com - which makes one of the dumbest mistakes that a shop site can make: where the f*** is it? China? Singapore, Greenland? And the prices - "$": is that US dollars, Canadian, Singapore, Hong Kong, Australian, etc...

Ha!Ha! I've just noticed that the product photos on the Zenmuse page feature a Zeiss 21mm Biogon - an "unsupported" lens :D

From http://www.spyhawkfpv.com/ Scary!

Yep - and Google happily lets these scumbags advertise with them!

Apart from the odd multi-thread, I find this very interesting. He appears to be a photographer wanting to fly a 5DMkII and prepared to spend good money on a good solution. Significantly he appears to have little knowledge of RC or multirotors. As such, he represents the "next market" for AP MRs...
