where does it say they are brushed? I couldn't find reference to that.

Could be to save costs - brushless controllers are more expensive.

I'm trying to persuade my employers to put some money into the kickstarter, since it is one of our microprocessor cores in the copter.

Because the motors shown in the images are brushed motors?.
Also, no amount of flight stabilization is going to make this thing stable outdoors...it's simply too small.
In their 'demos' it pretends that there's some kind of gimbal on the camera, which there also clearly isn't...and the 10-15min flight time promise sounds very very optimistic. Most micro-quads in that size, without camera or GPS gets you 4-5 minutes.

I've spent the day with a local UAV filming company with a view to going on their payroll as a casual "safety man" for while they are filming.
Blimey! It's a whole new language and severe geekery!
(If I've got it right they are fling a DJI S900 UAS, with a 4k camera)

Yes, that looks good.

I think that when it becomes mainstream and cheap it will also become illegal without a licence.

Ex B-i-L is currently in China learning all about these things before becoming European Chief Marketroid for $CHINESE_MANUFACTURER. They are letting him take $HELICHOPTER "home" at the weekends so they can't be that difficult to drive

The local drone pushers are trying to convince me to spring for an Inspire. I suppose there's a certain balance to be had in owning flying toys that cost more than your car, as well as bikes, but no.

Anybody had hands-on with a Bebop?

andygates · « **Reply #57 on:** 13 July, 2015, 09:03:02 pm »

Welp, the old parrot was finally crashed to flinders and sold to make glue.

Budget is for a Bebop. Just need to breathe deeply and find a lens protector...

You should be able to pick up a DJI Phantom used for cheap now that the Inspire is out..or alternatively get a 3DR Solo.

In all seriousness though it can't be long before some radical straps 500g of explosive and some nails to one then flies it into Dwning Street from a pickup truck a few streets away.

I don't see how you can guard against it (unless you flood the area constantly with a jamming signal).

Quadcopters are going to be such a pain in the arse though, as prevalent as SKY dishes on every estate in the country.

In fact I'm thinking of applying for a patent on a "No Drones/Quad-copters" signs. They are sure to be omnipresent at any public event soon.

The crazy Russian is in fact an American called Kyle Myers and that video is clearly a hoax. The one on the Guardian website might also be a hoax, but it does at least look like it *could* be real...

Thing is, you have to maintain line-of-sight to do so...or at the very least not have anything obstruct the control & video signal...and in built-up areas, relying on GPS may not be possible, so even autonomous flight would be doubtful. There's inertia navigation modules out there, but the known ones require export license, so it'll require jumping through a few hoops to get there.

Exactly. I can't see how security will be able to deal effectively with this sort of Quadcopter.

First Person View

They are flown via a live video stream to the pilot's goggles. I've heard it's very much an out of body experience (and I think I need a go).

Nice Gaff.

Finally getting some decent results with my surveying drone:

It wasn't flying as nicely as desired, but I finally got the camera trigger working decently, so this is a huge step forward. The autopilot records when the camera is triggered and stores the GPS position, which is then later added to the EXIF data, which then greatly increases the speed and accuracy of the photogrammetry process.

It's taken about 6 months to get to this stage, so this is a huge milestone for me and it may enable me to just get the last month or so before harvest to do 'real' tests with.
Next up is converting the camera to IR,so I can do NDVI processing.

To celebrate this, I am now also building a freestyle/racing quad, so I can doing stuff like this :

Julian's dad is talking about a trip up to Brum for this. I"m geeky enough that I fancy it too (although I don't have a drone and Gods alone know that I don't need a new toy-habit).

Anyone fancy it?

That is not a drone - and it's not a quadcopter.

Also - 2:20 - wheeeeeeee
