That's like they say "How do you make a small fortune racing cars? Start out with a large fortune."

And that is not a $3-500 Tx. That's like a $100-150 Tx that the Inspire comes with. Very simple casing, melt soap bar design, few controls, no display IIRC. Actually, that's the biggest let-down for me. I think the styling of the quad itself is actually pretty cool. But the Tx is like a...

I don't really think any of that has anything to do with this. I think back in the day, the argument was about voltage vs. amperage. AC makes it really easy to step up and step down voltages (using a transformer). So it made sense to use very high voltage, to lower the amperage, for long...

Actually, it's funny because you always hear about that with sine wave inverters being better for electronics. But fact is, I don't believe that's true at all. Most electronics run off DC. So the first thing they do with the AC power, is rectify it. The shape of the wave really should not...

This here strikes me as being a bunch of malarkey. First of all, the typical switching frequency of an ESC is at least 8kHz, even 16kHz, sometimes even more. But that doesn't really even matter. Yes, flight controllers can only provide 400Hz input signals. It's surprising he even says this...

3 phase induction? So basically, and AC induction motor. Not actually that much different than what we are doing now, though the control system is SO much more complicated. My impression based on my experience with industrial motors, is that induction motors are much, much larger and heavier...

How can we comment? They haven't released the details yet. I'm on the edge of my seat. :)

He's not talking about getting rid of Brushless DC. He's just talking about more intelligently controlling throttle application, so as not to over-current the system. I believe this will help prevent loss-of-sync. But I do not buy the argument that this would speed up the RPM response. It...

You guys are all talking about the hardware. I think the most important part of that presentation was the SDK! That was a bombshell. But, somebody said that it's Phantom-only? Is that true? If so, why would they do that? I was pretty much thinking this would totally change the landscape. It...

Which switch is that?

You can sort of do that now with Arducopter, and it could be modified to do exactly what you want fairly easily. Right now, you can change the flight speed during a mission, with fixed speed change commands (they are sort of like a waypoint). But it's something you set ahead of time, while...

This is actually several months old. It's first flight was grounded due to "high winds", which IMO, weren't very high at all at I think 40 km/h? It just shows how a large quadcopter is a really bad system to be using for a job like this.

Yeah, I'm really curious. I love Align RC heli hardware. The electronics are not the best. And their software is often quite bad. Their APS autopilot for helicopters is really bad. So I'd like to see how this one works out. I'd be interested in the frames if I could get them without...

I've had hawks go after me a few times. One tried to grab one of my bigger helis even. Yeah dude, you just try that, let me know how it works out for you. Heli would take it's feet right off. Only question is if it would take down the heli or not.

Success! I got my mapping heli to 2kg (Well, I have to hunt down another ~50g). Just test flew it, and I got the amperage down to 12A in a hover. Well, I got down to 11A, but 12A seemed to be the sweet spot. That's on 4S, so ~180W for 2kg. Not bad at all. So, even though I have half the...

Yeah, it's practically impossible. I think I can do with a helicopter, but probably not a quad. I currently have a Heli, which weighs 1213g "dry" with no camera or battery. I can get a 4S5000 Multistar battery, and an S100 camera on a fixed mount in under 2kg, but it's tight. However...

Yep, I've been tracking this development. Very excited! The 2kg limit is pretty restrictive, but it can be done. I've already stripped down my small mapping heli so that it's <2kg with a camera. VTOL, speeds up to 76 km/h, and 15 minutes flight times, not too bad! I'm also looking at a new...

I can't recommend many ESC's, as I don't use a lot. Right now I have 2 quads, both running Hobbywing Quattros. They're fine. I suspect just about any ESC not running multi-rotor specific code will work fine. I am keen to try out HobbyWing's new Xrotor ESC's.

I don't think there will be a solution to this problem, because the problem does not exist in the Arducopter firmware. The only thing we could do would be to create a slew-rate limiter, which would limit the rate of change of the throttle signal. It would be kind of a silly thing to do, as...

No money shot from those distances. Actually, what's interesting though, is that this actually demonstrates to the people who are worried about privacy that, even when somebody purposefully sets out to shoot porn from a drone, you can barely make anything out, and certainly can't see their...
