Big weekend for me with the SRH. I've got it mechanically working well (still with straight cut gears). Then, I finally got it to position hold. I'm the first to get this nailed. Here's the video, but first a quick explanation. At first you see me flying it hard, I'm just testing the...

Wow, not the response I expected after having only looked at pictures of them.

Go with the Futaba. No question.

Yeah, saw that. I'm really happy with my 7". Works great. Good price, only the wait for shipping sucks.

Geofencing, basically you can set up a box, or a cylinder, with a top and a bottom, and if you go outside that, I think you can choose it to do a number of different things, such as to return to home, or "bounce off". I haven't used it yet so I don't know how well or easy it works. I know it...

Yes, absolutely 8 motors. It has 11 outputs (technically 12, but really 11, don't ask) so it can theoretically do an Octo, with 3 axis gimbal, but I don't think anybody has actually done that yet. Automated takeoff, what exactly do you mean? It will theoretically do a scripted mission...

I feel pretty comfortable now saying that that isn't true anymore. I'm not a "company man", and in the past have gone on record saying that the system was not yet "stable". But it is now. I assembled a 3DR Quad, uploaded the code, and didn't touch a single setting, and it flew perfectly...

Agreed. The mounting plate needs to be as widely set as possible. These ball mounts, where exactly do you order them, and how much are they? I have stolen some from an old CD ROM that I disassembled, but would like to get some more to experiment. I'm not really sure if they are better than...

Bowley, the latest code, 2.7.3 has changed from a wide deadband Alt_Hold with fixed ascent and descent speeds, to wide deadband, variable speed. I expect the next revision will have a narrow deadband and variable speed. Actually, I'm not entirely sure how to use X8 mode. I don't see the...

Ok, now that I'll buy.

Just a quick video I threw together showing the loiter performance of Arducopter.

Wow, is WD40 THAT bad? I knew it wasn't a great oil, over-promoted and used inappropriately. But I didn't know it would flat out "ruin" bearings. Dielectric grease is very common, you should have no trouble finding it in the UK.

I've got the analog Weller. Works pretty well. I don't find it "eats" tips at all. I've done a TON of soldering with it. The only thing is that mine is a bit flaky, but I think it's because I got it on Ebay, and it looked like it fell off the truck. Sometimes the station seems to lose...

I don't know if you can solder Aluminum. Google says yes. I'll give it a shot. You can definitely weld it. ;) that would be ultimate. I found McMaster Carr sells bare solid aluminum wiring. Lots of gauge sizes. I could easily run that through an insulating line here at work. Apparently the...

Yeah... I see about $300 up to $600 tops in materials on these frames. Not that I think people shouldn't be able to turn a profit, but I just couldn't bring myself to spend that kind of money for a design that is really not optimized. I'm trying to find these threads as I'm at this point in...

Any update on this ESC? How is it working out?

Now if you used 2 on the axis, opposing eachother, that might be better. Less force on the servo gears in steady-state, but might still eliminate slop. There's a lot of damping now. Damping rates are of course adjustable on these things, via oil weight and piston hole size.

I don't like the felt washer thing because it's dry friction, which means stiction. What you need is fluid damping. And alternative approach to the felt washer idea, is using two washers with a super thick grease between them. Sort of like the friction plates in a viscous limited slip...

I think this looks great. At least equivalent to the any of the pro-hobby gimbals like PH, etc. I do see a tiny bit of vibration coming through every now and then. I also see a some slight shaking when you are descending. I assume the copter is unstable when descending, this is somewhat...

Well, I've been thinking that maybe the problem with the roll axis is simply that it has much higher rotational inertia. Therefore any servo slop will have a greater effect. I would be interested in trying to use an RC car spring/damper to preload the roll axis. Just a light spring. It will...
