Yeah, because 8 = 7++ ;) Anybody seen the 10" 1000cd/m2 screens they are advertising at Goodluckbuy? Seems interesting, but I'm not gonna be the guinea pig! :)

Two more flights last night. Conditions were dead calm again, and it flew perfectly. I tuned the PID's, and I think I was way out of range before, was the problem. I'll just wait for some wind to see now. But otherwise it flies brilliantly. It's way way way overpowered. It can climb faster...

I get mine at Hobby King. Good stuff. But on my Octo, I just used industrial wire. It's stiff, but the wires are straight so who cares.

You can tidy things up a bit by cutting off the shrink wrap, and turning the DC power lines around so they come out the same end as the motor wires. This would make for a cleaner install. Then just reshrink the ESC's. I bought 6 feet of shrink wrap sized for 40A ESC's for like $5 at an...

I flew it last night, and I wasn't as happy, but maybe it's not a problem. So the conditions were, maybe a 10-15 km/h breeze, whereas the night before it was dead calm. I took off and noticed a twitching. I started working the PID's, and it took a while before I realized I had accidentally...

That's really surprising that you can't at least set it. That's like a single byte in a parameter. So you have to clock the GPS unit? That's silly. Slow to acquire GPS lock? How long? We're just a few seconds now with the battery backup GPS. DJI is really going to have to step up their...

They don't do that already? It's pretty easy to set up a system in the program where it looks at your current GPS location, computes the correct declination for that location (there are look-up tables available), and then goes with that. <cough> Yes, it is. But all he's doing is running...

Thanks. No good overheads sorry, the overlap is ~60mm.

Yeah, I know you're FPVers. I was just wondering if this would be something you guys would be interested in. Sounds like you aren't. That's cool. I haven't had a lot of traction on it. But it's something I'm mostly interested for UAV helicopter use. I want to be able to film video, chasing...

Yeah, OK, I can see that in your video. It is a lot like you're driving a rally car. Sometimes you are over-rotating, and then the velocity catches up to the heading later. Not a huge deal, looks like fun. But it's not ideal if you were trying to film a moving vehicle on the ground. Kind...

DwarfStar flew for the first time last night. It flew perfectly right off the bat. I loaded in some suggested gains, and the results were perfect. I just tuned them up a bit and it's all set. No weird noises or visible vibrations. Smooth as butter, and just a typical APC SF hum from the...

Yes, and I proved it out experimentally as well, accidentally. I did a setup on eCalc using 8 3536-910 motors with 13" props and 2-4S5000 packs, and it said it was fine. I did a bench test to measure thrust, with one motor, drawing from one pack. The watts were too great. The reason is...

I don't think that's a problem, if I'm understand correctly. What I think he doesn't want is this: Dude: "Hey, how do I solve this problem?" Owner of MultiCopterForums: "We already solved this here: www.multicopterforums.com" A response of: Dude2: "MultiCopterWidgets.com has exactly the part...

You can't. That's why closed source sucks. I'm just thinking of putting it in Arducopter, and wondering what you guys think. For sure I would like it for helicopter flying, because flying at high speeds, you really want your tail behind you. I'd use it for waypoint flying as well.

I'm having trouble understanding what you're saying, but it sounds to me that the way to fly is you "fishtail" all the corners. Keep the nose down, creating forward thrust. Kick the tail out to send the thrust sideways. Driving like a rally car. Yeah? This would be different. You'd steer...

Interesting thread guys. I'd like to ask you what you think about a yaw control feature I've been thinking of creating for just this reason. Basically I want the copter to "weathervane" automatically. Basically, the flight controller would automatically yaw the copter so that it is facing into...

Interesting, I just read on RCG that you have the old GPS, and that might explain why you have not had FOD.

Yes, it appears to me the situation is basically this. Doing this as a business is not "legal" according to the FAA, but at the same time, they really can't do anything to stop it other than writing angry letters. While it is not "legal", it is also not "illegal" meaning there is no...

This may all be besides the point in light of the recent announcement from DJI. I hope they have found the problem, though I can't make any sense of it based on what they wrote. This appears to be a fairly extreme system failure, and I'm not sure how the compass unit could cause it. Anyway...

The flight controllers should never open up all the motors to stop the descent, or control the yaw. #1 priority has to be maintaining attitude. Let it fall straight down, but come down straight. There's a pretty good chance that nobody is standing directly under it, but if you allow the...
