It's pretty crazy that there's not more monetising (gov. Regulating) going on with drones and joe P. They could basically become a small, portable, flying, exploding, peaceful message from the prophet M.

The M actually looks like an icon a drone would have.

It'll get used that way once then regulated into the ground. Like everything else in the history of nice things.

The only thing you gotta watch for is not over discharging your source pack. All the packs I buy for general purpose electronics have over/under current cutoffs, don't RC packs have that?

He's probably going to just hook it enough to tumble it off the roof into a billion pieces below, but worst case if it also gets stuck, now there's a thousand dollars worth of drones up there, and somebody is going to care enough to make them all come down.

A phantom with 4m of paracord with a triple hook at the end will mosdef be able to hook your drones off that roof. It'll prob crash in the process, so bring a camera.

Up to you. Grass is greener and poo poo like that.

I prefer dRonin, because for one it deals with normalized values everywhere, using a formal control approach, instead of that MultiWii poo poo of wrangling raw gyro values into ESC commands by force that *flight inherited, and the dRonin guys rely on logs and math implementing stuff. The two most active devs are also actual control system engineers, and one even has a PhD in related stuff. Also, there's the autotune, which works well in most cases (but not all).

BorisB is getting wiser and starts to formalize the approach in Betaflight, by introducing more and more normalized math. He's even conceded that this fast loop times is bullshit, after doing open loop response tests manually (i.e. one of the things dRonin's autotune does), but still insists oversampling the gyros a lot is a good thing (which it is not, you cancel the ostensible advantage by running strong lowpass filters).

Cleanflight seems having gotten stale, from what I gleaned recently due to unrelated things.

Taulabs is dead.

OpenPilot is even deader.

Raceflight are retards.

I don't think there's anything else that runs on the standard STM32 MCUs used in most recent flight controllers. If you want to try something else, I'd suggest to go with Betaflight (--edit: They have CC3D builds).

Do you have a strong opinion on APM?

Stanford University has a code-commonality tool to identify what its name implies. Someone ran it over Raceflight and Cleanflight. Apparently the firmware part of the Raceflight codedrop matches Cleanflight by over 60%. Some complete rewrite that is.

Betaflight is really way above my pay grade. Every time I feel like I'm learning how to set it up and tune it, something else sets me back.

I've been having issues with my motors pulsing and vibrating along different points on the throttle, so today I went on to a local chatroom to try and figure out the issue. After going through every possible mechanical and software solution, someone realized I was using the current BF configurator with the not-current BF version. The result is my PID values being written at 100x what the configurator shows. So even though my PIDS were tuned against each other and the quad flew reasonably well, the ESCs and motors were literally (solder was flowing) burning up. I'm expecting a huge improvement with some tuning once I take it out tomorrow, at which point I'll probably fly it full-speed into a wall.

For all of that stuff step 1 of troubleshooting is always "are you running the latest everything"

Yeyyyy, got my transmitter and camera, and it all works. Happy times are here again

One question, and one I should have asked a while ago: with the battery strapped in this thing is really back-heavy, at least from my balance-it-on-my-finger test. Explains why I have to pitch forward pretty hard to take off without flipping on the back, anyway. Is this something I should try to correct, like... I dunno, with some sort of weight on the front or something, or just leave it be?

Generally the battery is slung under the CG.

Two observations from this evening

- Funny how batteries last a lot longer when you're more likely to be at about 30% throttle than 70% at any given time

- Jesus christ and all his saints flying FPV is loving terrifying

Now you're getting it.

Admittedly a $300 DJI carrying 2 pounds of dynamite is a pretty scary proposition.

A DJI is nowhere near fast enough to avoid small arms. I'd be way more wary of something like a 250mm quad with a little HE and a frag sleeve. You could hit a phantom with irons pretty reliably. Once a good 250 racing frame starts hauling, not a chance in hell.

evil_bunnY: Apr 2, 2003

Gopro means 5 or 6 inch at the minimum IMO, and there's millions of decent frames for that. The problem is that getting into acro miniquads you need all the ancillaries and that means being out 500+ at the low end.

My short cutting from almost 2 years ago just came back and bit me. I wired the LED strips in my flying wing backwards, so instead of digging them out and fixing it, I wired it opposite at the battery plug (so black is pos, red is neg). So while this thing looks great, it also let off a small puff of smoke when I plugged it in. Wonder what the odds are a TS5823 Vtx is protected from reverse polarity :/

The little "wings" sit on the battery, with two velco straps holding it down.

That pod looks loving neato.
