Does the nature of the structure and land prevent you from utilizing a pole saw with a GoPro knockoff attached?

It's a pain to get on the roof and I just want to make sure things are ok up there (be able to see it "for myself") and then call in a contractor if needed to fix stuff.

Gopro and sticks is good, but if you have the cash and want a drone Mini 2 is a good choice. I'd bet you'll fly it more than just gutter checks

I have a mild interest in printing and building this Raptor 2 RC car, because of the four independently driven wheel controlled by some STM32 based control board. The idea is to have a platform to mess around with coding RC things and control algorithms. Question now is two fold: RC cars typically have these large heatsunk ESCs, from what I can see, which seem made for that specific purpose. Do these meanwhile also come with things like bidirectional DShot (and with that RPM telemetry), or is that still just something quadcopter specific? In turn, why can't I just take something like an F55A Pro II from the quadcopter world, upgrade its heatsinking and use that instead?

The reason you don't really see miniquad ESCs in cars is simply the amp ratings: ~50A is enough for pretty much anything 7" or smaller, but it's weaksauce compared to even a basic 1/10 ESC. An ESC capable of driving a 1/10 would be something like an X-class unit, and those cost the same as a good surface ESC. Surface doesn't do D-shot etc because since you drive the motor directly with your finger (as opposed to a flight controller) there's zero point to losing a millisecond or 2 to PWM. Since that raptor splits the propulsion between 4 independent motors it makes sense to use miniquad gear. Surface telemetry seems to be all proprietary bullshit (traxxas, horizon, etc) evil_bunnY fucked around with this message at 20:49 on Apr 10, 2021 |

Hmm, thanks for the info. I'm mostly interested in getting wheel speed telemetry to be able to use it when futzing around with custom control algorithms, e.g. attempting things like vectoring/traction control (if I even get to doing it, because it's also a lot of work code-wise, redoing DMA DShot from scratch and what not). A bidirectional DShot capable ESC pretty much implies real-time telemetry, that's why the question.

Neat! The thing I'd be wary about with DSHOT is the lack of startup optimization and orientation sensors (so startup and low speed are going to feel "coggy" unless you gear way down?). Miniquad ESC aren't really setup to run below flight idle except at arming time, and most of them zonk out if you stall them. You really want a servo system with telemetry.

The rig is laid out for brushless motors, so you'd probably have to rework the drivetrain blocks, and servos would probably bump the cost quite a bit, for a tinker RC car. The original gearing is apparently 5:1. We'll see, I need to get my 3D printer running again first. :[ Also, anyone knows something about blade/propeller theory? Does increasing the amount of blades loosely work like you'd be scaling the prop disc? I'm just wondering, because some people have been messing around with those 8-blade 3.5" cinewhoop props from HQProp on 5" quads, and the whole idea seems hilarious. The prop disc of a 5" prop has twice the surface of a 3.5" prop, but what if latter has 2.67x the amount of blades...

The reason you go to those silly cinewhoop props is noise profile I thought? The tip speeds on a 5" dual or tri blade prop are loving astronomical. Same setup in both vids pretty much. https://www.youtube.com/watch?v=ory6TaxuKlkhttps://www.youtube.com/watch?v=Lh4eMEDJo3c

quadmovr had two of those videos I was hinting at, for instance this one: https://www.youtube.com/watch?v=-F3svnfzKwY Seems they work well enough. I want to try this. --edit: Friend of mine got himself a balancer board. AFAIK, he isn't the type to babysit batteries, putting them away at storage charge levels, so I expect him to plug in batteries at different charge and balancing levels. He's in for a fun time, isn't he? Combat Pretzel fucked around with this message at 18:43 on Apr 13, 2021 |

They make boards with polyfuses now I guess? Hope he's got one of those. Honestly the topup from storage to full doesn't take that long.

I got myself one of those VAS Ion Pro antennas, based on the supposedly high gain they were boasting. I was wondering what was going on inside, given all the fancy multilobe bent wire antennas, and that popular Pagoda PCB one, that came out in the past. But I couldn't find any information. Well I smashed it on a branch yesterday, and turns out it's a dipole with a passive polarizer element, which is just a flexible PCB with some copper traces. Oh how we went from complicated to this:

Goggles work with anything, unless you got a digital / DJI quad, but I’m pretty sure they don’t make the Freestyle in digital so you should be fine.

Just got to figure out which channel the quad defaulted to. It should remember the last channel before power down, so it is set-it-and-forget-it unless you fly with others or are near a system with similar frequencies.

Got around to actually purchasing WebODM the other day. I had it installed via the free method, but this way is a lot smaller on the PITA scale and I may as well kick them over a few dollars. I really need to sort out how to piggy back off of the city’s surveying points as forking over 5 figures for subCM level accuracy for my dumb personal projects it a touch much.

My FAA registration is coming up for renewal, Recreational Flyer Exemption. I like now that you have to provide an inventory of your UAS. What is the model, manufacturer, and serial number of the piece of foam board from the dollar store that I make fly? I have three freestyle quads as well... manufacturer: Parts? It is almost like the people who wrote these rules have no idea how people fly.

Finally received those 8-blade cinewhoop props for my 5". They sound really nice and silent, but holy crap to they draw current for bleh performance (and my quad is a Hyperlite Floss, and therefore not really heavy at all). I guess they'd work better with ducts. And well, they have a 3.0 pitch, so...

Anyone here still doing some more traditional R/C aircraft? I inherited a few aircraft from my old man and decided to convert one to electric. Sig Rascal. Decided to fly it one last time with the four stroke nitro motor and found it had a terrible fuel leak so it got two laps around the pattern and on to the workbench to be converted to electric. One 3d printed motor mount and now it is ridiculously overpowered. The other aircraft is a Sig Riser. I had to get some fresh surgical tube since the highstart was pretty rotten. Someone caught me in the act but filmed it with a potato. https://www.youtube.com/watch?v=vXbf_PHbfo4 Decided more recently to finish the four channel wing for it. Spoilers and ailerons should be a nice addition. helno fucked around with this message at 00:06 on Apr 30, 2021 |

I'm really surprised that no one has recreated it. Mike Patey was able to do some of the beta tricks on Draco but it was never going to do a tumble like the Turbo Raven. One thing that really stood out to me was just how much rudder that plane needed and used. It really reminds me of the large scale R/C aircraft that came out about 10 years later in that respect.
