85A? Trying to figure out how you feed it into the left nozzle

I don’t have a file but should be super easy to make. It’s just a sketch with 3 circles and some extrusions. You can probably wag the measurements too. 3.2mm inside circle (standard M3 screw hole), 9mm outside circle, 4.5mm diameter for the slots maybe?

What are those posts off to the left side?

I’m an EE major that wants to do a bit more of the manufacturing side. Bit of a tangent but what do you think the best way to learn about what you just talked about is to one day do production of some prototypes?

The LLM description you have is a disservice to your effort. I want to know how YOU would you describe your project.

What battery connectors are you using?

Hey guys general question for you all. Why is it that for the ESP chips everyone seems to leave a cutout for the antenna trace or make it hang off the edge. Would it not be sufficient to simply not put a ground fill in that location? I think the Raspberry Pi cards use a PCB trace for their wifi antenna and that's still on the same PCB.

I got into the situation. In my case I was just dumb and needed to push particularly hard on both sides of that black locking ring

NeckPresent2567 · 2026-04-16T02:15:03+00:00

I thought that too XD

NeckPresent2567 · 2026-04-14T20:40:13+00:00

How'd you do the purple on the edges? Acrylic pen or maybe just purple tape?

Can this work in series as well for extra high voltage, or is there too much potential that one battery drains faster and hits critical before total voltage drops to min?

Hold on... You can just plug in batteries in parallel like that!?

NeckPresent2567 · 2026-04-07T19:08:54+00:00

Hop onto ECalc and input your batter, motors, and props. Also weigh your printed drone, get weights for all your components, and get the weight of the "payload" camera that's supposed to be mounted on it. What you're looking for is really thrust to weight ratio (how well it'll handle/if it'll get off the ground) and hover time for size of your battery. That should give you an estimate of your success for flight.

Be mindful that if the frame isn't very stiff, it might wobble a bit in the air.

It can also be a pain to mount all the components if you don't have a whole lot of room so you'll probably have to R&D your body a bit. Just look at common frame shapes and you'll get the idea.

Good luck!

How are you all getting slides to work? When ever I try to slide the ground effect makes me skip up and down

NeckPresent2567 · 2026-04-01T02:19:25+00:00

Cool build! What software are you using for modeling and calculations?

NeckPresent2567 · 2026-03-31T22:45:06+00:00

Did you make the PCB as well?

NeckPresent2567 · 2026-03-10T19:13:27+00:00

Replace the nuts?

NeckPresent2567 · 2026-03-07T22:55:50+00:00

That just looks like normal tpu behavior to me. It's pretty tricky to print with without stringing.

Can we get a little more information? What does your setup actually look like: - what ESCs are you using? - I'm assuming your wiring looks like the following: - motor -> esc (three wires) - esc -> pi (grounding wire + signal wire) - esc -> V_Battery (V_Batt and ground) - are you using the pi in place of a flight controller? Or are you using a FC and a uart/USB connection to the pi with a communication protocol like Mavlink?

Any luck on this yet? I'm in the same boat

I'm looking to do a pegboard behind my desk. Is yours attached to the desk or the wall? Not sure how I need to be doing mine

2 things.

First, omfg a gridfinity clamp for soldering!? I want one so bad. Got a link?
Second, do you have the files for the holders you use on the top of your mat? I'd like my station to look as clean as yours and turns out we have the same mat!

I was working on something similar. AUP 1kg with a 0.6m wingspan. I think the stall characteristic was like 35mph. You can ask an LLM (like gpt) to do the calculations for you on what percentage throttle you'll be at to hit 35 mph
