Hey i am from Delhi I had a drone which works fine but I accidently totally wreak ed it's body evrything works fine but now it doesn't fly can't find any good design for it and can you also suggest any good 3rd print shops in delhi

This is the drone can anybody help

Built her a few years ago. Had issues with random fly aways i still haven't pinpointed the cause. I know it's the tune. Wish me luck

Hi all,

I'm hoping to get some advice for my son's final-year high school project.

We’ve already had a failed go where we’ve tried to get all the parts on a 3.5 inch frame. But that was a nightmare.

We need some help!

He's coded an AI agent on Linux that runs on a Raspberry Pi Zero 2 W. The goal is to show the agent can fly a drone. It's a software project, not a hardware one.

We'd like a ready-to-fly drone, or a larger frame that's quick to build, that a Pi can control.

Did some research - would something like the HolyBro x500 work?

A few questions:
1. What ready-to-fly drone or flight controller setup would you recommend for this?
2. If a larger frame is better, what size and build would you suggest?
3. Is a Pi Zero 2 W realistic as a companion computer, or should he go for something else?

We're in Auckland, so if anyone local is happy to mentor or help, we'd really appreciate it. Thanks!

Happy to pay for someone to help us with soldering etc too. We’re proper newbies

Honestly I think I can officially say this frame is complete

Last thing I added was splatter gaurds with vent holes for cooling and wing plate to replace the go pro mount because I won’t be using one any time soon

Any suggestions on a name would be cool

Hey everyone! I'm planning a budget drone build in India.

What's the cheapest reliable flight controller and radio transmitter + receiver combo you'd recommend?

Are budget AFHSS radios still worth buying, or should I go for ELRS with screen?

Looking for affordable options with decent range. Any suggestions?

My first drone

Hi everyone, I’m based in Simi Valley with a workspace in Camarillo. I’m working on a Holybro X500 V2 project involving camera integration, companion computing and local radio communications for inspection and remote monitoring.

Feel free to comment or DM with your location and what you’ve worked on.

designed these yesterday

Testing today

Hopefully they stop my stack from getting so dirty and maybe make my frame a little more aerodynamic in certain maneuvers

Hey, I've connected a DJI O4 standard unit to my SpeedyBee Bee25, and the video appears fine, but I can't get the OSD to appear. I've set osd_displayport_device = MSP and vcd_video_system = HD as everyone says, still no luck. This unit works great with the F405 mini stack on my other machine, no problem. Connecting the SBUS lead doesn't appear to make any difference.

Btw, the controller is a SpeedyBee F405 35A AIO, the older version, not the V2 with the nice blue heatsink. This is the standard FC for a Bee25.

This board has only two sets of UART pads on the top side, and one is used by the receiver, so I don't know if switching to a UART that is tucked in somewhere else is an option.

If anybody knows where I can still get the manual for this earlier controller, that might be helpful. Thanks as usual!

I am building a small quadcopter from scratch as personal study project. Planning on controlling it over WIFI with my phone. Really need an advice on the layout.

I actually build one drone a year ago for my bachelor's with 2207 motors and bheli ESCs. The goal was to assemble a quadcopter and build a custom controller with a bunch of cheap sensors and Arduino Nano. But it is my first experience building a small one with mosfet drivers)

I have:

- 3D-printed frame and a 20×80 mm perfboard

- 4× 8520 brushed motors with 60 mm props

- 1S LiPo, 850 mAh

- 4× AOD4184 for motor drive

- ESP32-C3 supermini

- MPU6050 (GY-521) as an IMU

- 3.7~5v booster

My question is - Where should I place the battery, IMU, ESP32 and MOSFETs. Relative to the frame and the perfboard?

At the moment, I am thinking about placing the MOSFETs in a line & esp at the end of the perfboard + strap imu and converter at the top of the body.

A few thoughts:

- I am planning to mount the MPU6050 on a piece of foam/sponge.

- The C3 is single-core. I’m considering something dual-core

Thanks for any pointers!

UPD: I have just realized that the description was too vague and uninformative, added a few dets

I am no electrician or engineer, have been learning as I break shit as I go in this hobby and I have never had the need for a crimping tool, but I am frequently running into scenarios where it would be useful to have one for customizing builds and repairs. I don't want to order the Amazon special and waste money, what's a good crimping tool for working with these smaller thin wires? I imagine it would save some money in the long run as well.

Im (34M) looking to get my first drone. I have been going out with my grandfather to his local rc club since i was 4. Now that I am outta the military im wanting to get a drone. For both practicing indoors and to fly outside.

thinking of fun career pivots as healthcare burnt me out and ill be immigrating to ecuador.

noticed ecuador has relatively lax commercial drone licensing requirements and some niche agricultural applications.

could be a great apocalypse skill and a way to explore a beautiful country, maybe even ingratiate myself with new neighbors if they need a favor etc.

IWTL from scratch, responsibly, methodically, how to fly drones at a commercial skill level. Where do i start?

Hello, I'm going to Montreal for a few months at least and I was interested in learning about 3D printing and also DIY drones.

 I'm looking for some communities in Montreal that have a "hacker space" to do so. For the 3D printing, I obviously don't have a printer and was looking for "shared" ones (of course I'm willing to pay for membership or fees). I guess if those places exist, they also have communities, which I'm very interested in joining.

I'm a developer by trade and I've already done some tiny projects with a Pi and soldering on boards.

I'm French, so if those communities are French only, np.

Hi everyone,

I'm building a custom hexacopter and having trouble powering my SIYI MK15 Air Unit. I've replaced the original BEC, but the new one also appears to produce almost no output voltage. I'm trying to determine whether this is a BEC problem, a compatibility issue, or something related to my CUAV PMU Lite 2.

Hardware

- Flight controller: CUAV Pixhawk V6X

- Power module: CUAV PMU Lite 2, 5V version

- Battery: 6S LiPo, 22.2V nominal

- Radio system: SIYI MK15 Enterprise Combo

- New BEC/power module: SIYI 4S–18S module advertised for the HM30 Air Unit

- Connections: PMU Lite 2 battery output → XT90-to-XT60 adapter → BEC input → XT30 output → Air Unit

My original SIYI BEC appeared to have failed. It received approximately 22.2V, but its output measured around 0.2mV, so I ordered a replacement. Unfortunately, the new BEC appears to have the same problem.

Measurements and symptoms

1. The PMU Lite 2 battery output measures approximately 22.00V.

2. The XT90-to-XT60 adapter also measures approximately 22.00V.

3. The new BEC's XT30 output measures approximately 0.01V on my multimeter in DC voltage mode. I still need to verify the reading directly across the BEC input and repeat the output measurement with the Air Unit disconnected.

4. The Air Unit does not appear to power on, and I cannot establish the expected connection through QGroundControl on the MK15 monitor.

I noticed that many setup videos show the older CUAV PMU Lite 1, while my setup uses the newer PMU Lite 2. According to the specifications, the PMU Lite 2's battery output carries battery voltage, while its 5.2V regulated output is on a separate connector.

I don't want to assume the PMU Lite 2 is defective, but I'm wondering whether there is something important about the power path or connection that I'm missing.

One additional uncertainty is the Air Unit generation. My seller described the unit as an older MK15 Air Unit, but the physical unit does not clearly identify itself as either MK15 or HM30. The replacement module is advertised as a 4S–18S HM30 power module.

Questions

1. Should the PMU Lite 2 battery output work with an external SIYI 4S–18S power module in this configuration?

2. Could the newer HM30 power module be incompatible with an older MK15 Air Unit, even if the battery voltage is within the module's input range?

3. If approximately 22V reaches the BEC input but its XT30 output remains near 0V with the Air Unit disconnected, does that point to a faulty BEC or another possible issue?

4. What exact wiring or measurements would you check next to identify the fault?

I would appreciate advice from anyone who has used a SIYI MK15/HM30 with a CUAV PMU Lite 2. I can provide photos of the modules, labels, connectors, and wiring.

Thank you!

The battery seems to have gone too low on charge, and it now wont charge when i plug it in.
Does someone know how i can bring it to life?

Hy guys, I'm new in this world and I don't know anything, for real.
Anyway I decided to try and build something, my dream is to build a really fast plane, the problem is that I probably underrated the project complexity. I already bought the motors and are the AOS Supernova 3220 1000kv. I know that these engines are crazy good but I probably made a mistake buying them because now I don't know what to buy. I'm using ChatGPT to help me but every prompt I text he gives me a different answer, I feel like there are a lot of components that are compatible but each one has different pro and cons depending on the focus. The escs that Chat suggested is one Hobbywing FlyFun 120A V5 for motor, do you guys think that these are good or not? What size of battery should I buy? I know I'm probably gonna be roasted for buying these motors before thinking of everything else but I thought I was on the right track. Thanks!!

Been having issues with telemetry over Mavlink, LoRa devices, and Sik. Wondering if it’s worth the price to upgrade.
