This is my first scratch built quad. As of today the longest flight might have been 5 seconds before not so gracefully flipping and RTH via gravity.

I have checked and double checked all connections and settings (iNav). To my novice eye everything looks and spins according to design. It is currently set to angle mode and my genius self didn't try any other modes. Build consists of

CHNL 6C lipo

10x5x3 props

Generic 10" carbon frame

GEPRC GEP-M10 GPS

ELRS 2.4GHz Nano RX

Generic F405 FC (DAKEFPV405) and 60A BLHeli-s ESC

The first flight if you can call it that made it about 15' before flipping and the rest of my attempts of thwarting gravity resulted in immediate flipping. I am attaching my black box files if someone could kindly have a look and tell me what is going on or how I'm contributing to the issues. Thanks in advance.

Can i make it work without the switch? Here in my place cant find anywhere that sells the part. Can i make it myself diy style?

I’m looking to create my own ESCs, but it would be great to have a reference point and control to test against.

I’m having a hard time finding any existing ESC schematics for available ESCs.

Anyone have any they are willing to share? Single ESC is ideal, but 4-in-1 would be better than nothing, which is where I am at currently.

Thanks!

Hey guys, I'm new to drones and I'm trying to build my very first one. I trying to do something more focused on long rage rather then performance, the cruising velocity would probably be 20km/h, and I was looking at Li-ion batteries cause from what I understood they have higher energy density then Lipo. The only thing I'm worried about is the discharge rate, the drone due to some payload is very heavy (around 7kg?) and I don't know if Li-ion can give enough power to take off. The drone will follow a chosen path so no sudden change in direction or other movements, but it will cover it multiple times a day so it'll need to take off multiple times, also the payload isn't always there for every trip. Currently I'm planning to use racerstar 700 kv with 30A ESC and an APM 2.8. , but I honestly don't know if it will stay in the air lol. Do you think a 6s4p of 21700 can do the work?

Looking for — return to home without the risk of collision

— the ability to hover without the drone moving

Having trouble figuring this out… any help appreciated

Hey all,

I’m considering buying my first pair of FPV goggles, I was considering the Walksnail Avatar Goggles from caddxfpv. Does anyone own these or think there’s a better option on the market?

I was given an old tarot 680 frame and wanted to spend my time turning this 6 arm drone skeleton into something usable

I am aware drones like this are not recommended for first drone builds but I fell in love with the model and was up for the challenge plus something to show off👀……
I’m looking for long range to get some nice footage of my area and parts that won’t fail mid flight and are compatible with eachother

Looking for the following to start flying • battery • 6 motors • 6 motor speed controllers • Flight controller • GPS with compass and gyroscope for a smooth flight • long range fpv camera • something to adjust camera while in the air via remote

Looked into my build and have parts picked out but want suggestions from the diy drone community Excited for the day I complete this thing wether it’s next week or next year🙏

Hey everyone! I need help with an issue, I am making a custom flight controller using an esp32 based on this repository: https://github.com/pratikPhadte/ESP32-Flight-controller-.git, I adapted the code to try and use the drone with a ps4 controller at close range, just like so https://github.com/juanan2402/drone.git, however, when I start increasing the throttle, one of the motors stops running, does the code have anything to do with it, and if not, What other issues can be the cause of this?? any feedback is appreciated.

Hi, I am a First Year college student taking part in a survey drone making competition. I am responsible for researching and providing options for the real time data transmission and all other communications. I need a transmitter and receiver compatible with pixhawk flight controller which can switch between 2.5 ghz and 5.8 ghz bands and with a range of over 1 km. What protocols and things should I read about and what are the available options in the market? The data transmitted will also contain Lidar data if that's possible. I have never made a drone before and got the role based on other technical research I had done earlier. Reading some things online has made me more confused than ever. Any help is much appreciated.

I'm looking for the easiest way to get the feed from *either* FPV goggles or a controller with built-in display (DJI) to a second monitor for viewing by friends/spectators. Ideally wireless would be great but if I need to run a USB/HDMI cable, I'm not opposed to that either.

I know this is kinda broad since there are many brands and models of FPV gear. I see a LOT of products on Amazon that claim to do wireless HDMI etc., and most of them have bogus reviews. I ALREADY have a nice battery powered monitor with HDMI input.

What have you guys used successfully?

Thanks!

Now, my planes weight is 3KG And The Thrust I'm getting from a motor is 7.5KG But it's is 420KVA Using 16×? Inch propeller

The original design Was 580 grams weight. 900 Gram Thrust. But it was 2200KVA Using a 6×4 inch propeller.

What I really need guidance on is:

Does the KVA Rate really Matter in acceleration?

Or does the Thrust matter?

And so what if I have lower 420KVA on the stronger 7.5KG motor? As compared to the 900gram motor that gave out 2200 kva

Does lower kva but with higher thrust make a difference?

I am starting my new project to build the drone body by generative design and use raspberry 4 and yolo AI for face detection So any advices ahead

Looking for a supported(quad+ dual esc + inav ), low soldering, available FC given F722 will soon be deprecated.

I watched Pawel’s podcast and he’s recommending at32 f435. Are there any others that will probably be a good investment?

Also my first post in this sub. Please be kind, sorry if this is listed elsewhere, I didn’t see it pinned. Source: https://www.youtube.com/live/U2XwRXuzWyg?si=HYO3d8aNu5_8cW2i

"I'm having trouble with my Pixhawk 6C not recognizing the battery. I learned that I should change the values of 'BATT_CURR_PIN' and 'BATT_VOLT_PIN' in the 'all parameter tree,' but I can't remember how. Does anyone know?"

I am building a drone to drop fishing lures. I am using a cube orange along with its base bored and my receiver/controller is a Siyi MK15. I am trying to run QGC on the controller.

So far I have gotten my motors to connect and I can control them on QGC. I am able to view the camera feed on Siyi FPV but I cant figure out how to hook it up to QGC. So help would be appreciated with connecting the camera to QGC and setting up controls for the gimble.

My servo is connected to the aux rail right now. I have power with the correct voltage also running to the aux rail. The servo is getting power but I can not figure out how to configure buttons to actuate the servo. After that gets figured out I will need to restrain the servo to a certain degree of movement so the drop pin does not fall out.

Any help/tips would be appreciated, thank you.

I found some jhemcu vtx that neds 7v or more to power. My FC have only pads labeled +5v and vbat. If I understand correctly “+5v” pad doesn’t mean “5v and more” and I should use vbat to connect my vtx.

(flight controller k-22 ) Transmitter is fkysky fs-ct6b

First it was showing no signal for all , then I rechecked the signal and now it's connected but showing no signal only for auxiliary , even the armed part is done

I've my review in 1 hour

Please help guys

I cant figure how to get it to connect and turn on and when I plug it into the one in the side everything turns off, I'm trying to use my laptop to upload live waypoint missions, last question are you able to use inav with a ground station idea or is ardupilot the only way right now, I don't mind either

Hello, I am still a newbie. Currently fly with DJI O3, controller 3, and goggles 3. I'm starting to take interest in long range, and i am interested in iFlight Helion that also has O3 air unit.

But the receiver is what got me confused. It has option for ELRS and TBS, and TBS Crossfire Diversity NANO Rx interests me. But i am assuming that does not work with DJI controller 3?

But my goggles 3 should still work with the O3 air unit right? If anything, I would just have to get a new controller thats compatible with TBS Crossfire Rx? If so, which controller do yall recommend? Thanks in advance

I am trying to build my own drone, the question is what battery should I use that is strong enough to last a long time.

Tq To those who are willing to answer

Hi everyone, I’m thinking of starting my first DIY FPV drone build and I’ll probably use a kit that includes most of the components, including the FC.

I’d really like to do some coding myself for this project, I thought about including a telemetry module that I’ll make myself. It should just be able to read sensor data onboard the drone and relay it to my PC. Has anyone done anything similar and can share their experience with it?

Reading online, it seems like most FC components already include this functionality (+ a transmitter that you’d need to attach). I’m just thinking of doing this because I want to code something myself for this project, not because it’s the more efficient way to do it.
