recently i wanted to try flying in acro mode but my dad and i saw that angle mode had limited angles so we wanted to try that but when i changed the mode to angle and increased the throttle it just flipped over and now we have no idea what to do now

It’s plugged in I inspected and there is no damage….. light on the GPS lights up like normal but mission planner keeps saying “no fix” even if Im outside I plugged it up the other day and the location popped up mind you this was indoors I’m using the Ublock m8n Module on the Pixhawk 4

Posted in r/fpv as well, but realized this may be a better place...

Without getting into too many details, we do this pinewood derby racing at work every year. The "unlimited" class has gotten out of hand, we're running the track in <1.5sec now with the fan cars. CO2 cars have broken the <1sec barrier. We're doing stuff like pre-heating the batteries to 50C just to get the DCIR down for less voltage sag in the run... So every advantage helps here.

The fan car designs are getting split in two camps, light weight, and big power. (well, all are big power I guess, at best you get 5 runs before we burn up ESCs and motors.)

So I'm trying to find the ESC that has that absolute fastest spool up time. 2 years ago I used the Castle DMR 30/40 and got 2nd place. Last year I didn't really update the design and got 5th place. So I'm looking to see what's out there that may offer better spool up time (and higher voltage...thinking I want to jump to 8S this year).

I'll be doing lots of "pre-season" testing, so I know I'll buy a bunch of different combos, but any suggestions you guys have would be appreciated!

Thanks!

Hi. I am looking for someone who can assemble components on a DJI 450 frame. What would be the best forum to find someone to have this done. Please dm.

I am in the Simi Valley. CA area.

Hey everyone,

I am working on building my first drone and I found this model and I was planning on 3d printing it. But when I check it on OnShape. It had a lot of parts like screws that I dont want to print.

https://www.thingiverse.com/thing:6233066

So my question is, does 3d printing a model require dropping these parts or is this stl file ready for printing?

Hi guys, I’m selecting parts for my first drone and it’s gonna be a 10 inch (for efficiency and stability) long range FPV cinematography build. I wanna mess around with ArduPilot and do autonomous waypoint missions. I’m undecided about stuff like frame, props, transmitter/receiver, and gps, but I’ll probably go with a DJI o3/o4 later when it comes out.

I concerned about compatibility, the motors with the ESC, and the weight of the batteries. I want to know if this platform is making sense so far. Let me know what you guys think please. Thanks.

ESC+FC Stack: SpeedyBee F405 V4 BLS 60A 30x30 FC&ESC Stack

Motors: Performance FPV 3115 Motor - Special Edition - 1050KV (x4 56.2 A)

Battery: Zeee 6S Lipo Battery 8000mAh 22.2V 120C Soft Pack RC Battery XT60 Connector (Weight: 968g/34.14oz.)

So I have several dji drones. I’m wanting to build a 7 or 10 inch. I’m going to enroll into YouTube university and learn to build everything. But I have one question. How and where would I find the firmware/software to make it fly like a dji. If this is possible. At some point I’ll try to become a real fpv pilot but for now I want to try and build a fpv drone for dummies. Thank in advance for any advice or information

I'm doing a project and I was wondering if there is a way to get the video stream received by ground station to another application so I can get openCV to interact with it. Online search has not been very fruitful. I know DJI drones have rtmp streaming but I am trying to go fixed wing.

My drone will contain, a 4in1 ESC, Flight controller, telemetry set, radio receiver, GPS + compass module and camera. Will a power module be required, to connect the battery to the ESC and flight controller?

I am building my first UAV and haven't seen much information online about when or when not PDBs are needed in the build and I was just wondering whether anyone could give me any advice. Thank you

I am making a drone and I want to add a Nvidia Jetson Orin Nano on top of it. The drone is being powered by a 4S 6000 mAh Lipo Battery (14.8V) to a PDB01-V1.2 with XT30 connectors.

The Jetson Orin Nano has a voltage requirement of 4.75V-5.25V, so I need to use a buck converter to step down the voltage. My idea to do this was to use a XT30 to XT60 adapter then connect to a XT60 to DC jack wire that would plug into this Buck converter. Then from the buck converter I would use a USB-C to DC jack wire to go from the USB C output of the buck converter to the DC power port of the Jetson Orin Nano.

Would this work and be safe?

Additionally, I also plan to connect an Intel RealSense d435i and a servo motor claw to the Jetson Orin Nano. Considering all of these accessories, how long would the 6000 mAh battery power the whole system(drone + accessories)

My 12yo son really wants to build his own drone. I have a DJI, and am fairly technical/diy, but I've never built a drone, so don't know where to start for him. He's in a VEX robotics class at school so has been learning basic robot brain, programming, etc. But, nothing flying...

I'd like to get him a kit, that is all inclusive, low entry barrier, but something he can come away with a better knowledge about building drones. Not just a IKEA style "attach arm a to body a", "plug the blue wire into the blue motor".

Any suggestions?

Edit: The only "requirement" is that it flies at his controls. He'd love it to have a camera but I feel like focusing on the "build a drone" aspect is a more important place to start than "build a drone with a camera".

I'm building a UAV with a university team based on the Tarot T18 frame, but we can't find a CAD model of it to work with anywhere. The manufacturer hasn't been helpful. Has anyone here worked with this frame before?

There are definitely differences in build quality between the transmitters I'm looking at, but is there anything that I can make a drone do with the expensive radio that I can't do with a cheaper one? Is the range different between them, or is that more receiver dependent? I don't know what most of the features and specs mean in the listings aside from them both being 16 channels.

On the extreme end, here's a cheap one: https://www.getfpv.com/radios/radio-controllers/radiomaster-radios/radiomaster-pocket-radio-cc2500-elrs-2-4ghz.html

Also extreme, here's an expensive one: https://www.getfpv.com/radiomaster-tx16s-mkii-max-pro-radio-transmitter-w-ag01-gimbals-lumenier-edition-multi-4-in-1.html

There are a bunch of in between options price-wise. I just don't know where to start. I already have a flysky fs-i6x, and I have no idea how that compares to these radio master options beyond max channels being 10 vs 16. I'd like to do long range flight, and I have no idea if the flysky receivers work with the speedybee f405 stack that I'm planning to use in a build or how any of that works together.

Was looking at making an fpv (I know there is no camera, haven't got the budget for that atm)

Hi all, I'm looking for small lightweight motors (max 30g) with oversized bearing shafts for improved impact resistance compared to the 2mm shafts that are so typical at this scale. Something between like 1404 and 2304 in size ideally really.

My use-case is non typical (weapons for small combat robots - mini BattleBots/robot wars) and bent shafts is the biggest failure point.

I've seen the stan fpv 2604s have large hollow Ti shafts which would be ideal - but they're pushing it on size and weight for my application really so was wondering if there was anything similar on smaller form factor motors out there? - but so far my search hasn't yieled great results.

Thanks

hello i need some starting point for ugv controller making. i have my final year project to make ugc remote controler.

now im looking at most used cotrollers witch use RC comunication.

1. i want to know how to make transmiter and reciver (i need to make controller from scrach)

2. how can i add more chanels (what i seen on youtube is mostly 4 or 6 chanels )

3. how can i recive video from ugv

i dont think like expreslrs is good for me because its already finished product but thanks for all information i can get i hope is understantable what i just described

Not sure what im looking for here. Going to build my own drone and Ive seen and heard that this is a good stack. Is this a good price, any other suggestions for controller stack?

I am looking into soon upgrading my first drone, a Crux35 V2, it's currently running an ovx306 VTX, rated at 400mw. I heard good things about the tank solo, so I figured that would be a good upgrade, and since i'm already changing the VTX i thought i might as well switch to the baby ratel 2. Since i haven't done a lot of soldering, and have never touched DIY drone stuff, I would just like to know if the diagram i came up with is safe/correct.

Any additional advice is also welcome.
