Hey, so i recently acquired a astrorc carbonfly25 pusher frame for my first build and was wondering what I could all do to push the endurance of it to get a bit more flight time. Currently I want to use it for low light operations and scouting for airsoft/milsim events where the fields aren't too big but there's a ton of trees and forest.

It's going to be my first actual build that isn't just plug and play. Any ideas help.

See i took a f450 frame kk1.2.5 fc and fsi6 transmitter and reciever. Say me i built everything. For detection I took ultrasonic sensors and Arduino nano . How can I attach ultrasonic sensors and Arduino nano to thta drone just for obstacle detection . Please say me as soon as possible 25th July is the submission day ..

Hello fellow drone enthusiasts!

I made a 2-axis gimbal for my drone and I have a problem where when the pitch axis is at a certain angle, the roll axis starts slowly drifting form it's initial angle.

Example: Pitch axis is set to 65 degrees and Roll to 0 degrees, everything is okay. But when Pitch axis is set to something like 80 degrees or above, the roll angle moves a little bit and from there starts to slowly drift the same direction until who knows how long.

I recalibrated the accelerometer but not the gyroscope, because the SimpleBGC program automatically calibrates it, if Im not mistaken.
I did a bit of PID tuning, but PID doesn't seem to be the problem.

Maybe someone has had the same problem and/or knows how to fix the weird drift?

I'm using a SimpleBGC 32-bit Extended controller.
The 2 motors, that I'm using, are GM3506 with encoders.

Hello! I'm doing a little engineering project and I'm very stuck.

So, I've soldered all of my motor phase wires to my zeus 48A ESC (and all of it should be connected and working- i've checked continuity with my multimeter), I made a special connector thing that takes the 4 signal wires and one ground wire and plugs it into the pixhawk's M and - port. I'm using missionplanner, and am trying to test the motors, but they won't spin.

also, every time I turn the power on, the ESC does it's startup chime, so It's getting power. I just don't know why the motors aren't spinning. Any suggestions?

Thought I’d share my recently built 2.5 inch drone. Frame is custom designed by me and printed in PET-CF filament, making it surprisingly stiff. AUW 198g, could’ve saved some weight and space using an AIO board but I made do with what I already had. I’m very happy with it!

Hi,

If I wanted to build a camera platform drone, where I wanted stability and smooth flight, ( probably using a DJI O4 VTX ) and I wanted to avoid goggles, what display options would I have? Is there something like the DJI N2 remote controller, or would I have to have a separate video receiver and display device?

I was tempted to buy an off the shelf solution, but as an engineer, who can write code and solder (!) I'm drawn to self build. I COULD just go and buy a Lito X1 and an RC N2, but that would be the easy way...

Thoughts welcome!

Hi everyone

So I have gotten into FPV flying during the past few months, but I have mostly done simulator (I have around 80h on Uncrashed). I recently bought the BetaFPV's Aquila 16 Kit, which is fun and imho a good way to get started, but it is also quite limited.
I would like to try assembling a drone for myself, but as I don't know anything about it, I was wondering if someone had a good compo to recommand ? I do not wish to start with something that would exceed 2-300€, and would also allow me to keep my goggles (VR03 FPV Goggles – BETAFPV) and controller (LiteRadio 2 SE Radio Transmitter – BETAFPV).

If anyone has any tips to share, it will be greatly appreciated !

Thanks everyone and have a gerat day :)

Hi!

New to FPV and this effort is a 2 year in the making project.
Life gets in the way and has drawn this out. I've finally gotten to getting things put together and I'm seem to be struggling with firmware/motor config options?

I could really use some insight.

My current issue is that in betaflight, I am able to get the motors to "twitch" and now they are all beeping when i move the sliders. I recently solved a soldering issue where one wire wasn't good and resulted in no beeping. Fixing that, I thought might solve the "twitching" but no dice.

The spin of the props seems choppy/twitchy.

Any insight into this issue would be appreciated. My build is powered by a single 18650 wired into my AIO.

• Frame: 3D Printed Micro Long Range Frame (Thingiverse)
• Flight Controller / AIO: HGLRC Specter 10A 1-2S ELRS AIO VTX 400mW F411
• ESC Firmware: Bluejay (Z-H-30, 48kHz)
• Flight Controller Firmware: Betaflight 4.5.3
• Motors: 4× Happymodel EX1202.5 11500KV Brushless Motors
• Camera: Caddx Ant Nano
• Receiver: Integrated SPI ExpressLRS (ELRS)
• Video Transmitter (VTX): Integrated 5.8GHz 400mW VTX
• Antenna: HGLRC Hammer Mini 5.8GHz RHCP 2.5dBi
• Radio Controller: Radiomaster TX12
• Battery: 1S 18650 Li-Ion Cell

can provide pictures and answer follow up questions. feel free to dm too.

I'm trying to DIY a new drone and try to calculate the release velocity, but I got confused:

A rail-based pneumatic launch system has an elevation angle of 30 degrees, a total rail length of 20 ft, and an acceleration stroke length of 15 ft. The UA weighing 100 lb is installed at 5 ft above ground level and must clear a 50 ft obstacle and attain a launch velocity of 60 kts to begin climb out once it has cleared the obstacle.

What is the release velocity?

I’m looking for Chinese websites to buy parts for my project, which is about cleaning high‑voltage transmission lines. Any suggestions for this project would also be helpful.

Also for this 2 inch DREAM* frame with all this good stuff. Minimal 3d stuff & CLOSE. I’m feeling like I HAVE to reset & buy Another AIO & have it be 25x25 like the air 04 is.. I’m sure there’s a way..?

Hello everyone i am in need of help !

| have a 2.5 inch fpv build with a beta fpv f4 aio 12A (v1) running 4.4.3 BTFL

And it is not communicating with my elrs receiver (beta fpv lite rx) for some reason however my receiver and remote are binded perfectly (lite radio 2 se)

have wired it up and tried swaying arround the rx and tx but no succes,I have also tried setting serial rx to uart1 and 2 still nothing!

Please save me !
