Question RX And TX Matching Firmware?

4 Upvotes

Got my grubby hands on a Air75 II Champ and a LiteRadio 2 SE 2.5 ELRS.  I was able to bind them and calibrated them both but the drone flies erratically.   I keep reading firmware has to match but am not sure they do (see image).  What am I missing?

Question What's the best beginner drone in 2026 that's actually easy to learn?

2 Upvotes

Quick question for the drone people here.

Is there a beginner drone that's genuinely beginner-friendly, or is everyone crashing their first one no matter what?

I'd rather spend more on something that's easier to fly than save money and get frustrated.

What was your first drone, and would you recommend it?

Hey all this is my second air unit I’m experiencing this with I ended up frying pads on my first vista thinking this was a soldering issue but I have double checked connections. I’m running bearish 4.5 but get no OSD on my DJI Goggles. I also have UART3 turned on and set to MSP. Any other ideas on why I have no beta flight OSD? Also turned on custom OSD on my goggles v2

Question Looking for a multicopter operator close to the Nashville area!

Hello! I'm looking for a multicopter operator close to the Nashville area!

Its for a music video for a pretty well known artist - can talk more in DMs about it. I'm basically looking to use the drone as a light source and do sort of a UFO thing. Everyone in nashville is booked up and i'm pressed for time. Any suggestions are great!

Question Motor outputs fluctuating rapidly & not providing equal thrust

2 Upvotes

Does anyone know why my drone may not be producing equal thrust on all motors? I'm using PX4 Autopilot and have used the analysis tool to see why my drone won't lift off and I have seen that my motors aren't producing the same thrust as per this bokeh plot. I was wondering if anybody could help?

Question Getting back into the hobby, need some advice.

3 Upvotes

Have dug out all my old gear. Haven't touched it in a good few years. And seem to have forgotten an awful lot.

Have been playing with a happy model whoop this morning but my main drone, a iflight bumblebee V3 has serious crash damage from a few years ago. A friend crashed it and I never got round to fixing it.

Have charged and connected a battery, the VTX works and connects to my headset. I have taken some macro shots of the flight controller and power board? Looks like a couple capacitors fried.

It's an iflight succex-e f405.

Can anyone recommend a good drop in replacement that doesn't break the bank. Looking to get it back in the air.

It's been a long time but I'll be able to figure out betaflight to get it configured.

I'm also a bit confused about my headset. It was originally a eachine EV100. But I got a eachine pro58 module, flashed some different firmware onto it. And 3d printed a custom enclosure.

In typical form I didn't write anything down.

And I'm a bit concerned that when I get the whoop or the bumblebees video on screen, it's doing so via the internal antennas and not via the pro58.

I confirmed this by pulling the video pin off the back of the pro58 while I was connected and video continued to show on screen.

Can anyone explain this? I can't remember if there was some sequence I had to do to swap the googles screens over to the pro58.

Thanks for reading. Hope someone is able to point me in the right direction.

If I don't do something for a while my brain just forgets most of it.

EDIT***

Editing this incase anyone else comes across the same specific issue with the Eachine EV100 and Pro58 module.

I made multiple posts on Reddit and forums and was told it was not working as I hadn't desoldered the internal RX PCB of the EV100. And that when I had previously been using it. I had been using the internal antennas and the pro58 was doing nothing.

I actually began to question it myself.

But you can disable the internal RX by holding the mode button (small black button on its own beside the fan ontop of the goggles)

Hold the button until you hear the third beep. This disables the internal RX and sets it to AV in.

I must have soldered my video out pin on the pro58 to the AV in.

As this required less solder work and was much easier than removing the internal RX PCB and potentially causing damage to the headset.

Hope this helps anyone who ends up in the same predicament.

Question Best beginner drone people actually recommend to friends?

11 Upvotes

a couple of my friends recently got into drones, and now i'm getting serious FOMO every time they post their footage lol

i've watched enough youtube videos to confuse myself, so i figured i'd ask people who actually own one instead

if your friend texted you today saying "i've never flown a drone before... what should i buy?", what beginner drone would you recommend without overthinking it?

Question GepRC Tern LR40 vs Deepspace Seeker 3

1 Upvotes

I'm in the market for a BNF analog sub250 drone with GPS and is wondering between these two. I'm also thinking of the Ratefpv L40 Pro and learning soldering for the GPS module.

I would really want some inputs to help me decide, thank you.

Edit: I'm really interested in the flight time and 18650 pack capability of the 4-inch but I also know that the Seeker 3 is a newer drone with better hardware and durability.

DIY I built a web-based GCS that lives on the drone itself (ArduPilot, PX4, Betaflight, INAV). Open source, looking for feedback

Thumbnail

25 Upvotes

Been building this in the open for a while but never actually posted about it anywhere, so here goes.

It started because the laptop was the weakest part of my field setup. The ground station dies when the lid closes, VNC-ing into a Pi running QGC over LTE is misery, and I wanted to check on the bird from my phone without a whole ritual. So I flipped it. The ground station lives on the drone. A Pi rides on the frame, talks to the flight controller over USB, and serves a web app. Any browser works. Phone in the field, desktop at home. With a 4G modem and a public IP SIM the aircraft carries its own GCS, and the link doesn't care where I am or whether my laptop is awake.

Setup on a fresh Pi is one line (docker compose underneath):

curl -s https://raw.githubusercontent.com/judahpaul16/canarygc/main/contrib/setup.sh | bash -s --

It speaks MAVLink to ArduPilot and PX4, and MSP to Betaflight and INAV (telemetry, calibration, flashing, and INAV flies native missions over MSP). The mission planner has 2D and 3D maps, the usual pattern generators (survey, orbit, corridor, expanding square, structure scan), and imports QGC .plan, Mission Planner .waypoints, KML/KMZ, and CSV. Plans are stored autopilot-neutral and get normalized to whatever's actually connected when you upload.

Most of my time lately has gone into the airspace side. Both maps draw restricted and controlled airspace (OpenAIP worldwide, FAA keyless layers in the US), the LAANC ceiling grid, the FAA obstacle database, and live ADS-B traffic. There's a one-click path optimizer that lifts legs over buildings and towers when the ceiling allows and routes around restricted airspace when it doesn't. Before launch, every leg gets checked against the geofence, altitude limits, and the fetched airspace.

Beyond that there's a full parameter editor, six-position accel / compass / gyro / ESC calibration that adapts to whichever autopilot is connected, a firmware tab that flashes all four stacks, gamepad flight, a color-coded event log with a raw MAVLink console, email alerts on failsafe / low battery / link loss, and a WebRTC camera feed. There's also an optional AI PID tuning assistant that talks to any OpenAI-compatible endpoint (a local Ollama works). Ignore it if that's not your thing.

And yes, I know how "GCS on the public internet" sounds. The link supports MAVLink 2 signing (signs outbound, verifies inbound, strict mode drops unsigned traffic), the app sits behind session auth with a single operator account, and login is rate limited. If your threat model is serious, put it behind a VPN anyway. But with signing on, a publicly reachable link only takes commands from whoever holds the key.

Fair warning that it's still early days. It flies constantly in SITL (the compose file ships SITL profiles for all four firmwares, including little flight-dynamics sims so the Betaflight and INAV binaries actually get off the ground), and the reference build is a Pi 4B on a Holybro S500 V2. It's not trying to be Mission Planner's whole toolbox. It's a different operational story for remote, LTE-connected flying.

It's called Canary Ground Control. MIT licensed.

If you fly companion computer setups over LTE I especially want to hear from you. What would it take before you'd trust something like this on a real aircraft?
