Ik this is for rc planes but the recievers and transmitters are universal

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.

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?

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.

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.

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?

Hi everyone I am looking for drone recommendations with the sole purpose of taking progress photos or videos. Some bonuses would be 360 degree camera, high photo and video quality, solid battery life and above average storage space. Any recommendations are welcomed!!!

Hello, I've been looking at joining fpv since I was a kid and never got into it, but now I think I'm ready. My goal is to fly cinematically while I travel and hike, and I want to capture some nice clips of the surrounding environment. The other two caveats are I'd still like to be able to do acro, nothing crazy, and I would like to get my license to do real estate videography. I understand it will probably be hard to get all of that in 1 drone, so I'm looking for something that's beginner-friendly, with likely the DJI 04 Pro, and that can still do acro. I was looking at Gareth Dix's DJI O4 Pro // Quadmula Djinn F25 SP // sub-250 g build and the Nazgul drone. Does anyone have any recommendations for RTF/BNF or builds?

For some context, I've soldered before, still a lil new, but I've put together ham radio stuff and have done my own soldering, so I'm not scared to do that stuff.

** EDIT **

I just want to also thank everyone who has given me good information to think about and things to do. Everyone has been so kind and patient with my questions, so I appreciate it. In an age where people say, "Just put it in AI, yk," I do that too, but I most importantly enjoy gaining information from people in the subject who have hands-on experience and mistakes, and thus far everyone here has given me that, so thank you.

My years old $30 toy drone just broke (bought new batteries which were reverse wired, RIP).

I just want to fly something small and cheap for as long as possible before battery runs out. That means no frill, no camera, few antennas, visual flight only. Just rotors, battery and a radio.

I see some reviews of cheap drones (such as the DRONEEYE 4DV2) with up to 20-30 mins of flight under $50 but these all include a camera etc. I would rather save the weight and fly longer. Do i have any better options?

Been working on this 7in 3d printed fpv frame with NGE themed texts. Frame is engineered to be very stiff. Arms are 11mm CF rods.

I faced a huge problem with am32 firmware I can’t solve.
And the problem is excessive heat- esc heats up like 2C per 1sec and climbes 100+C. I’ve already tried 10 different esc and multiply different settings and none worked well. Some even choose to live it’s own life and makes drone fly into the wall. Others have mosfets unsolder while osd shows only 80*C.
Blheli 32 heats up to 80C and bluejay stays under 60\*C.
I’ve already tried am32 esc with huge sase zone- 12s120a for 8s 45a consumption and still overheat.

Can’t wrap around what’s wrong with am32 and why it behaves so weird. Anyone any insights?

I'm having a weird issue with my iMAX B6AC V2 when charging a 4S Li-ion battery.

The battery is mounted on a drone and the charger is mounted on a dock, so I have to charge the battery while it's still installed. Because of that I'm using about 2m extension cables for both the main charge leads and the balance connector.

Current setup:

• 4S Li-ion battery
• iMAX B6AC V2 charger
• Main charge leads: 12 AWG
• Balance leads: 18 AWG
• Charging current: 4 A

I always balance charge, the battery is healthy, and the cells stay well balanced.

The issue is that the charger reads the battery voltage correctly at first, but as soon as charging starts the displayed voltage jumps.

For example:

• Battery measures 15.5 V on my DMM.
• The charger also shows about 15.5 V before charging starts.
• Once it starts charging at 4 A, the charger reports around 16.0 V.
• It then stops charging when it thinks the battery has reached 16.4 V, but when I check with my DMM the battery is actually only around 16.1 V.

My guess is that the extra cable length is causing enough voltage drop that the charger thinks the battery voltage is higher than it actually is. I used fairly thick wire (12 AWG for the main leads and 18 AWG for the balance leads), but it still happens.

I also read that some chargers can be calibrated, but I can't find any calibration option on the iMAX B6AC V2.

Has anyone run into this before?

• Is 2m simply too long for this kind of charger?
• Would using even thicker wire help, or is there another solution?
• Is there any way to compensate for the voltage drop on this charger?
• Has anyone successfully used long balance and charge lead extensions with an iMAX B6AC V2?

Any ideas would be appreciated.

Asking partially out of curiosity.

We'll I would like to someday get into that business if no one else has done so already.

First ever drone with two gimbaled lenses under 250g?

Looking to possibly getting into walksnail in the future but want to install the moonlight kit into my nazgul xl5 eco but haven't seen anything on YouTube or from basic Google search if anyone has done it yet or if it's possible to fit the moonlight kit into the the xl5 eco any information would be greatly appreciated.
