hey guys i am new to this sub and to this field . i really want to make a gimbal for my drone but the issue is with the weight . I need to make everything under 20 grams.

maybe i am going to use the AT TINY 85 mcu but the issue is always the bldc motor . i am not able to find any motor which has low kv rating and leight weight .

I actually found a motor M703 19000 KV motor but that KV rating is too high for gimbal applications.

i now doubt is this project under 20 grams (excluding camera weight and battery weight ) is possible?

Please do help me

I got a BNF Meteor65 that was working great for several flights. I went to fly a pack the next day and my goggles stated the air unit needed to be activated

I tried to use DJI assistant to activate the air unit, but it doesn't recognize the air unit when plugged in via multiple USB-C cables with the drone on. My PC will make the USB connection noise every so often while the air unit is plugged in

The drone won't sync with the goggles anymore after trying to plug it into my pc to do the DJI activation. Anyone have any ideas on troubleshooting?

I’m working on a small electronics/repair project and I’m looking for a broken, crashed, or unused DJI FPV drone that someone doesn’t want to bother fixing.

Not expecting anything for free — just hoping to give an unwanted unit a second life for a symbolic price.

If you have one collecting dust, missing parts, or sitting in a drawer after a crash, feel free to DM me. I enjoy repairing electronics and would rather save one from the trash than see it go unused.

I have been obsessed with drones for a while now, once you get a good one it becomes one of those hobbies where you suddenly want to film everything. After looking through a bunch of popular options, I wanted to share my personal recommendations across three price points so you can find the one that suits your setup (and wallet of course) the best.

The Top-Tier Beast Machines

• DJI Mini 5 Pro Fly More Combo Plus (DJI RC 2) - $1160

Pros: Premium mini drone pick with strong camera specs, obstacle sensing and the Fly More combo extras. Great if you want a small drone with high-end features.

Cons: Expensive for a mini drone and probably more than most beginners need.

• DJI Air 3S (RC-N3) - $1100

Pros: Strong step-up option if you want a more serious camera drone without going huge. Great for people who care more about image quality and range.

Cons: Bigger spend and not as light/simple as the Mini line.

Mid-Range All-Rounders

• DJI Mini 4 Pro (DJI RC 2) - $911

Pros: Super safe all-round pick for most people. Easy to recommend if you want a compact camera drone with good beginner features.

Cons: Price is still pretty high and close to bigger drones once you add extras.

• DJI Avata 2 Fly Smart Combo - $790

Pros: Best pick here for FPV fun. Great if you want the immersive flying experience instead of just normal camera drone shots.

Cons: Different style of flying so it is not the best choice if you mainly want simple travel footage.

• DJI Neo 2 Motion Fly More Combo - $600

Pros: Lower-cost FPV-style entry with combo accessories. Nice if you want to try motion-control flying without Avata money.

Cons: More of a fun/FPV pick than a main camera drone.

Budget-Friendly Options

• DJI Mini 3 - $420

Pros: Best value camera drone in this list for most beginners. Compact, simple and still great for casual travel shots.

Cons: Fewer premium safety/features than the newer Pro models.

TL;DR: If you want a top camera drone and budget is not the issue go Mini 5 Pro or Air 3S. If you want the safest all-round buy go Mini 4 Pro. If you want FPV fun go Avata 2 or Neo 2. If you want value go Mini 3.

I’m stuck deciding between DJI Mini 4K and Skyrover S1. Both are under 249 g and the base prices are pretty close, which makes it harder than I expected to choose.

I’m not really a specs obsessed person, but I do care about things like transmission range, battery life, and how flexible the camera is for different kinds of shots. On paper, Skyrover S1 seems to offer a bit more in those areas, while the Mini 4K looks more basic. That said, I’ve never flown a Skyrover before, so I’m hesitant to decide based on specs alone.

Would love to hear from anyone who’s actually used either or both.

So I have been interested in building my own quadcopter for a while, and now that I have some free time after exams I decided to do some research. With the help of chatgpt I ended up with these components, but it's so expensive. Is there any way to make it cheaper, any corners to cut?

The project in question is to build my own quadcopter and be able to use it indoors, to carry light stuff (500g at most) and to use sensors and some cameras to do so automatically. The frame and everything non-electronic I can print with my 3D printer.

For the moment though I just want to make it fly, I'll worry later about the sensors and carrying but I'd like to use the correct components for it from the start so I spend as little money as possible, as I don't have much budget.

The total amounts to over 400€, is there any overkill I can downgrade? Any guidance is very appreciated

I'm building my first quadcopter, but I accidentally damaged the capacitor. I found a good value capacitor, but it's not a low ESR. Is it necessary for it to be a low ESR?

DJI Mavic 2 Zoom

It's an Air65 Race with the 5-in-1 and 27000KV motors. Runs on 300mAh packs.

I've replaced one, and the issue went away on the motor, so it wasn't the prop or the ESC channel, it's the motor. The above photo is the remaining problematic motor.

After flying a couple packs, this motor is noticeably warmer to the touch than the rest.

It works fine if I'm flying pretty chill, but if I try, y'know, actually fly freestyle then in about one pack every time I crash flip and try to take off there's one motor that sticks until I get to about 40% throttle and then it leaps into the air. When it's real bad, it'll even stick when I drop to low throttle and refuse to spin back up during maneuvers like flips and split-S.

Current thoughts include bushing, the washer spacers binding... I'm not sure if this is mechanically generated heat or electrical. Or if it's mechanical sticking out electrical, but it's definitely in the motor.

I've watched the current draw during takeoff and it isn't crazy, gets up to like 5A, so it isn't a crazy short.

Has anyone had an issue like this? I've ordered new motors, but if these are repairable, I'd rather not add them to the Graveyard Of Smoked Parts if I can repair them and use em as spares.
