Hey everyone, I'm having trouble with my BetaFPV Air75. The U.FL antenna connector keeps slipping off the board. It works well when I press it down, but it doesn't stay secure enough to fly. What’s the best way to secure the U.FL connector without damaging the VTX?
I’m wondering cause I kind broke my camera also is there a way I can just get a new one or should I just buy a new drone
caught some better shots last night, will do a nice edit later
Complete beginner, never flown anything. Spent a full day researching with some AI help and landed here. My priorities are longevity, minimal upgrades, and compatibility with bigger drones and maybe RC cars/planes down the line.
Everything is locked in except the drone.

Option A — Happymodel Mobula7 1S ELRS
> Most proven, biggest community, no FC surprises reported.
Option B — BetaFPV Air75 Original 5IN1 ELRS
> Lighter, recommended by creators I watched, seems well loved by the community.
Option C — BetaFPV Air75 II Freestyle ELRS
> Newest frame, supposedly 80% tougher after crashes. Some FC issue reports made me nervous though.
Leaning toward Option B but genuinely don't know what I don't know.
> Willing to change anything, I just want to get it right the first time so I'm not buying things twice.
Hi everyone, I’m new to FPV and I’m having a serious issue with my BETAFPV Air75 II Champion.
The quad started having vibrations, and while trying to fix it I accidentally reset all the settings in Betaflight. Since then, I’ve been stuck trying to recover it.
Now I’m running into multiple problems:
The CLI dumps/presets from the BETAFPV website don’t work on my version (I get “unknown command” errors)
The VTX seems inconsistent (on USB I only see OSD, and video behavior is strange)
When I arm the quad, it immediately shoots straight upward uncontrollably
The drone is an air 75 II champion btw and I can see the osd but nothing is there other than that I did just see the vtx antenna came loose because of a crash but how do I fix this after that I tried with a preset I found but still doesn’t work what’s wrong
Overall settings seem completely wrong after the reset
I’m still a beginner and I’m not sure what I messed up or how to properly restore it. I’m worried I’ve broken something in the configuration.
If anyone has a BETAFPV Air75 II Champion (especially stock or close to stock), could you please share your Betaflight CLI dump or correct factory settings? Also any advice on how to properly restore it on newer Betaflight versions would really help.
Thanks a lot in advance.
Gonna start this off by saying I have owned the Emax transporters (I use the screen on the bench.),VR03s, Vr02 and my daily driver is the skyzone 04x, while I prefer my skyzones I have never minded box goggles; and was debating getting the HDzero box pros.
The meteor 75p1 is snappy, but you can notice the difference if you fly both systems back to back, it flys like a meteor and I love it; no complaints with the quad.
I love the p1 system and the visuals are super good and I don’t notice the latency; the connection to bind is super simple and the menus are easy to navigate. The price is awesome and I honestly think it will be a great introductory system to digital FPV.
Now for the negatives, the goggles are painful on the face, the light leak is awful, worse than any other box goggles have owned or used. The rubber nose piece obstructs view and is painful on my nose; and my nose is average. The weight is noticeable and doesn’t sit comfortably.
My analogy for the whole thing is it’s like chocolate, you are super excited to eat it and then you find out it’s bakers chocolate.
Wait for a VRX or an alternative goggle to release, I also would avoid getting them as an intro analog goggle. Go with something nicer, even the VR03s fit better and felt better.
This would be my first drone, I researched about it and a lot of ppl seems to agree that a whoop should be your first drone. Also I live in red zone so I would have to travel for 30min just to fly a 5 inch so a tiny whoop is the best bet for me.
I have soldered 4 in 1 escs and esp32 and sensors before but nothing as tiny as a FC for a whoop. So I thought going with a BNF is a good Idea( if you think I should build my own Whoop pls suggest a parts list, Thx) , for the BNF I wanted to go with the Air 75 II instead of the Meteor 75 as the Air is newer. I will probably cap the throttle to 80% or 70% and increase it as I go.
What are your thoughts on my decision ??
One motor twitching when armed on air75 ii, when disarming and arming again, it flies normally again. This is my first tinywhoop, I haven't had any problems or crazy crashes into hard surfaces yet. Any help is appreciated :)
PS: I have also noticed a kind of rubbery smell coming from the FC (?), not particularly a burning smell but not one i've noticed before. Maybe i'm just being paranoid
2nd call for help in 1 day :/ Just noticed this front part of the canopy has broken and the screw is lost. Is it mandatory to replace the canopy?
Also it appears a piece of the camera plug is damaged, it doesn't look like cause for concern but wanted to make sure.
Also there I've noticed a lingering smell of rubber (kinda burnt). Yesterday I was flying and it started to rain slightly, I quickly flew to cover. Could there have been a short? Thank you :)
Battery life has tanked and the core temp is way too high.. not sure what to do. I’m only getting 2 min 50 sec with a 580mah. Used to get 4-5:30 cruising.
It is hot outside but it’s not that hot..
This weekend I am going to test these 2 builds.
The difference between them is that one has 7000kv motors and 3 inch biblade props.. And the other has 8000kv on 2.5 inch biblades.

Greetings to all ,
I am seeking constructive criticism of my solder joints quality.
I have used a T12 D12 chisel tip on hglrc rc2 soldering iron to solder all these and it was too big for the smallest pads.
I am sharing pictures of solder joints of firstly 3 really tiny pads for connection to 28awg wires of a nano fpv camera having 3 wires for video,5V and Ground.
Next i have soldered two 18awg wires connected to xt30 connector to the slightly bigger pads to power the board joints from a 2s lipo battery.
I have used a multimeter to ascertain There are no shorts anywhere and used a fancy fuse device or a smoke stopper to power and see the board's functioning without it smoking .

Is a solder point? Or is just dirty
