I have got TMOTOR VELOX F7 SE flight controller, TBS VTX AND camara : https://robu.in/product/1-3-cmos-1500tvl-mini-fpv-camera-2-1mm-lens-pal-ntsc-with-osd/

VTX is powered directly through lipo, camara is powered by VTX. VTX also have wire to receive video for camara but, i have chosen to send camara video through FC.

Everything runs smoothly for 2 mins, then FC is getting heated, motors individually get fired in random, tx is not working and red light on FC is constantly on, is unable to connect to betaflight.

Everything is running fine again when video is not running through FC. And direct conneted to VTX.

I need osd, camara was delivered with a osd board which has a botton and things labelled 14k, 20k and 30k

How to stream video with osd and solve this issue?

I have a TMOTOR VELOX F7 SE, and Use Betaflight as a Firmware, how to output IMU Data from flight controller via UART to USB, so i can connect USB to RasPi and access that data. And Possibly use that data for SLAM. How to do that?

Built a quad today using the SpeedyBee f405 v4 stack, plugged in a battery with a smoke stopper, beeped all 5 times, everything seemed good. Then I go into BlHeli Suite and it only detects esc 1, esc 2, 3 and 4 do not show up, what is going on?

Hi there,

This post is a copy of a topic I created on r/fpv.

I've been building my first 5'' quad, with all the ups and downs that this experience has. I am very glad to be able to build it myself, I'm learning so much on how the whole setup works. My setup is composed of a Source One V5 frame, Speedybee F405 V4 55A stack, Speedybee TX800, analog camera Caddx Rattel 2, Radiomaster ELRS RX, and motors Velox V2207 V3 1950KV.

After soldering allt the components, everything seemed to be working fine. FC and ESC are talking, RX and VTX do their job, all set in Betaflight and ready for a first test. But I encountered a problem that I am stuck with so far: when I connect my goggles (Eachine EV800D) to the quad, the only think I get is a blackscreen... and no OSD.

I've read many things on the subject while troubleshooting this. I know that it probably means my OSD chip is dead. But still, I had to try something. Here is what I did so far:

• cleaning the board of any possible solder that could create a short. No change.
• checking the power to the camera and VTX: all good. I even get a signal, the screen goes black when I plug the battery, which means the VTX is transmitting, I just don't get anything else...
• checking the video wire (both camera and VTX): all good. When I solder video wires from camera to VTX (without using the FC), I get a video signal in the goggles. So camera is working, VTX too.
• checking the settings in Betaflight: I noticed that when I flashed the firmware, I had OSD(HD) and OSD(SD) options at the same time. By default, the OSD_displayport_device was set to MSP (digital if I understood well...). So I flashed it again, even to an older version (4.5.1 or 4.4.3) with only the OSD(SD) option. No matter what combination I try (with vcd_video_system set to either AUTO, PAL or NTSC, and osd_displayport_device set to MAX7456), all I get is a blackscreen and no OSD.
• I tried to put as much osd options as I could on the display settings, to check if anything would pop up at the edge of the screen: no results.
• I can't find any visible damage on the AT7456E OSD chip, so maybe I'm just missing it or the OSD is just dead without any obvious sign.

I have no idea what options are left from here, except buying a new FC. I'm afraid I might just end up with the same situation. If any of you have ever encountered the same situation, and found a solution, please let me know! It might even help others that would be stuck with the same problem.

I sent an email to Speedybee, so if they answer with anything I will let you know. In the meantime, if you have any suggestion, I'm desperate to try it.

I provide the picture of my soldering on the FC. Please be gentle, I'm a beginner and I will definitely improve that in the future as well.

Thank you all, and thanks again for sharing your best and worse fpv experiences with us beginners.

Stupid build Ideas are welcome but i'll do all of them. Im the best with betaflight analog builds. Idea suggestions like 7" sub250 or pocket sized 3" would be the most interesting I think

I am looking to buy CS20
https://robu.in/product/cs20-dual-resolution-3d-tof-solid-state-lidar-5v-5m/

Purpose, is to place it on UAV and Scan things, i am not looking for long range. Scan Something like a building. Iam planing to use SLAM on ROS in ras pi Ubantu. I am looking to combine lidar and photogrammetry data., to create models. Out of all the lidars i find this seems to fit my needs. Now i have few questions.

1. I believe this doesn't out put in Color, what can i do to make my 3d models in color, Other then photogrammery; If i put a camara on it can i integrate it with this devise in ROS.

2. i know this is not Suitable for outdoor scanning, if not this, which lidar would you suggest. budget is 260 usd.

3. Is there a way in ROS to run Image/video SLAM and lidar SLAM simultaneously.

4. Can a raspberry pi with 4Gb RAM, handle both lidar and photogrammetry simultaneously, if it can't what other microprocessor can i use.

Thank you very for you patience in answering this, this project is crucial to me.

ETA - TLDR: Radiomaster Boxer switches SA & SB not being recognised.

Hey guys, so I crashed my drone into a wet grass patch with a bit of mud, dismantled it, used a blow dryer, left it to dry in a box full of silica gel for over 6 hours before I connected it to Beta flight. First issue | noticed was that the receiver wasn't receiving properly, and I replaced it. But even now, the receiver isn't working fine. Apart from AETR, switches SC, SD, SE & SF are being recognised by the drone but SA & SB arent, even though I set them up on the Boxer Mixes and Inputs. I had the SA & SB issue with my old receiver as well. But whenever I use switches SA & SB, the radio recignises it, shows switch position and everything. I even made a new Model on the Boxer, not working. I have a feeling this might be a software issue, flashed firmware on the FC, still the same issue. Please help.

Specs - FC- Flywoo Goku F722 V2 Pro Rx - Radiomaster R81 Tx - Radiomaster Boxer 4in1

Hey guys, we are currently working on an air quality measurement drone. Our drone is the DJI S900. We want to get rid of the camera gimbal and build a custom platform underneath the drone instead. On this platform we want to mount the measuring modules. Of course we have to design the platform by ourself.

Since we need to design this platform ourselves, does anyone have experience with a similar project or is there anything about this on the internet? Maybe there are any purchasable solutions we could look into?

Any advice or suggestions would be greatly appreciated!

I am building my first drone. Everything went well until now. I don't know how to connect my radio receiver with the transmitter. I have a Jhemcu ELRS 915 MHz and a BetaFPV LiteRadio 2 SE FrSky. Are the two compatible? If they are, how do I set it up?

Thank you in advance :)

When starting my quadcopter with equal divided weight it always rolls to the left when arming and go hovering. Betaflight motor direction and props are like the documentation tested and correct. Even re-calibrated the drone. And seems exactly moves exactly like the 3d example from betaflight to check the gyro.

Anyone have some tips?

I'm currently building my first quad. I have DJI v2 goggles and the fpv controller and would like to use...because I have it already. How should I wire this flight controller?

Betaflight F4 V3S Plus FC Flight Controller

Because I know you're all gonna ask, the jj abrams star trek-esque lens flare was actually unintentional and no, it doesn't actually exist on the real drone. My lens was probably dirty. Maybe that was jj's problem and he just likes making lemonade. Sadly the world may never know. #wokeuplikethis.

Hello people, I got a Radiomaster Boxer 4in1 a couple of weeks ago, been flying on sims and now I'm building a drone. I wanna know if I can use the Radiomaster R81 receiver on the drone or should I just get an ELRS module for the Boxer? Also, does the Happymodel ELRS ES900TX module work with the Boxer? If not, please suggest alternatives, Radiomaster Ranger isn't available in India as far as I know. Thanks in advance

I'm flying a Nazgul Evoque F6 V2 analog with a IFLIGHT Racecam R1 Mini for camera. Unfortunately my lens fall during flight and now i can't seem to find a new one.

So how should I replace the camera ? Do I need to buy the same one (which is no longer sold on the official site) or buy the new one the "RaceCam Mini Night Version" ?

And if I buy the new one which modifications should I do to get it working ?

After flashing my tmotor velox f7 SE with TMOTORF7V2, as there is no direct target, this is the closest i found. selected Quad 7inch propellers, for my 7 inch build. and its taking forever to setup settings. and i closed that box, now in cli with diff command. i get the following data Entering CLI Mode, type 'exit' to return, or 'help'

i have flashed Tmotor Velox f722 SE with TMOTORF7V Version 7.1.2, as there is no direct target for my FC. and motor 3 is not working on dshot300. I have changed all kind of settings. Flashed with different f722 boards. but same issue. there is nothing wrong with wiring, ESC and motor. as all motors are working in betaflight with dshot 600. the following are my mixer tab.

Hi
after satellite lock my GPS changes home positon constantly, both distance and home arrow go crazy. I`m aware that it can be connected with non-calibrated magnetometer, but mine is turned off.

Googles video feed:

https://www.youtube.com/watch?v=5_vJnQMvjOs

M10Q-5883

Kakute H7 v1.3

Betaflight 4.5 (same issue on 4.4)

Magnetometer is disabled. I could enable/disable on BF 4.4, after upgrading to 4.5 it can`t be enabled (weird).

All of the wires are ok.

UBLOX/auto config. Turning Galileo and Ground Assistance doesn`t affect the issue.

Any advice would be appreciated.

To me my motors sound weird. Especially when I go back and forth and make turns which I tried to simulate. The motors and screws also get insanely hot even after this short flight. No the screws aren’t touching the coils. I’ve already burnt one set of motors up on this build. I followed a nurk build video from a few years ago.

I'm torn between 5'' 6'' and max but wouldn't touch a 7 inch as a beginner.

Don't wanna go for 6S lipo, a 3 or 4 is alright, might diy something eventually (or use li ion)

Mainly I'm not looking for brand recommendations, just the kv and prop combo from some experts

I'm planning to build a cheap micro drone to get started. I'm a complete beginner at this looking to start somewhere. Did a bit of research on rc and arduino circuits.

My plan is to run a code that manipulates the power of all 4 motors from the signal of two X and Y axis joysticks from another Arduino nano transmitter I will make.

These are some questions I like to get clarified:

1. Can I use an Arduino nano to power AND control 4 small sized brushed DC motors?

2. Can an Arduino nano fully power each motor, enough for it to fly?

3. Can an Arduino do it alone or do I need some other sensors? I'm trying to keep the weight low in my drone and my wallet.

4. If an Arduino can't do it, what should I use to control the 4 motors?

Is this a viable idea or am I going wrong somewhere. Again, I'm a beginner so any advice will be greatly appreciated. Thanks a lot for any help.
