Hello, I purchased the same 4in1 esc. It took over a month to arrive from banggood. Now I cant find any info and instructions. Banggood seems to have removed the listing and ufofpv.com does not work. Did you get instructions on how to wire this esc?

Hi Rcnoob,

here you'll find the info: https://www.banggood.com/Blheli_32-4in-1-2-4S-Lipo-40A-ESC-Dshot1200-Ready-W-Current-Sensor-for-FPV-Racing-RC-Drone-p-1316340.html?rmmds=myorder&cur_warehouse=CN
If you scroll down you'll see the wiring instructions.

Greetz ;-)

Thanks for the info. I couldn't find that page. Looking forward to watching the rest of your build.

Have you got your gimbal motors yet?

Think I'm going to order from somewhere else in that case.

Just informed at the post office. Nobody knows where the package is. So the sender needs to ask for an inquiry at his shipping service... Curious what will come out of that. So I think I'll start off without the cam...

Past weekend I tested the drone (without props) to see if everything works in iNav and that the motors spin the right way. Everything works fine  ;)

Next things to do:
  • find the good connectors for the cables of the motors (I won't let them as on the picture; this was just to test)
  • make a good connection for the cables of the GPS (which seems to work in iNav even with an F3 controller)
  • make a good connection with 1K-resistor for the cables of the sonar
  • get the prop-file from Kananga and print it ;)

My bad, I'm repairing my printer today, I'll sort the adaptors for you.

No hurry Kananga! I'll start with the GPS and Sonar. Then I'll configure my LEDs. Printing won't be before the weekend.

OK, so GPS, sonar and LEDs working and configured! YES!


Next step was to check if I could connect the cam, but there I'm completely stuck...

The Foxeer Legend 2+ has 4 cables coming out (2 black, 1 yellow and 1 red) (https://www.banggood.com/Foxeer-Legend-2-F2_8-155-Degree-Wide-Angle-12MP-HD-WiFi-Camera-For-FPV-Racer-Drone-p-1053384.html?rmmds=myorder&ID=224&cur_warehouse=CN):
  • I suppose one ground (black)
  • one positive (red)
  • one video (yellow or black?)
  • and one audio (yellow or black?)

The FPV-transmitter (https://www.banggood.com/Eachine-VTX03-Super-Mini-5_8G-72CH-025mW50mw200mW-Switchable-FPV-Transmitter-p-1114206.html?rmmds=myorder&cur_warehouse=CN) has:
  • a pos & neg IN (towards my FC to get 5V I suppose?)
  • and a pos&neg&sign (yellow) OUT (towards the cam; just need to figure out which one on the cam is the video and which one the audio)


If I'm right I only need to connect those on the mavic and install the Go FPV-app of the FPV-receiver (https://www.banggood.com/Eachine-ROTG02-UVC-OTG-5_8G-150CH-Dual-Antenna-Audio-FPV-Receiver-for-Android-Tablet-Smartphone-p-1242422.html?rmmds=myorder&ID=224&cur_warehouse=CN). Is that right? But how do I connect the FPV-receiver to the FPV-transmitter? Only long pressing so it scans all frequencies?

No other connection to be made with the FC but the pos and neg of the FPV transmitter?

But I could also hook up via the foxeer-app directly and control the foxeer without all that if I'm not mistaken. That goes over Wifi. Just tried it, and it seems to work fine. Moreover, I can control when and where to take pictures and videos directly from my smartphone.

My FC (https://www.banggood.com/Upgrade-NAZE32-F3-Flight-Controller-Acro-6-DOF-Deluxe-10-DOF-for-Multirotor-Racing-p-1010232.html?rmmds=myorder&ID=17&cur_warehouse=CN) has no integrated OSD if I'm right (only connectors for it > 4 cables on UART1 > +,-,TX,RX). Or can I connect my camera directly to that OSD (grd,5V and TX or RX for video; no audio than??)?

Thanks for any help on this.

I don't think your Wi-Fi will have the range but I'm not very informed with Wi-Fi yet.

The rest of the questions I've an idea but I don't want to tell you the wrong thing, I'll have a look through your stuff and get back to you. I've got a simular transmitter (mines the one lower spec I think).

Yellow is normally always video, white is often audio.

As far as I'm aware the camera will go to the fc, the osd will go to the fc and the transmitter will go to the fc.

I'm considering not going through the fc with my camera, it's somthing that I can easily change at a later date with an extra wire. I'm just going to set the camera going before I take off.

Read up on what power your fc is happy to put out, you might be better going to the main power with your transmitter, I know some boards won't even run a receiver properly and are only designed to run leds and a buzzer.

You might get some suggestion through inav? For example if you go to the fpv section does it say which connections to use.

I'll have a quick read up for you and post back if I find anything, in the mean time someone else may know already and post up.

https://m.youtube.com/watch?v=qd4gl_udJKY  setting up your camera to your transmitter.

https://m.youtube.com/watch?v=wH14PK1cI3A  some fpv-osd-fc tips

http://www.multirotorguide.com/reviews/review-eachine-atx03-micro-transmitter-with-audio/  wiring up the vtx

When I tried my video receiver with a different fpv system I just long pressed so it started scanning just as you thought,  it soon picks up the signal.

I can't find a wiring diagram for the foxeer 2, I take it your wires don't have th3 plugs on.

Hello,

I'm trying to connect Omnibus f4 pro v2 controller.
I've connected Doha now
Frsky xm + - SBUS, 5v and GND
GPS BN-280 - UART6 - rx6, tx6, 5v and GND
Servo gimbal - pwm5 and pwm6
LED - on the other side of the J1 - 5V, GND and LED
This is bothering me now
Sonar HC -SR 04 - 5V, GND, (UART6 - SCL and SDA) if I understood it well

Hi Ursos,

I have an F3. Got the same sonar. just plugged in the IO_2 for the ground, 5V, trigger and echo. worked perfectly.
Wich gimbal controller and which motors do you use?

Small update:

Just put my mavic outside and ... YES: got a very quick 3D GPS fix!!

My motors seem to be lost somewhere on earth... Reseller sent them, the post got them, but I never didi. So an inquiry has to be started. First flytime will be without cam.

Now I need to buy some gold bullet connectors for my motors to connect (https://www.banggood.com/10X-2mm-Gold-Bullet-Banana-Connector-Plug-For-ESC-Battery-Motor-p-946666.html?rmmds=search&cur_warehouse=CN) and a Lipo charger. the one I bought is only to hook up on a car battery. Overlooked that...

Kananga, got the prop adapters sorted out? Don't hesitate to provide them.
How did you dismantle the original props from their connection?
