PPM Motors & Controller Only Running AUX3 & AUX4

Hello,

I am building a quadcopter as part of a project in school. I am trying to configure it using Betaflight but am encountering some difficulties. The default ESC/Motor setting was Oneshot125 but I was having difficulties with that, so I switched it to PPM and so far I had all the motors turn on. Is there a way to confirm that that is the right setting for my motors? (using BLHeli Makerfire 12A ESC's, and EMAX 2204's)

My other, main problem is that when I move the left joystick on my controller (Flysky FS-i6, receiver Flysky FS-IA6 that came with the controller) - the only output I see through Betaflight is AUX3 and AUX4. I found this resource that might help me out, but I am not sure how to apply it.

I am currently away from home and did not bring the quadcopter (image below) - I do have the controller, receiver and flight controller with me. I am not getting light from the receiver, which makes me assume that the flight controller needs the battery connected to it (via BEC) in order to provide enough power to the receiver? I figured that micro USB might have been enough.

If I recall, Flysky channel mapping is different than others (maybe 1234AETR?)Here's a video that might help

Thank you. The video shows it as AETR1234 which is what the default setting is and it's not working.
The controller also has an output option for i-bus and it's set to channel 1. Not sure if that has anything to do with it. I also enabled PPM (which was off previously).

Is there a right connectivity into the receiver? It feels like there are many options here and it is hard to get everything to cooperate.

Thank you,

This one. Skyline F3. Flashed with SPRACINGF3 3.0.1 via BetaFlight (hopefully that's the right firmware for it :))

Let me know if I can provide you with any more information. I appreciate your help Renov8r.

From your receiver, you connect to + - RX (rx is signal wire) on either UART 2 0r 3 shown on bottom left or right of the board.

I'm not sure I follow. Initially, I thought I use the 8-pin connection only, and the other ones are for telemetry, which I don't have.
Here is the manual for the Emax F3 Aero.

And here is my current setup, along with the cables that came with the flight controller. I placed the 3-wire connection to channel 1, and then every following wire into the following channel.

As for the ESC's, I just checked their specs and apparently they support Oneshot125 - should I try running that again over PPM, via Betaflight?

Thank you,

Can I run the ESCs as PPM but have the controller talk to the receiver not in PPM ?
When I get a chance, I'll try Oneshot125 again and see if the motors run via USB connection that way. Still doesn't solve my receiver issues

I'm still uncertain about the channel settings as well. Is my wiring correct, and do you rhino it's a software issue ie channel mapping?

You need to watch the setup video a few more times. It's all there. One step at a time...............

My apologies, my memory played tricks on me. It was set to AETR1234 and that is not working.
What more, the video discusses running PPM, and Jackson is saying that my receiver (FS ia-6) is not compatible with PPM.

Also, I just realized that the ESC/motor configuration I'm running is PWM, not PPM. I will try to switch it to Oneshot125 nevertheless, but will only be able to do that on Sunday.

I am somewhat lost about this setup. Is there a way to know what settings to input for Betaflight from start to finish and then I can try adjusting the cables?
i.e. I'm currently running RX_Parallel_PWM on receiver mode - is this the right mode? And Spektrum2048 on the serial receiver provider, although I assume that doesn't matter since I'm not running the receiver in serial. I should switch this to SBUS regardless I think?

Thank you again for all of your help folks.

Don't worry about the details for now, lets just get you in the air. First, all ESCs are PWM, that's the type of signal that controls them (unless you're using DShot) and has nothing to do with receiver input.
Receiver mode - PWM is wrong, it needs to be SBus mode in your transmitter
Spektrum 2048 is wrong - needs to be set to SBus
Mode-needs to be set to RX_Serial for UART 2
OK, here's a video that shows in simple language EXACTLY how to set up and configure Betaflight using SBus.

I'd like to keep the receiver if possible, instead of buying a new one just yet. I'm assuming it should be working but we are just not getting the settings down right.
This is for a project in school and we are limited on time and budget (we need to be up and running for the showcase next Saturday).

I've attached some settings that might help us figure this out. From the flight controller manual. The wiring is currently in IO_2 but I can plug them to 1. It seems that I should only connect 4 of the 6 wire sets from the receiver to the flight controller or am I not getting that right?

Thank you,

OK, now I think I see where you're getting confused. That's the great thing about sBus, PPM, 1 signal wire carries all your channels so you're trying to connect waaaaaaaay too many wires. Yes, you need to connect to IO_1. 1, 2 and 3 are ground, power and PPM signal. Just connect them to the corresponding pins on channel 1 of your receiver (I'm just guessing that channel 1 of your receiver is PPM, some are channel 2)
