Hi, I've got everything set up but transmitter input won't get motors spinning. Any ideas?

Hi,

This is my first quadcopter build.

I'm using a Flysky i6 transmitter and Flysky iA6B reciever in PPM mode.
I'm using an F4 V3 flight controller and 4in1 BLHeil32 35A esc.

When I move the control sticks on the transmitter, the movement is visible in betaflight.
When I use the software to power up the motors in betaflight, the spin up (using pwm motor protocol).

However, when I try to get the motors to spin up when I move the throttle on the transmitter, nothing happens.

Is there some kind of arming procedure I'm missing? If so I can't find it.

However, there is a small blue light on the flight controller which stops flashing when I hold the right stick on the transmitter to the bottom left corner for a few seconds. After that's done, it only begins flashing again when I move the throttle stick up. This leads me to believe that I have actually armed it.

Any help much appreciated.

Thanks

Update: I just got it working with PPM. Had to configure one of the switches on the transmitter to arm the drone. The sticks don't do anything to arm it. Thanks

I'm using same Tx. are you using ibus.
Best using arm on a switch as the stick arm is dangerous. If for some reason both sticks get to the disarm position while flying it's a dodo.
My arm is on aux5 - SWA switch.
