Quanum Pico Controller, (Spektrum)

I have this bound to a DX9, red LED on constant.

I have blue LED switching off for Maual Rate, on for Angle and Horizon

I have the green LED Flashing slow on power up, then three fast flashes, then off.

If I tip the board the Green LED flashes as expected.

BUT, I cannot get the green LED on steady which I assume means I cannot arm the board. No motors run.

Can someone with this board take me through the steps to set up arming please?

I have mine (Scisky, but same controller) bound to my DX8.

In cleanflight, minimum throttle is set to 1100, minimum command is set to 1000.

On my DX8 I have throttle travel set to 125% (both directions). These settings allow me to arm via the left (throttle/yaw) stick - I don't use a switch.

Thanks, the cleanflight settings are the default and what I had, but I'd not increased the throttle travel enough. Have just set 140% both ways and it now binds (I have it on a switch)
