Servo Output No Movement on Setup

Hi Everyone,
Newbie here. I have connected my Orange Cube, downloaded the recent Arduplane version. I can have completed the set up. The Herelink3 is showing GPS, ADSB is showing traffic, the V Tail set up correctly on Radiomaster 16s. I went into the servo display and theres no movement on the graphic. The throttle does not work either. Please can someone help me get it working.

Also. If there is anyone near London who is an expert and can spare some free time, I would kindly offer some cash to come and help.

Kind Regards

Chris (London)
