The spinning-lawn-mower-of-death-360-DirtTV helmet cam makes it's World Cup debut at Fort William.

Kieran Mcavoy risked life and limb to ride the gizmo down the Fort William WC 4cross track during Saturday nights practise session before the main event.

Seemed to work okay for the first trial run.

Will he wear it in his heats? Will the DirtTV aeroplane fly overhead aswell?

Find out soon on DirtTV
