I know it's hardly motorsport but it does have an engine and you could race it so I guess it just about fits the rules.
Anyway... I went out with my Son yesterday, He's 31 but an overgrown kid at heart (just like the rest of us I guess), mostly he's into RC aircraft, but this time he wanted to try out a truck. It's absolutely mad. Two forward gears and reverse, runs off some kind of nitro mix and goes like stink!
Taken on the 1DIIn with a 200mm f/2.8. TV at 1/500, mostly around f/5.6 with AI servo. All probably cropped around 50% or so. I had a hell of a time just keeping it in the frame let alone thinking about nice composition. Great fun though! But I think I'll give the 300mm a try next time.
