I don't know what possessed me, but for some reason I was trawling through the Parrot AR.Drone store.
Then they caught my attention. Some strange inflatable Dyson desk fan looking device called 'AR.Race Donut' and then I saw a couple of inflatable carrots! which happen to be the 'AR.Race Pylons'.

So looking into these a bit further and reading through the standard vague Parrot blurb I come to notice that these things are HUGE!
The donut is 1.8 meters high by 1.2 meters wide, the pylon is 2.5 meters high with a maximum diameter of 40 centimeters.
Too add the pylons are also the start/finish line, with a width of 39 centimeters and 1.96 meters long.
So I was sat there thinking, ok it's a race, but you don't need any skills for hurling your £300/$300 AR.Drone between pole just short of 2 meters or trying to fly through a hoop 1.2 meters. The AR.Drone is approximately 52 centimeters wide, the donut's inner hoop is going to be about 30 centimeters wider than the AR.Drone at it's widest part. My lounge door is narrower than the hoop center and I can get through that flat out without any sweat.
But.....
Then it dawned on me, these things are tall, the donut is just a few centimeters shorter than myself where as the pylon is massively tall. Taller than most peoples rooms in their house. These are for outside use(unless you have a warehouse) and outside is windy. Not that could make things more interesting and challenging.
So then, your flying outside, without the indoor hull, all four rotors happily spinning away, you can imagine it, a sudden gust of wind, and you chop/slice the inflatable object, but alas Parrot have been kind enough to supply a puncture repair kit. So back are the days of the old bicycle with a flat. Woo hoo Thank you Parrot for supplying a repair kit and also a very well needed carry bag for the AR.Race inflatables.

So what else do these do? Well apparently the weighted based AR.Race inflatables have colour coded stripes, the donut for lap times and the pylons for start and finish lines. No need for stop watches then, which is a smooth move.
If that wasn't enough, Parrot have also disclosed that AR.Race is for a maximum of four players.
So far your probably now thinking, okay great, but I haven't told you the price! The donut is $49.99/£39.99 and the pylon is $59.99/£49.99. That's $110/£90 for a set to even start to have a race.
I'll let you decide if you think that's a reasonable price but I'll be printing out my 'finish' line and 'laptime' lines thanks.
