This is so cool!

My Dad and brothers are radio controlled aircraft fans from way back. They’ve been building and flying them since what seems like forever. As the technology has changed they’ve kept up. Along came helicopters – they were in. New engines, new battery types, new aircraft types – they’ve got ‘em all. Nowdays they have the cutest little wee helicopters that they can fly indoors – they buzz like bees. So cute. And then. Then there is this.
