On second thoughts, it looks slightly surreal. When the red one 'takes off' for the first time, it gets up one hell of a gradient, yet retains its speed. Looks maybe slightly suspicious. Meh, I still want one
Its gains such height so quickly due to it being very light, and having a high power/weight ratio engine. Found a few sites that sell the kits for ~$220, but I'm thinking I'll get the plans and make my own
And other people have got videos of this working to, so meh. I think its real.
