i have seen a few of those doing the rounds at Model Air Shows. they are Awesome but the blokes are proper Nerds. i used to fly mine in chessington, there was a bloke there, we called "arther English". he spent about 2 years building a fan jet Delta wing only to crash it on his maiden voyage! he was devo'd. i think he even cried!!
i have crashed my training plane, but at the moment i have a Wot 4, which is an awesome novice plane. fast, yet forgiving!
into Nitro car/buggy now as you can tale em anywhere and just use them
