Neostrider No I haven't, like most people I dont check every posting made, despite being part of admin. This particular posting came to me via PM from Petrol himself to get a more honest opinion on the whole model. I kind of got the idea of what it was made of anyhow, but to justify this taking off I felt it needed to have longer, and perhaps more flexible blades like that of a gyrocopter. Many thanks for your heads up though, I'll look before I leap next time... Cheers Jay
