RE: *Skyshark Edge 540*
Zippi, I have built one of there kits and am in the middle of a second one from them. I can tell you first hand that there quality is A+ and they take a great interest in Customer Saticfaction. If the edge 540 is anything like there kits the quility will be heads and toes above everybody else. They test there products thoroughly before they release them on the market as well. If you like there planes I would not hesitate to Buy one. I think they are well worth the money. Very well engineered as well.
