i'm currently building a great planes super skybolt and while not ALL the parts are laser cut it does have it's share of blackened edges. i can't remember which ones are laser and which are die cut but i do know that they have some pieces laser cut.
Sig is very hard to build.
if you don't mind i'll have to disagreee with this, my first kit was a sig four star 60. went together perfectly and everything lined up correctly. every piece of this kit was laser cut. still flies great today. it was a great second plane and i'd suggest it to anyone, if for nothing else the easy ability to modify it. check some of the thread on the forums. if i have to rekit this one, i've already got a minimum of 6 mods chosen to incorporate into the build.
