Ask anyone, they'll tell you. I'm "Mr GWS" around these here parts. I have, or have owned, almost every warbird out there (some more than once

), and am on the earlybird program where I'm able to get the newest models before they even hit the store shelves. I even own some of the non-warbirds like the Slow Stick, Pico Stick, C-130, DC-3, Tiger Moth. You get the idea.
Most people think of GWS as cheap foam planes that run on brushed motors and NiMH batteries. Well, times, they are a changin'! GWS now has a full line of brushless motors to compliment their new kits (but I still mostly use Scorpion motors

), and the kits themselves are designed around brushless power and lipos.
GWS has even started making a few kits out of EPO foam, which is basically the same type of foam Multiplex uses in most of their planes, called Elapor. It's that flexible stuff that doesn't break as easily as the regular EPP foam of the normal kits.
I am currently working on their two newest kits (both EDFs); the A-4 Skyhawk and the Chinese J-10 all-purpose fighter. And best of all, the foam keeps my lipos warm in the winter and cool in the summer! (not really, that bit was just for you Joe

)
If anyone has any questions about GWS, I'm your man!
