Anybody know anything about them?

Is it just me or do you find the website a little confusing??

Oh, very. Hard to communicate with them. I have been chatting with their agent, Bobby Sin, in Hong Kong, he's an interesting guy, most definitely a fellow modeller.
He said that some Middle Eastern guys ordered twenty turbine models, all ready to go, for $30k each, all at once!
I beleive the three models for turbine they have are the SU-37 (the forward swept thingie), the Mig 29, and the L-1011, prices are (approximately) $4000. Contact them for further details, I don't know a lot about it.
The ones that really interest ME are the 15 sized models, you guys know I am a sucker for that oddball stuff, and I am trying to get my hands on some...

Man, you did a lot better than me! I couldn't even find those pictures that you have posted! I didn't see any of the .15 size stuff on their site.
The SU 37 is a cool plane but the pic on the website really doesn't show us much. Actually none of the pics really do.
I did send them a note on their onlineform though.
