I have the GWH F-15E also, thinking it was going to be this awesome building experience for the price it was going for. Haven't done much more than cut all the parts off the sprues for the cockpit subassembly. Not very impressed with it so far. The more I see from Chinese manufacturers, the more I stay away from them.
I also have the Tamiya 1/32 F-15E that I'm in the middle of building. Definitely an old model that still holds its own against more modern manufacturing processes. One tip I can give on that one as a build pitfall is the ejection seats. They have these mounting stands on the bottom of them that are twice as high as they should be. If you don't shorten them, the canopy won't close. Its also a little dated, detail-wise, so I highly recommend aftermarket stuff for the cockpit to help dress it up. It has the basic quality structure though that makes modifications well worth it, with minimal effort.
I've been dressing my cockpit up with a hodge-podge of stuff from Quinta (lots of stuff on the seats), Eduard (Used parts of the Eduard cockpit kit for the instrument panel and side panels), and stuff I scratch-built. HAD to scratchbuild the throttles, because even the Tamiya throttles are kind of a joke.
