I just received my Mengnut Ming kit. Its definitely WNW quality in the detail dept for an injection molded kit. The fragile wing part is just hanging on by a few threads. I don't care - I've glued pieces back together before. The wing tapes are very small - narrow with just tiny circular dots - not rib stitches. They do protrude up from the wing surface a fair amount. No sink marks that I have found yet. Some parts and rigging points are labeled (molded into the plastic) 'DR1' or 'F1' for the different variations. Control horns are molded into the elevators but separate on the other flying surfaces. The PE pieces have molded plastic alternative pieces. The instructions are very WNW-like but maybe not as thorough and detailed (who looks at the instructions anyway?).
Overall, an excellent kit.
I think most complaints I've heard about are from nitpicking whiners.
My biggest gripe - its not molded in bright red plastic!
Guess I'll have to paint it.
