like all the Witty Su-27's (no I don't have the number memorized, I looked it up ) it suffers from a poorly shaped nose, which is too blunt and doesn't angle down enough. The rest of the tooling is ok but not great. However their Su-30 is quite a nice tooling. If you want a PLAAF Su-27 there are a variety on Ebay sold by chinese sellers. They are usually listed as J-11 (the PLAAF designation for their copy of the Su-27) and are made by Terebo (AirForceOne). These are quite well done for the most part and have a much more correct looking nose. They all have fixed down undercarriage however.
