they simply follow Chinese business ethics and borrow someone Else's design/molds.
I thought of that. The FEJ one is enough bigger than the others that they couldn't simply splash the molds off an existing model. The point I wanted to make is that this is a small market. Only so many guys want a large F-18, so why do one that directly competes with five others already on the market. Theirs would probably be cheaper than the others, but it seems that market is already saturated.
It's not that difficult to copy someone else's design and scale it up or down. So while they are at it, instead of going a little bit bigger, why not go smaller where there is no competetion?
