I’ve seen the HB F-16 and the F-15E at my club meeting a couple of months back. The F-16 seemed to be a cross copy of both the Revell and Hasegawa kits. Some areas were quite obvious when compared. The detail was so-so, but it was the grossly over-scaled panel lines which ended up being the major turn off for everyone. In this scale, these are way too heavy and soft.
The overall consensus was "Stick with the much better Revell F-16s", especially when the price is factored.
The HB F-15 was faired much worse and with a US retail of $25, it's quite the rip off for what comes in the box. Steer clear of the HB F-15s; they are just not worth it.
