Overall, I think the general shape and size of the HB-4 is pretty good......not perfect but good. There are a couple of small things that stick out like the previously mentioned area on the fuselage above where the horizontal stabs attach. It has too much of a hump. That can be easily sanded to something closer to what it needs to be. Another area that I think is a little off is the spine hump and the angle of where it meets the tail fillet. It also seems a little off, again, nothing that some good photos and some sanding can't correct. I think if all kits were subject to some intense scrutiny
