I fixed the problem with the nose section . Part 6a in the top pic shows a shaded area which tells you to paint the underside center strip olive drab but it also appears thats where the problem is . I removed the clear bottom nose section [part 14c] and filed down the underside center strip [6a] . This seemed to fix the gap as when I glued both nose pieces back onto the fuselage the gap was gone . I'm still not sure if this is a fault with the kit or something else I did wrong ? .
Anyway it's fixed now and I'm happy , I have three more of these little Helo's in the stash , I was going to build two for the U.S.Army and two for the Israeli IDF/AF . However one of my reference IDF books only mentions the Israeli's using the OH-58A version , so I guess all four will be U.S.Army birds .
Kind regards John.
