Yep, Grant hit it right on the head.
Making the IMEX/Kangnam kit into something accurate is VERY difficult and time consuming. If you're just looking to build something that looks like an Apache, it is ok, but if you're looking for an AH-64D, go with the Hasegawa 1:48th kit, it is by far the best out there.
The Kangnam/Imex D Model is WORTHLESS and TOTALLY INACURATE.
Ok, I've vented...
Whew...
