Eh, those didn't bother me, since you can't see them from the outside anyway. At least I don't think you can see them.. lol. Now that it's built, it's perched on the top shelf in my theater room.
Haha, well, different people will be bothered to different levels (or not at all) by them yeah. I looked over some reviews/the instructions and determined that I'd want to replace these. Also lighting will likely make a difference too, compared to well lit reviews or flat instructions.
-The red/orange bulbs are all over the wing mechanism and super visible to me. This was really the catalyst for it all and I figured if I'm replacing these and going from the ground up might as well go whole hog =P
-The yellow bricks are in the tail and cockpit and visible depending on the angle or if the cockpit is open
-The yellow axles are in the wing connections and visible through the slits of other pieces
-The long red axles go through the body and aren't always well covered/hidden
-The long blue pins and short red axles are used everywhere and not always visible but there's so many of them I wasn't going to figure them out individually and just replaced them all
-The gray... technic... things... are for the wing connections and just clashed there for me so I made them black
