Thanks for the comments guys! I really don't want to spoil the lines of the Ta 152 with an open hatch, especially at the front of the plane. And I didn't go all out on the engine... just painted it. So I'm gonna feel bad hiding it hiding it if I have to. If the cowling panel(s) fit well enough to stay in place, I might consider leaving them as snap fit pieces. But we'll have to see.
ON with the build... the engine assembly is attached to the cockpit assembly via four points on the engine bearing frame. The fit was spot-on... very impressive given the skinny nature of the frames and the distance between the engine connection point and the cockpit bulkhead connection. The four locating holes in the fuselage side are for interior detail pieces that end in the space behind the seat. These details, like the fuel tanks under and behind the seat, would be fully enclosed by construction with no change of being seen.
I carefully mated the combined engine/cockpit into the port fuselage side. There are no location pins but the fit, again, is great with all of the edges of the cockpit making positive contact with the fuselage interior. A solid bond can be achieved by running Tamiya Extra Thin cement along the areas of contact, which are many because of the all of the bulkheads. As you can see, I've left off the fuel tanks from the empty area underneath the cockpit.
The starboard fuselage side is then attached. Fit is almost perfect without having to force anything.
The fuselage bottom is another great fit. Seeing a pattern here guys? I definitely am! This ZM kit has been very nice to work with and my previous concerns seem to be unfounded. I'm not sure what happened with the build at Britmodeller.com that I have been referencing but I have had the complete opposite experience.
There is more interior detail within the tail assembly that I am leaving out. The tail access hatch is glued shut. The interior will be painted NMF.
I'm going to jump over to the next major assembly... the wings. The long, high-aspect ratio wings are a unique and characteristic feature of the Ta 152 and ZM devotes a multiple pieces and steps to build up the wing assembly. The foundation of the wing assembly is provided by a large yet delicate looking central spar. The bottom wing panels, left and right, are glued into place. Because of the delicate nature of the parts involved and that fact that there are no locating pins, one initially assumes problems with fit. But if you carefully refer to the instructions in terms of connection areas, you'll find an exact and precise fit.
The upper wings are modular too. I understand the separation of the gun hatches but am puzzled by the separate leading edge.
No matter... the fit is great so the modular construction isn't an issue.
I'm pausing the assembly of the wings here to do some painting. There is some nice detail on the central portion of the wing spar that will be visible through the wheel wells. I'm planning on painting the interior of the wheel wells an aluminum color... is that correct?
