Some progress on this build.
I decided to open up the underside nose vent and then glue a piece of PE in place using a mixture of CA / dental acrylic powder.
The end result.
I wasn't satisfied with the fit of the avionics bay door as it sat a bit proud and didn't quite match the curvature of the fuselage. In order to get a perfect fit, I glued a piece of stainless steel wire in place to slightly widen the rear, and then reinforced it with CA / dental acrylic powder mix.
The rear cockpit area was detailed using brass wire.
To ensure a proper alignment of the pitot tube, the nose cone was first placed on a flat surface, the W&D Studio stainless steel pitot tube was glued in place using 5-min epoxy, and then adjusted the alignment using a square as it was curing. The final step was to blend the pitot tube into the nose cone using CA.
Thanks for looking in.
