Thanks Matt and Wojtek.
The window frame and other unwanted mouldings have new been removed, and work has started on the detail for the cockpit roof.
PIC 1. The window frame removed and the aperture enlarged, with the correct shape at the lower forward edge. A thin upper frame has been added from stretched sprue, which will fit onto the base of the cockpit roof transparency, and the wind deflector, on the forward pillar, has been added, also from stretched sprue. This will be sanded when fully set, to blend the angles, and remove the scratch marks on the fuselage sides. The bottom hole for the large hand hold provided in the kit has been filled, and awaits sanding. A smaller hand hold will be made and fitted much later, and also a similar handle at the base of the forward edge of the window. The window slide rail has been added, and will be sanded 'flat' once fully set.
PICS 2 and 3. The windscreen transparency has been masked inside and out, to protect it whilst fitting the exterior and internal detail.
PIC 4. The fairing over the upper front panel has been added from plastic card, and will be sanded to shape once set. On this Mark of Wessex, after avionics updates, the Perspex central panel in the roof was replaced by alloy panels, with the 'bulge' at the front.
PIC 5. The bases for the roof switch panels have been added, along with the rotor clutch cylinder and lever, and will be detailed with switches, radio leads etc later. The transparency will then be re-masked, and the internal frames painted matt black. The exterior will be masked also, ready for painting later, and the part fitted to the cockpit, along with the port window, in the closed position. (The starboard window aperture will be masked, and the window fitted, in the open position, near the end of the build.)
Thanks again for your interest and compliments, and I'll post another up-date soon.
