I found I didn't like the square ends of the fingers so I added small pieces of Evergreen half-round stock to the end of each finger to round them off.
The arms on the Special Forces TIE (bottom) are shorter than the standard FO TIE (top) to account for the hyperdrive cogs on the SF TIE, but the Whisper needs the normal length arms as it doesn't have the cogs.
New extended arms glued in place. The separate brace pieces above and below each arm strengthen the joins and make sure everything is positioned correctly
The front red part of the SF TIE is a slightly different shape to the other side but on the Whisper the two sides are symmetrical. Therefore this piece needs modification by thinning the parts shaded in black.
The conversion kit canopy is not glazed (and has different proportions to the standard kit part). Therefore I cut up one of the conversion kit parts (right) and used parts of it to modify a kit part (left). The new canopy will be used as a master to mould new ones.
Hull extensions seen from the front - I also had to notch the top right unit to fit the aerial mount. The extensions still need some filling on the joints to the original hull.
Gaps under the extensions filled with Aves and a coat of interior grey on the transparencies - also used it as a primer to check the filled areas, same as for the interceptor version.
Used the Micro-Mark Photo-Etch system to make 72+ brackets which will go on the wings. Lots of learnings from making these as its the first time I've done anything like this
Finally getting around to the wing brackets - drilling the holes (used a small steel rule and scriber to mark the locations for 4 1mm holes per bracket)
This is a conversion of the Bandai TIE Special Forces fighter into the standard TIE Whisper from The Return of Skywalker (although I'm not sure it got much if any screen time). It needs some minor mods to the wings, some major changes to the wing mounts and some extra 3D printed parts for the fuselage ball.
