Wing cover TE U bracket fitted with an M2 threaded rod ‘U’ to provide scale-ish rear fixings (Wing cover should finish just short of the TE bracket, with 2 threaded rods attached to rear of bracket, with wing nuts used to tension the cover).
The model TE bracket clips over the wing TE and is tensioned by the 2 springs attached to the rear of the rear incidence rod former. This avoids having to fit small nuts during rigging, plus the paint is likely to stay on a bit longer.
The use of a small cup hook for forward attachment allows the arrangement to be removed if needed.

Meanwhile, the pilot seat back has been fitted, comprising of a small horizontal piece behind the seat pan & 2 upper side plates which extend to the fuselage side skins. (I’ve made all parts removeable in order to be able to get at the seat frame fixings)

- Seat rear plates
The model former locations are not quite as per the full size, so slots had to be cut in the seat upper side plates to allow these to reach the fuselage skins.
A picture of a full size arrangement shows the similarities, although I have omitted the additional slot for airbrake cables on the Port upper side plate. This photo shows a rectangular headrest, whilst VV400 sports a circular version.
At 1/3 scale, the headrest is a 50mm diameter domed cushion mounted on the front of a short 50mm diameter pillar, like the one shown.
