Gatwick miniatures models 1/144 complete kit resin + white metal for undercarriage

*especialmente interesantes para modelistas argentinos debido al set de
calcas de  estupenda calidad para armar un F-28 de Aerolineas Argentinas.

El unico modelo plastico existente del Fokker es el F-100 de Revell en escala 1/144, este modelo puede ser modificado a un  F-28 MK1000 sín mucha dificultad. A continuación puede verse una foto de un F-100  antes y despues de ser cortado, pegado y pulido, tambien pueden apreciarse el ala en su estado original y despues de haber sido reducida al tamaño adecuado, un set de  motores en resina representando los Rolls Royce spey pueden ser comprados o transformados para completar la conversión de este modelo.

The only plastic kit available is the Revell Fokker 100, nevertheless it can be easily modified to a MK1000. The
picture belows shows a F-100 fuselage and wing  before and after being modified to a MK1000 dimentions following the intructions stated in the bottom. A resin replacement of the engines is also available to make the conversion easier.

Wing modifications:
This is probably the easiest thing to do. From the 1/144 Revell F100:
for a F70: no modification;
for a -3000, -4000, -5000, -6000 wing: remove 0.49", 10.4 mm from each wingtip;
for a -1000, -1000C, -2000: remove 0.62", 15.6 mm from each wingtip.
for all F28s, add a leading edge wing fence half way between the fuselage and the first trailing edge fairing. On the F70 and F100, the wing fence is shifted in front of the first trailing edge fairing and looks smaller than on the F70 / F100 - beware, it is missing on the Revell kit!
The shape of the wingtips of the F28 is different from the F70/F100: they are more rounded. Also the wingchord the F70/F100 is slightly bigger as larger leading edges are fitted.

Stabilizer modifications:
Looks like on a F28 the sabs are shorter than on the F70/F100. Cut them all the way to the outer edge of the elevators - OK, this is my own eyeballing, right  The shape of the stabilizertips of the F28 is different from the F70/F100: they are more rounded of.
 

From the 1/144 Revell F100:

For a F70: remove 15 mm (5 windows) forward of the wing and 14.8 mm (almost 5 windows) aft of the wing. Out of the three cargo doors of the F100, the middle one is deleted on the F70 (just forward of the wing). The relative position of the forward cargo door with the nose seems to

change very shlightly (backwards) but I wouldn't worry at 1/144. Delete the forward over wing exit - but keep the window.

For a F28-2000, -4000, -6000: remove 24 mm (7 windows) forward of the wing and 17 mm (5 windows) aft of the wing.

For a F28-1000, -1000C, -3000, -5000: remove 31.5 mm (9 windows) forward of the wing and 23 mm (5 windows + the rear over wing exit and its extra spacing) aft of the wing. Delete the rear over wing exit. Where the deleted exit occupied the space of two normal windows, the two windows should be re-established. On the freighters, blank out windows 2 and 6 - this is where the cargo door edges are.

Engines:

RR Tays power the newer F70 and F100. The older F28 is powered by RR Speys, smaller in diameter.
A not too bad replacement for the original Revell Tays is a set of Airfix Caravelle RR Avons - cut their exhausts. Not quite the right thing but with a bit of work they should look fine.
