The Su-7 - in 1/48 scale - has one kit in town: the late 80s kit from Kopro/OEZ recently re-boxed by Eduard. The model is somewhat limited in surface detail and different manufactures offer ways to enhance it. Among them is Master Model which offers a drop-in replacement for the guns and pitot tubes (nose and wing).

As you can see in the pictures, the guns are a vast improvement over the originals, which are basically a plastic rod. The metal replacement parts have nice hollow ends and have different lengths to properly reproduce the placement of the guns in the Su-7.

The wing’s pitot tube has a much fine shape than the plastic one. Please note that you will have to keep the base of the plastic pitot tube and modify it to receive the turned brass one. Very simple to do with a file and a drill bit.

Perhaps the master piece of this aftermarket set is the nose pitot tube, with its combination brass/resin and the incredible detailed vanes (to provide angle-of-attack information to the pilot).

The resin part seems to have a bit of flexibility to it (i.e it is not brittle), which is a great advantage considered how exposed the vanes would be and how easy would be to damage them.

In summary, this is a very simple and effective way to enhance the looks of your Su-7.

Highly recommended.

I would like to thank Master Model from Poland and IPMS/USA for the review sample.
