Some time ago I got the Vostok launcher kits from Apex. They
are good enough in basic dimensions, but the Vostok stage is very
simple, without correctional motors. Because there were 2 versions of
this stage, I decided to do both. This is only a simple description how
to do this, if you want to do more detailed models, see drawings and
photos.
First I made the Luna launcher. I
used the 1/144 Vostok kit from
Airfix to add some details to the Vostok stage as shown. I removed
the upper part of the Vostok stage and added the Sputnik cone to it
(see drawing).
After that I made the Vostok launcher. The worst problem was what to do with the aerodynamic shroud of the Vostok spacecraft. I decided to use the Voskhod conversion kit from Rho models (see drawing below). The result is much better.
