This is a Czech Model kit in
1/48 scale. It's a limited run multimedia
kit with both low pressure injection molded parts and cast resin parts.
As such it is a more laborious build with lots of test fitting and
usually lots of sanding and filling. This aircraft was one of only two
cases where a piston engined aircraft was successfully converted to jet
power. Al of my trials and tribulations can be seen in the build log.
It's a fairly simple kit and in spite of the issues I had fun building
it.
Next are some comparison photos taken with the YaK-3 which was the
aircraft that was the basis for the YaK-15.
