Speed Brake Doors - Carf-Models MiG-15 Construction Manual

8. Speed brake doors

If you do not want to operate
the speed brake doors in
flight, you can skip this
whole chapter 8.
But a plane that scale
should definitely have the
speed brake doors working,
and they are very efficient
too.
They work more neutral
than the flaps, and for that
reason they are highly
recommended!
This is again a working step
demanding a good amount of
skills and
PATIENCE.
First, cut out the 2 speed brake
doors at the rear end of the
fuselage. You can determine
the shape by checking the
panel lines. They are correct
and do not need any further
modification. After you cut out
the doors, sand the cut slightly,
and make sure that your cut is
not too wide. That's why we
recommend to use a cutter
blade only. Do not use any
electric milling tools at that
stage.
