Speed brake installation
The operational speed brake is an option
B
for this airplane, but it is highly
recommended to be installed and used.
A
The speed brake is very efficient and has
no pitch up or down effects when
deployed. A skilled use of the speed brake
will always be the best option to control
speed and sink rate during landing
C
approaches, for formation flying and
anyway will be very impressive for slow fly-
bys.
It is the easiest solution to mount the
pneumatic cylinder of the speed brake
door right on to the tanks.
The distance A is 36cm at the maximum
opening angle.
The distance B is 26cm and the position of
the connection point (control horn) at the
speed brake door. The distance C is then
the resulting mounting point of the air
cylinder to the tanks.
Prepare a pair of aluminium brackets like
shown on the photos.
The hole is located just above the top wall
of the tank.
The outer contour of the brackets with the
rounded edges and recesses is necessary
to fit the pneumatic cylinder and allow free
movement.
