Retract - Brake valve instructions
The
C21 retracts are air up spring down units. Any pressure loss
during flight will cause the struts tocome down automatically.
The retraction angle is 90°.
Unlike other manufacturers, our one part retract bodies
with cylinder are machined from solid block (F50 specifications),
and all aluminium parts are anodized to minimize wear.
This retract is extremely strong
and very light. Set includes all necessary fittings as well
as a retract / brake valve to eliminate the need for an
extra servo. The C21 retract is compatible to the 602 Spring
Air retract.

C50 retract set
The C50 retract set is designed for use
in larger models, up to 20 kilograms (45Lbs).
It is a double action system ( air up- air down). Like
all of our retracts, the main body is machined from a
solid block. We use only the best available aircraft grade
aluminium ( F 50 specification ) and all aluminium parts
are anodized to minimise wear. The piston diameter is
20 mm and this allows it to lift up heavy struts. The
connection between retract and strut is drilled for 8mm
hardened steel rods. Retraction angles of 75°, 90° ( standard
) and 105° are possible. The retract bodies are available
as standard in "flat mounted" or "front
mounted" units. The 105° version is only available
as a front mounted unit.The actuating valve is
also able to operate wheel brakes without the need of
a separate servo ! ( 3rd output
)

I have been asked about a self centering solution
for the C36, C36/2 and C50 retracts. Although not needed,
you can modify your retract to self centre as per picture
below.
