REDWING RC 50CC EXTRA
NOTE:
This is the time to test fit the cowl and
ensure no adjustment is needed. Proper
spacing to the spinner back plate is 6 3/4"
(172mm) from the firewall.
--The PTE 72cc Twin requires a 3/8” (10mm)
spacer added to the included standoffs.
•Next determine where you will need to mount
the throttle servo to properly align with the
carburetor. You may find you need to rotate
the carb or modify the throttle arm for proper
geometry.
NOTE:
A gusseted mount is included and can be
mounted anywhere in the forward fuselage
using 15 min epoxy. Ensure you do not interfere
with the position of the other components that
will be installed later such as the fuel tank and
ignition.
--For the PTE 72cc Twin the low carb position
requires a lower mounting of the throttle servo,
so it was
mounted
as shown
in the
floor of
the motor
box.
•Determine the mounting position and prepare
the servo while the epoxy is curing. Install the
grommets and
inserts and
secure the
extension to the
lead at this time
if needed.
From the Pro:
Use
heat shrink tube to
secure the servo
lead to the
extension.
•Drop the servo into place and drill for the
servo screws with a 1/16” drill bit. Then,
remove the servo and thread a servo screw in
and out of each hole. Then apply 2 drops of thin
CA to each and allow the CA to soak in and fully
cure.
•Before installing the servo, determine the
position of the ignition module and fuel line
routing thru the firewall so that you may
remove the engine and drill all holes needed.
