Bottom Rudder And Servo Installation - Carf-Models MiG-15 Construction Manual

5. bottom rudder and servo installation

Work Steps:
- Cut the hatch and shape the parts to fit the rudder
- install the rudder with Robart hinges and torsion linkage
- set up the servo linkage and mount the servo and hatch
You need:
- cutter, dremel milling tool, round file, drill bit 5mm
- CA Glue, Epoxy glue with some milled fibre
- fuselage, one-piece-stab, bottom rudder
- milled rudder servo mount, 3 robart hinges, torsion linkage,
2 pushrods 2mm, 2 clevises M2, 2 threaded ends M2,
rudder servo, extension servo lead, 2 sheet metal screws
Your MiG-15 has only the
bottom rudder working. the top
rudder is fixed. This simplifies
the system very much, and at
the same time reduces the
chances of flutter. The one
bottom rudder is very efficient,
so that you would never feel
the need for the top rudder
working as well.
Start with cutting the servo
hatch. both sides of the rudder
fin shows a hatch in the center.
Whichever one you pick, is up
to you. Cut one hatch out with
an X-Acto knife.
At that time you can install
already the frame, to mount
the hatch lateron. 2 scrap
pieces of thin plywood do the
job, just glued in on the top
and bottom radius of the hand
hole. Use 2 sheet metal
screws, one each at the top
and bottom radius to fix the
hatch.
