Rudder Preparation
23. Locate the rudder, the rudder control horns and the 2 slotted base plates.
Use a sharp #11 blade to remove the covering from the 2 pre-cut slots in the
rudder. Trial fit the 2 servo horns through the slots in the rudder and into
their proper position. Remove the control horns and cut away the covering
from the area where the base plates will go as done previously with the aileron
and elevator. Mix up some 30 minute epoxy and use a small blade to fill the 2
slots with epoxy. Use plenty of epoxy and be sure to completely fill the two
slots. Use an epoxy brush to completely cover the areas on the rudder horns
and base plate that will glue into the rudder. Slide the rudder horns back into
their proper position and immediately wipe the excess epoxy from the horns.
Place 2 3mm screws through the outer holes in the horns to maintain
alignment. Carefully check and re-check alignment to insure proper
positioning. Use some denatured alcohol and a paper towel to remove any
excess epoxy. Re-check the alignment one more time and set the assembly
aside to dry.
