Rudder And Tailwheel Assembly And Mounting - Extreme Flight 78" EXTRA 300 ARF Instruction Manual

Rudder and tailwheel assembly and mounting

10. 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. Measure to
ensure they are centered and mark with a fine tipped felt pen to make it easy to reinstall
properly when epoxy is applied. 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. 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.
