Building the Extra300XS

Under the fiberglass cowling the Saito 1.80 was side mounted.  The carb was  rotated 180 degrees to allow easier access to the needle-valve.

Side mounting the engine permitted the use of a Slimline Pitts muffler with smoke support.  Fuel lines connect to a DuBro QwikFill valve.

Looking aft down the inside of the fuselage.  The rudder servo is in front with wires to the rudder horns running to the back.

Standard 1/4 scale civilian figure.  Painted to match plane colors.

Close up of the engine without the muffler.  A 16" (16x8) prop was used and capped with a 3" TruTurn aluminum spinner.

Inside the main servo compartment.  The receiver was wrapped in foam and tied in place with black nylon straps.  A reversing Y adapter was used to allow symmetric mounting of the elevator servos.  The Y module is padded and mounted for here for easy adjustment.

Completed plane.  Wing decals added later.
