RC plane wing spars with integrated aileron by northshore Oct 1, 2012


Updated files loaded.. no need for external support on the aileron, makes for a 50% faster print. Further revision with increased pin size for strength.

As per the title.. 3 parts, a left and right wing spar, with an interally fitted aileron / flap, with hinge pins.

Made for use with 1.2mm balsa sheet on the leading and trailing edges, a balsa beam in adjacent the trailing edge as well as a 6.1mm square carbon rod for the centre support.

The opening behind the COG has been sized to fit a 5g servo.

There is also a pad on the aileron for mounting the control horn in either a left or right hand configuration.

Heat shrink film covering is recommended, or celophane with spray adhesive, but this does tend to break down with uv exposure.

20% infill, 2 - 3 shells as desired, and .2mm layers.

The internal spar's are more sensitive to feedrate.. have slowed it as low as 40 to get a nice finish.

The aileron can be run at a feedrate of 55-60 and a travel rate of up to 80 of you dont mind having to clean it up a bit afterwards.
