Following on from part 1 of this build documenting the support of the wing supports, rudder and horizontal stabiliser (which can be found here: https://motorsportformentalhealth.com/2017/01/30/balsa-wood-super-cub-build-part-1/ ) We find ourselves building the main set of wings.
The wings on balsa aircraft are very similar in structure to those found on a real aircraft.Two long strips of balsa are joined together by ‘ribs’ which form the actual shape of the wing. The ends on this kit were laser cut and simply slot into place.
The wings are a little more involved than the part done in the first part as some modification is required. Take a look at the ribs in the picture below.
As you can see the back edges of the rib are very sharp which isn’t very aerodynamic. They will need to be shaved into a proper shape and the ends of the strips the make up the leading and tail edges of the wings will need to be cut to follow the lines of the preformed ends. Finished they look like this:
Here is the finished pair against the plan.
I know building from balsa is a time consuming process and that turns some aero modellers away from it, however balsa aircraft are incredibly relaxing things to build and it’s very rewarding to look back on what you have built. These wings aren’t exactly complex in comparison to some of the other aircraft people out there are building but I can still sit here and look at them as an accomplishment, considering I’ve never really had the opportunity to work with wood before.
That’s all for now I’m afraid! I’m just off to make a start on the fuselage. Be sure to comment pics of your balsa builds and as always be sure to follow me on Twittube and Faceagram!
