Quest Aurora Build, Part 4, Balsa Grain Directions?

The die-cut balsa pieces were already broken (not cut off) the sheet.
The glider rudder was half as long as it should have been, the front end was broken off and missing!

Check out the grain direction on the rudder. That's not the strongest direction for the balsa grain to run! The grain should be parallel to the leading edge of most fins.

I didn't know how long the front end of the rudder should be.
The rear of the rudder is even with the back end of the wing.
The curved line of the leading edge was extended to approximate the end length.
A new rudder was cut from 3/32" balsa with the balsa grain running down the leading edge.


Only one of the small rudder pieces had the grain direction correct.

The picture shows how the pieces were positioned on the balsa sheet.
After the correct small rudder edges were cleaned up, a new one was traced an cut out.
