Default RE: My First Build BUSA E III
ORIGINAL: Tuskegee1973
B: I probably should have used 4 spruce strips inplace of the 1/4"x1/4"x30" balsa strips since I removed the original fuse sides and since spruce is stronger. Overall reason...I want to prevent the rear end from breaking off in the event of a hard landing. I will be adding diagonal cross braces in the top sections of the rear fuse (make sense?).[/size]
Spruce is too heavy and unnecessary for this application. The important thing is to keep the tail AS LIGHT AS POSSIBLE. As long as the longerons are HARD balsa, it should be fine. With (light) cross-bracing it will be virtually unbreakable and will probably even survive a crash intact.

As they say, build to fly. Don't build to crash.
