The July 2007 issue of Fly RC contains a free pull out plan for the Blue Flash, a glow powered .25-.40 size sport flyer.
The classic lines are augmented with traditional balsa construction, along with a modern airfoil and flaps for fun at the field. The following materials list and this downloadable cutting guide (PDF format) will help your plans building efforts. Please contact editors@flyrc.com with any questions.
I did not itemize the materials or components used as I built my original prototypes. The following is an attempt to list what is needed to build this model. Go over the plans, this list and the cutting guide to determine what else you might need. I recommend buying extra balsa to have on hand in case you need to make extra parts, and to ensure adequate material quality and sufficient supply while building.
