Today I spent a long time preparing the outboard tailplanes for shaping the tips. First I put on masking tape at 5.5cm around the tips, then plotted the shape. I first made a template from card, as this would help me get all the tip shapes the same to each other. I cut away the tip to the shape, now it is already for sanding to a nice rounded tip. I also put in the venting holes in the lightening holes to stop the tailplanes blowing up like a balloon at different altitude pressures.Later, I sanded and profiled the Tip's. Looks Really Good!!!
