10.1.3 Aerodynamic Trim (Sparrow Strainer)

Over the years, whenever I was waiting for something to cure or dry, I would sometimes spend a minute or two on the sparrow strainer.  This is a small inverted airfoil that attaches to one of the elevators. Just like the vortilons, when it was time to finish them, I let Malcolm do it.

Before starting the finish work, he created a pair of flanges where it attaches to the elevator. Once the flanges were done, he began the sanding, filling, sanding filling process. The the gray primer, more filling and sanding and finally the white primer.

Here’s the end result.

It will be attached to the inboard end of the right elevator but like the vortilons, I’ll wait until I’m closer to flying before attaching it permanently.

Here it is dry fitted.
