The parts for the left elevator are assembled and then match drilled with the left skin. Here is the elevator horn being match drilled to the elevator spar.
Then the parts are scuffed with Scotch brite before dimpling and prior to priming.
Carolina makes an appearance, but hopes to avoid the paparazzi. Here she is dimpling the counter balance skin.
After priming the skeleton is reassembled.
Roxy standing by. Or laying by -- to be precise. Her main concern seems to be keeping the squirrels out of the yard and, by logical inference and deductive reasoning of her superior canine brain, to be certain that the furry rodents are not interfering with the construction of this airplane. Good dog!
The next order of business is to fabricate the trim tab. For the non-pilot, the trim tab is a control surface that is adjusted from the cockpit that allows the pressure felt through the stick to be zeroed out. This plane will have electric trim, which means that a switch in the cockpit will be used to control a servo motor in the left elevator, moving the tab. A nonelectric trim tab uses a control cable instead of the servo.
The trim tab is the most feared component of the entire tail assembly. One builder's blog I read recently suggested that one should buy two trim tab skins before starting because it is a near certainty that the first one ends up in the scrap bin. We'll see.
While I procrastinate on starting the dreaded trim tab, I'll assemble the trim servo access plate.
