Section 21: Ailerons (62 / 284 wings / 621 total)

This is a belated update on ailerons. November and December have been hectic months, and thus, the web updates suffered.

When building paired parts, such as the ailerons and flaps, you can build the left and right pairs in series, in parallel, or something in between. I think the series method is definitely not for me. Amazingly, the left part, which is started first, usually has better results than the right part.

One explanation is that when building the left, i read the plans word for word. When building the right part, i will tend to scan the plans, which may have unintended consequences.

One exception was when drilling the aileron counterweight. The plans call to "mark" the counterweight, instead of match-drilling. I interpreted this to mean, start the hole in the counterweight and then complete the hole after disassembling the part. The stainless steel (SS) counterweight is much harder to drill. I should have taken a more time to take an "accurate" mark, as the initial mark was probably not as centered as it should have been.

Another tip is shown in the above photo. The left part is shown above the right part below. The right part has scuff marks, whereas the left does not. In fact, these same scuff marks appear on all my previous trailing edges.

What happens is i back rivet the trailing edge, as one of my last steps. Because of the angle, the part will slide across the back rivet plate, causing these scuff marks.

The left part is missing these scuff marks because my back rivet plate was covered in saran wrap. I had wrapped the plate in saran wrap while building the fuel tanks to make it easier to clean up any oozed out proseal. The saran wrap seems to do an excellent job at preventing scuff marks from the back rivet plate. From now on, i am keeping the saran wrap on. I will test this on the flaps to see the final results.

Also, I noted that the right aileron TE did not come out as razor straight as the left TE. I did these TE's without using proseal. However, on the flaps, which are much longer, i will probably use proseal and compare the results.
