Oh, yeah. I should have known by your TH-cam handle. Cool little airplane. 😆 I've heard the Sonex wings can be removed or installed in about 20 minutes. But, obviously, I have a long way to go before I can do it myself, so I can't say for sure.
There is absolutely no need to throw away self locking nuts after only one use, despite what anybody tells you. And videos like this do not need elevator music to make them interesting, it's just annoying and distracting.
Thanks for the constructive criticism. I personally prefer videos with some music, but everyone's entitled to an opinion. Thanks for sharing yours. Regarding the reuse of nyloc nuts, take a look at AC 43.13-1b. It states: "f. Fiber or nylon locknuts are constructed with an unthreaded fiber or nylon locking insert held securely in place. The fiber or nylon insert provides the locking action because it has a smaller diameter than the nut. Fiber or nylon self-locking nuts are not installed in areas where temperatures exceed 250 °F. After the nut has been tightened, make sure the bolt or stud has at least one thread showing past the nut. DO NOT reuse a fiber or nylon locknut, if the nut cannot meet the minimum prevailing torque values. (See table 7-2.)" However, "Table 7-2" only specifies minimum torque values down to 7/16" bolts, so the AN-3/AN-4 (e.g. 3/16" / 1/4", respectively) nuts I've replaced on my kit aren't even listed in that table. My interpretation is that you can't reuse a nut that should only be reused according to the torque spec in that table if it's not listed in the table. More importantly, though, you can buy a pack of 25 of them from Aircraft Spruce for $2.50. There are several of those nuts that are within the riveted skins of the wing. I'm not taking any chances that any of them backs out just because I want to save a dime and then have to drill and re-skin my wing - or worse, have a wing crumple midair - because I didn't want to spend literally a few cents to replace a nut. Obviously, you're welcome to your opinion/interpretation but I'd strongly caution against what you're saying. There's no reason NOT to replace those nuts.
I'm not building a Sonex, I'm building something else but this was very well done and interesting.
Thanks for the compliment. Much appreciated. What are you building? I watched your videos and the routing/cnc stuff piqued my interest.
@@dan_der_flieger I am slowly building a CriCri, been around 14 years so far. How easy is it to remove the Sonex wings?

@@dan_der_flieger must be a little more involved than it is to remove the CriCri wings. Looking forward to seeing your build progress.
