There is a video playlist for the A-10 as well as the F6F. It is simply that the repeated items that appear in every previous build video (eg, how to install servos, how to do a bevel cut, etc.) are broken out into a series of mini clips in the build video playlist to avoid repeated instructions. In the model release, both Josh and John mentioned that they would be using playlists for model build instructions - with a unique features model video if needed - when there is a video icon on a part, it will be detailed in the unique features video in the model's build playlist.
A hint is always open the videos in YouTube so you can see the playlists better.
When you click the link in the Flite Test Store for the A-10 build video it goes to the Intro and if you look the intro video is just part of a long playlist labelled "A-10 MASTER SERIES" playlist. The A-10 unique features video (part of the build playlist) is over 1 hour long at the end of the playlist, so it is all there - and also linked from the store.:
The F6F build playlist is also a linked from the Flite Test Store. Part of the playlist is a build video for unique items for the F6F, almost 1.5 hours long.
