I forgot to say earlier in this thread that although the Bill of Materials (BoM) lists the various labelled parts (NC cut & stripwood), I thoroughly recommend going though the BoM against the parts and drawings before you start any of the build.
The reasons for this are to (a) check off your laser cut kit parts, (b) identify where each item fits on the plans & (c) identify the stripwood required to be ordered, (d) split the NC parts into various build groups (e.g. fuselage, wings, tailplane, rudder).
I also noted the purpose of each part on my BoM to help later on.
In doing this, I identified a few items that had been accidentally missed off the NC cutting files and a couple of wrong quantities (drawings since amended), but also identified a couple of items which didn't appear to be mentioned anywhere on the various drawings.
Items which fell into this latter category are GUS1, V13 & V14.
Jilles has provided lots of additional information on the various cross sections provided, but the above parts don't appear to get a mention on any of them. So...
GUS1 is a small slotted gusset which is used when glueing the elevator servo tray ST2 to the top of the forward fuselage deck DKD. It will be apparent from the tab/slot which way around it goes on the front of ST2. A photo below shows GUS1 in place.
The V13/V14 items fit at the very lower rear of the rear fuselage (tail skid area).
A problem I find with CAD drawings is that there are so many lines on them that it is sometimes difficult to decide where some parts end, unless you have an infinite number of notes/sections to show what is going on.
This was the case when I was assembling the fin post, as although there is a drawing note on the skid area saying that CS3 (carbon strip) & V5 go to the bottom of the skid, it didn't mention the V6 strips each side of the CS3/V5/CS3 sandwich and also didn't mention the NC cut V13/or V14 pieces.
Once you realise that V13/V14 actually fit into this area, all becomes clear .... albeit somewhat belatedly for me
The V6 parts stop at the lower level of the bottom rail (V2,V4,CS2). The V13 piece fits on the bottom of the V2,V4,CS2 rail, forward of the V5/CS3 sandwich, with the V14 pieces acting as doublers & going each side of the lowest part of the V5/CS3 strip.
I mistakenly took my V6 strips to the bottom of the skid and have had to cut the rear off each V14 piece to get them to fit in the remaining space.
Note that this area is further doubled by the two outer V15 parts, so I don't think it will be a problem.
The photos below show V13 & the 2off V14 parts (one of which has been shortened), the underside of the skid area, both before & after fitting the V13/14 parts.
