Hey JonTom, by any chance, was there ever a pic with a clear view of what kit parts they used for the Betty cockpit interior? I looked at your pictures in that link over many years but never could make out what the interior look like.
Kun28, I think screen caps will be your best source for the cockpit.
I finally have some progress to show. I received the first batch of printed parts. All parts, accept one, are perfect. One part has a warp on an interior wall, but is easily fixed. A slight learning curve for parts design. I fitted the engine to the wing and it fits as I intended. The small wings on the bottom also fit perfectly.
I have replaced the damaged and uneven styrene with new straight sheets for mounting the boxes to. The client will be doing all of the finish painting. With that in mind, I will be making as many part as possible to be removable to allow for better finish painting. The boxes have been cleaned enough to allow them to fit on the sides and next to each other.
Thanks for looking!
