So I ordered some 'pre-foamed' PLA to print the Dusty plane. It just seems the files are not well suited to the 'foaming' PLA. I am currently printing a part of a different plane (found on thingiverse) that seems to be going well with the LWPLA.
The picture with the two pieces, the worse looking one was at 100% flow, the better looking one was at I think 50% flow, it would probably be sufficient, but I am just scrapping the plan and going to use pre-foamed PLA for it instead. The pre-foamed is a little heavier that foaming, but supposedly prints very similar to regular PLA. I will save the foaming PLA for files that are optimized specifically for it.
