Hey Gunns, thanks for the reply. I'm looking over your thread now and I've run into most of the same problems, with the PE parts for the interior rigging I ended up having to just tear that rear most panel out and toss it because no matter how clean I got the existing rigging sanded down it just would not allow the two fuselage halves to go together, even after taking it out I had issues so I just sliced about a mm off of each side of the seat and then it went together fine.
I've decided not to rig the interior, I had some plastic sprue stretched out and ready but ultimately I care more about the final paintjob and rigging on the exterior than how the interior turns out and I'm still pretty new to rigging.
I plan to use the "A" option decals with the 4 bladed prop and head rest and I want to get the color more towards the brown side like your phoenix se5a, here's a blurry picture of where I'm at now.

I'm running into a lot of walls because I don't have all the paint I need to actually start doing the necessary pre-assembly paint application like where the vicker is mounted among other things.
For the gap where the cockpit cover goes on I went ahead and just used the plastic glue, waiting for it to dry so I can sand it ever so carefully flush but in case I mess up all the stitching detail I went ahead and scrapped the extra fuselage parts I had and cut off all that stitching detail so if I mess it up too bad I can just sand it down and replace it that way.
After this the only things I can really do before Wednesday is the engine, vickers and lewis and the struts then I have to wait until my paint arrives.
Also I found some white surface primer used on canvas and it actually serves as great filler putty, if this glue doesn't work really well I'll apply some of that, it's thick like paste so it fills gaps easy and dries hard.
