Thank you Ian for the link to the magazine!
The balsa wood I've ordered arrived today. I will start to cut the parts for the wing tonight. Smiley

Unless otherwise specified, assume that all material is 1/16" thick.

Thank you Neal and Mike, your answers are very helpful for me and the things become clearer now. Also the pictures are good for understanding (the plane looks realy good btw.).
Now I'm searching for balsa but I don't know which material thickness I have to order for a model with 13" wingspan. In the plan is described that I need 1/32" for the fillets and the top combing for example. But which thickness do I need for other parts like wings and ribs?
Thank you in advance!
Rolf

Welcome Rolf!  Neal's got your questions covered pretty well. 

Regarding the wing fillets, if you choose to do them you'll just cut a piece of 1/32" balsa matching the triangular portion of your red-circled shape that lies behind the trailing edge of the wing.  That gets glued to the aft edge of the wing and fuselage and makes the bottom surface of the fillet.

On the top side you'll trim and fit a piece of ordinary printer paper to go between the wing, fuselage and bottom piece of the fillet.  The upper paper fillet can be broken up into a couple of segments to make it easier to smooth the curves (that's how the sheet metal was done on the real aircraft). 

This is usually an iterative process of fitting and trimming that'll take a couple of tries to get to where you're happy with it.  Here's a couple pictures of the fillet on a larger Spitfire model and the fillet on the actual aircraft.

Keep posting - looking forward to seeing your model come together.

Cheers,

Mike

Welcome, rollov!  Red outline is of the wing fillet planview...no pattern for such seems to have been provided on plan.  I wouldn't trouble myself with that feature just yet.  The cross refers to the aircraft's longitudinal center of gravity...a proposed balance point necessary for successful flight trimming.  Again...not to be concerned with at this time during your build.  When the model is finished and you're trimming...you can add weight as necessary to achieve balance at that point.

Glad you've joined us!

Neal

Hi S&T community!
I'm a beginner and want to build a spitfire from a plan made by Walt Mooney. But before I can start I have to understand all details of the plan. I've marked two parts with red colour - would be nice if you could explain.
1.) what is this outline? is it a part made from balsa wood?
2.) what means the cross? It seems to be related to the ribs C and G

I've more questions but that's it for the beginning. Smiley
Thanks in advance!
Rolf from Leipzig
