The fly tying thread is a good idea. The problem is to lay it without deforming the structure and with constant tension. It is necessary to imagine a solid frame but without making it difficult to access the model. Why not but not obvious.
The use of EZ thread is perfect for some uses but I don't think it is the solution for a 1/33 biplane because it is elastic and doesn't stiffen the mounting in any way.
Thank you for your help.
