Looking good. This is a nice kit in terms of the design once you get past the flaky nature of some of the parts and some of the fits. It can be made to fly quite nicely.
Don't use the rubber in the kit, it won't work. 3/16" rubber is about right I found. I went 1.25 times prop to hook and still got a 25-30s motor run. For simple motors like this one "braiding" is simply twisting the rubber along its length before I tie the knot.
I would recommend that you add corner gussets to your wings, both for strength and for avoiding "dipping in" of the tissue and wrinkles.....
Because you have removed a fair amount of material from the two pieces that form the inside rear of the tail (stab.) ie the part that clears the movement of the rudder on the real thing ( I hope you understand which bit I mean) I would consider adding some gussets there too as it looks a little weak.
Don't forget to add some washout to the wings when you shrink the tissue, this will help keep things stable esp. on the turn.
I think most of this is in my build thread.
For what it's worth I'd just use the coloured tissue on this one, I painted mine and it was a bit OTT for such a simple model really, but my daughter wanted it that way.
I look foward to reading the rest of your build......
