Thanks guys for your nice comments.
Scott - when I said the word ailerons I used the term loosely, they will be part of the wing as per the original aircraft and will be the warping type, I found it easier to do this part of the build in two parts. Once I make the 'ailerons' they will be attached to the wings and will appear to be as one, I hope. As you know, the warping part of the wings were made of bamboo, they were bound to the wing ribs so there was a difference in thickness between the ribs and the bamboo giving a step, I hope to replicate this.
