When setting out to create a scale documentation binder, I have to have color plates and 3 views that match the model I am creating. Since I am doing a B model, I specifically need certain things. I currently have several books, but nothing I can use to create my booklet. So, If I were never able to find documentation with a straight chord aileron, I would have to build a tapered aileron to match my docs, even though that is not truly scale! I would rather not have to do this.
