I'm wondering how to best scratch build an rc aircraft and what rough proportions the aircraft should be in.
I'm aware of the fineness ratio that determines the width to length ratio of a cross section of a wing should be around 1:3 or 1:4, but I can't seem to find similar rules for:
The distance between the wing and tailplane
The length of the wings
Am I just better off just making a scale model of an established aircraft instead of using these rules?
