DC, what a nice build of a rather complex airplane. I completly get where you're coming from with reducing this model to 1/6th, I'm just now in the finishing stages of my Proctor E-III. At 1/4 scale, it's a bit tricky!! I can't imagine doing one smaller while retaining the internal detail. Well done.

You can also check local thrift stores for aluminum cookware. If the diameter is off a little bit, the partial cowl configuration on the E-III will allow some fudging.

Again, good work.

John
