I would like some basic measurements to start with, based on the facet 1200 as I like that concept.
As I understand it the Facet is a short kit anyway, the builder must supply some of the wood for the kit (I'm not sure exactly how much).
It looks like a great flying jet trainer and it is very reasonably priced.
Unless you are just dead set on designing your own turbine trainer it sounds to me like the facet kit might be just what you need, so why re-invent the wheel?
