Gerry, spoken like a true gentleman.

i realize you're restricted in what details you can share, but do you have a rough timeline yet? E.g., approximate dates when a drawing might be released, when the configuration will be locked down, etc.

Also, most of the discussion has centered around a PT-6. IIRC, your original post mentioned alternative engines. Can you give us any insights as to what alternatives the designer might be considering?
