I am working on FDE for a Supermarine Seagull / Walrus, and
am seeing very large drag values in both Airwrench and the Flight Dynamics Workbook.
Would you kindly comment / teach about the Zero Lift Drag numbers
as indicated by the Pics Below, and how they relate to the specified Horsepower and other pertinent settings such as prop efficiencies ?
Thank you for your consideration,
