Thank you again for the offer. Here's my own wish list: 1. Aerodynamic coefficients You probably won't be able to find these anywhere, unless your airforce once did wind-tunnel tests on a DC-3/Dakota, but these are what JSBSim needs to model a DC-3 correctly. There will be a lot of numbers or tables with headings like CLo, CLa, CDo, etc. (or maybe CX*). I saw a story that someone once requested this data from Douglas, and an old engineer at Douglas replied that the DC-3 was invented before aerodynamic coefficients were (I doubt it, but it makes a good story all the same). 2. Raw flight data It is also possible that someone has collected in-flight data from a Dakota, and we might be able to use that to calculate some of the coefficients: for example, there might be tables of the engine power required to maintain altitude at different angles of attack, or the climb or descent rate at different power settings and altitudes, etc. 3. The DC-3 Pilot Operating Handbook In an ideal world, a PDF of the whole POH would be very useful to everyone working on the DC-3, but in reality, copies of the power tables alone would make a big difference to our modelling efforts. 4. Wright Cyclone Engine Data Any engine performance or maintenance data for the Wright Cyclone (or whatever the later DC-3 engine was) would of course be very helpful. 5. Interior and exterior 3-views I have some low-res 3-views of the DC-3, but any more detailed drawings would be helpful, especially for the 3-D model. Detailed drawings of the cockpit and control panel would be great for the panel designers. 6. Pictures Lots of digital pictures of details, especially the cockpit interior, would be very nice. 7. Any unexpected surprises You'll probably find things we didn't even think of; please let us know. In addition to all of the dry archival work, you are more than welcome to load my DC-3 3-D model into Blender or another modeller and fix it up, especially if you have access to any real DC-3s/Dakotas for comparison -- let me know if you'd like the latest version.
