If that is true, can anyone tell me how much curve to put in the tail surfaces?
Thanks. I thought I was going to whip up a quick test cone to see what the results were. Ah, grasshopper, you have much to learn.  |
I do not think that we should attempt to copy the shape of a wing. Wings are designed to use airflow to create lift. The action of creating lift with a wing induces drag. The best thing to copy is the fuseloge of an airplane. Euromodder might be correct. Flat panels might give you the same basic result. Of course you would need to round the corners where the top and sides meet.
