YOU GOT THAT right!!!!!!!!
The BME site reads "1429" for the Yak wing area; who knows??
Then, of course, there's always the age-old question of "do you include the area of the FUSE between the wings?" (I have *never* been able to get a real definitive answer on THAT one!)
So .... like you said .... we're left to try to figure it out by trial and error.... of course then that limits the usefulness of subjective comparison.
Still fun to see which is "better", since I'll do both side by side, more or less, with the identical powerplants.
