The root cord (center cord) is 22 inches. The tip cord is 4 inches.
The sweep distance back is 15 inches, to give a nice 45 degree delta.
Used this web page for balancing model:
http://www.palosrc.com/instructors/cg.htm
I entered these parameters as follows:
Enter Root Chord (A): 22
Enter Tip Chord (B): 4
Enter Sweep Distance (S): 15
Enter Half Span (Y): 15
Enter %MAC Balance Point: 11
This gave me the following output
Sweep Distance @ MAC (C) = 5.77
Mean Aerodynamic Chord (MAC) = 15.08
MAC Distance from Root (d) = 5.77
Balance Point @ Root Chord (CG) = 7.43
The only number I have used here is the CG of 7.43 inches for balancing the model.
Do you think my maximum thickness point should be at 7.43 inches as well?
Thanks
