I got an answer from Max at BME:
Hi Daniel
The wing area of Edge 540 is a little more than 1300 sq.in.
The total weight with a BME 50cc is 15 1/2 lb.
Thanks,

15.5 lbs mean 27.5 oz/sqft wing loading which is Very good for giant plane that size. Anyway, the wing loading seems very near the WH Edge at 17lbs 28.1 oz/sqft.
I feel, both planes would be very similar in flying performance. Life is difficult for me. I must decide between WH Edge, BME Edge or AW 29% Edge kit now[
