I looked the Yak over real good a while back--nice plane and built like a tank so I don't doubt your weight--there is a good deal of difference in weight between these 2 airframes--the fuselage on the Yak is stout---good to hear it flies well--- I not going to get hung up trying to make the Edge as lite as a feather--if it doesn't fly to my liking I can always swap some things out to drop some weight
