RE: Brent Good Custom Airframes 106" Yak 54
I just finished cutting the lightning holes in the first wing. I will be ordering the balsa next week. So hopefully I will be able to start sheeting soon.
I just weighted the lightened wing and the one that has not yet been done. I cut our 2.5 oz. of foam. I am hoping to save a total of 4 oz. per wing with the reduction in glue needed for the sheeting. The total weight for the lightned wing core is 10.2 oz.
