You cant increase your speed by 20%...but you CAN DECREASE your useful load by about 12% (if I have my numbers right). Fir is a little heavier than Spruce. I just finished a new battery box for my Fly Baby. Actually TWO battery boxes, after the first one (made of oak) got laughed out of my EAA chapter. (Hey, I do a bit of non-aviation carpentry. I *love* working with oak!) FWIW, the poplar one weighed 1.25 pounds. The nearly-identical oak one weighed a half-pound more... a 40% weight penalty. Ron Wanttaja |
