I just measured the weight of all of the parts contained in the box :
All of the main parts including the fus.with the canopy, wing, and the tail feathers came to 61oz. The balance of parts including the control rods came to 34.6oz. This comes to a tidy 6lbs if you round off the 4oz.
I glassed the center section of the wing because I thought the center attachment block looked too light to suit my taste.
Be sure to releave the center of the two small bulkheads in the belly pan to clear the slight diheral in the bottom of the wing (and the added glass).
I had some small problems with the paper tubes in the belly pan but I am not complaining.
May the weeds in our garden turn out to be wild flowers.
