Through a full summer of flying, I only had a handful of flights of over a minute (not including sloping of course), and never specked it out from a hand launch. I don't have a good scale, but my lace wing (in the photo album) was built with light wood (borrowed a .1 gram scale to weigh my balsa stock), little glue, relatively light covering, GWS pico receiver and HS-50 servos. I do fly with a 110 mah 4 cell nicad pack however. I've been thinking of building another Bug and will take your advice regarding the 1/8" tail boom and maybe extend the wing.
