RE: ziggs originals zero build questions
It has been a long time since I built any Zigg 109s but I don't recall using any type of covering or fiber glass except around the nose. I painted them with thin coat latex house paint to keep the weight down. My 109s finished up at 23.5 oz. ready to fly with light weight radio gear and a 250 ma. battery and a Mecoa .15 motor.
