I know exactly how you feel Old Mill. My first covering job was on the 76" wingspan GP Cub. The ribs on the built up "barndoor ailerons" on mine were flat and they turned out fine. The hardest part for me to learn was covering the wingtips and the fuselage stringers between the cockpit and the tail area. Just do what Mike and Chris suggest. Read the covering article and don't be in a hurry. Also buy at least one more roll of Cub Yellow Monocote (I'm just assuming that's what you'll use) than the instructions recommend to allow for some mistakes, and invest in a good covering and trim iron, a good heat gun, and one of those heat resistant gloves for gripping the covering when doing the wingtips. Who knows? After you've built and covered a few more planes, you may actually begin to enjoy the covering process! Good Luck...Len
