I need help! I have two Cubs one is GP 40 and the other is the Goldberg. I have mounted 4 strokes in both and nowI need to cut out the engine openings for both cowls. Now how the heck am I supposed to get the engine outline ( top down) onto the cowl sides? I have put this off for a long time as I can't seem to find any info or techniques for doing this. Grrrr Cubs don't look right if they are flying with their engines hanging out in the breeze. This has been most frustrating for me as the Goldberg Cub is now on floats and I really need to get this plane as well as the other one ready for the upcoming season. Thanks. Jollyroger
