louie525, I don't believe that you and lablover are on the same page with me. You may well be a paint professional in painting and restoring classic cars,etc. but what I am talking about and have developed over the last 24 years is related to pattern planes only. To start with I only use primer on the seams (and sand off most of that) and NEVER use clearcoat. The key to a light wing starts with contest grade balsa (preferably 4 lb wood) and using the least amont (measured) of laminating epoxy or polyurethane glue you can get away with. There may be some builders that can control the weight of a painted wing but in recent years I've had better results with Monokote. To give you an example, I just completed a Mystic plane with an all up weight (minus batteries) of 7 lbs 7ounces. Each Monokoted wing with servo and linkage weighs in at 12.3 ounces. Like I said before, if it has an all up weight of more than 10lbs 4 ounces, I can't use it! It might be to your advantage to check with some of the pattern plane builders in your area. Regards, Everette
