Towerhobbies says I need 3 6' rolls of covering for a Tiger 60. Have never covered I have questions. Say If i want one color on top, one on bottom, and a third on top and bottom (Large pieces so I wont have to cover the entire wing with one color then add other on top), then can I just get on roll of each. How many rolls does it usually take (Tiger 60 or equivalent size plane)? Can I get away with 3 different color rolls, or what. Thanks
