has anyone put cold light string on a heli before? how do you make designs on the canopy with it and what supplies do i need? ive already got a length of it coiled around my tailboom and it looks too cool. now i want to outline my canopy with some and i cant figure if i should use CA or maybe something less permanent. also, i've heard that you can cut cold light string to length, is this so and how do i do that?
