I just build with super thin CA through a tiny tip and sand everything well when done. Parklite covering would be best but on mine I used regular ultracote. Transparent covering is lighter than regular covering but still a little heavier than parklite. I used fluorescent tranny red on my slick and flour tranny yellow on my glitter jr. I loved both colors.Nice flying Jake! Looks nice and floaty. What did you cover it with to keep it light?
