Default Sailplane wing visibility

On another thread I asked about making your glider more visible against the sky, saying I thought I'd read that black tape is used to put stripes on the underside of the wing, and got one response saying, "No, it's paint". I'm still not sure about this...

What do you use? Thanks.

Depends on your materials, aerodynamics, and how much weight you want to add.

Say on a Radian XL 2.6m sailplane...for example. In photos/videos of sailplanes, the material looks like some kind of vinyl tape...

Default Light on top, dark on bottom

If it's an ARF, already covered, put some dark stripes on the bottom and nothing on top. If it's already covered/painted dark on bottom and light color on top, you're all set.

If it is plastic covering, then use similar material (monokote, ultrakote, etc). If it is painted, use paint or vinyl sheets.

It's really up to you and whatever you have on hand.

Neon Green on the bottom in 2" stripes will make it easy to see even in a hazy white sky. That's what I have on my Bird of Time outer wing panels.

Tape off the stripes you want with masking or painter's tape. Buy your preferred color of cheap acrylic paint from Walmart or Michaels and brush on in a couple of thin coats. Pull the tape and you're done! Touch-up as necessary! I run wide black stripes that stand out under all conditions.

I like to make the outboard starboard side panel completely black. This helps to maintain orientation when flying at high altitudes. I use black film (removing the original film first). Some additional contrasting color on the bottom of each wing, as others have suggested, is a good idea.

I would like to try the green strips as mentioned, we get hazy whites sky's here in N Cali. I currently use black strips on underside of right wing.

I just make the bottom of my sailplane wings a dark solid color, no stripes.

I just put new wings on my Radian. I covered the bottom of the wings with dark purple packing tape so they are more visible against the sky. Works great!

Spray paint for Radian with any kind of paper to keep it in line SPRAY LIGHTLY repeat if needed. Lighter than tape too.
