Default stainless steel flap tape...

It's all been done before

Stainless steel flap tape!

Paint wear had begun to become aluminum wear from the flap wing gap seal.

Although I have a strip of UHMW tape under the gap seal it has not kept scuffs from developing. This setup worked fine for the first 500 hours or so but has not prevented wear since then.

Here are a few shots of the wear along with finished fix using 3" tape from McMaster Carr.

It looks really slick, but watch your fingers while installing... That tape is like a razor.

Default Consequences

Looks great. I'd add just to improve appearance.

Are there any unintended consequences, thus far?

Hi Chaz,
I put SS tape on a year or two ago. It still looks great. Another RV in our hangar has had it on flaps much longer and looks brand new. One roll from McMaster Carr will do about 3-4 RVs.

One thing to be careful about when using the stainless tape is to be sure the formed, curved leading edge of the flap is symmetrical the entire length of the flap. Otherwise, the inflexible stainless tape may not lie down properly without slightly creasing. (I had to tweak mine a little...)

Great mod, Stephen. I'm definitely going that route on mine. Functional, and adds a little bling too!

Our RV-6 (Kit #0004) has had the stain;ess tape on it since (I think) the beginning - still looks great. We have it on the -3, and the next time I have to change the tape on the -8's flaps, it is going to be stainless.

As Stephen pointed out, putting the tape under the wing skin just captures the direct grains so that they can scratch the paint on the flaps themselves - the very thing you are trying to prevent.
