I think the same stuff could also be used to close out the big openings at the leading edge of the elevator. I may do that next.

I was also going to use it to close out the flapperon slot in the turtle deck.
I also thought about using it on the flaperon slots, but decided against it because the transparency of the turtle deck would show the Hysol glue mess thru to the outside. The simple 1/4" foam rubber closeouts stuck on with contact cement look much better and are simple to install.
The foam rubber also works OK on the stabilizer trim slots, but you have to make sure you use a fairly soft foam rubber because there is a lot of motion back there, and you don't want heavy pressure rubbing and wearing on the stabilizer tube as it moves up and down. That's why I thought the brush idea would be better, and it also looks kind of cool.

I also didn't like that. I would use E6000 adhesive. Its clear, flexible and requires very little qty to work well. I have used it to glue glass bottles together and it is very strong.
The brush seal idea is a good solution Jim and I'm planning on doing something similar. You may need to keep an eye on any dust or grit build up just as a precaution.

Another area I have always wanted to address is the space between the horizontal stabilizer and the base of the vertical stabilizer. This is a notoriously high drag area on all airplanes especially on the Kitfox because of the open gap. I have thought a soft foam of some sort would work here because it needs to move freely with the trim. Maybe shaped to the rib and contact cemented to the rib to allow the foam to slide on the empennage panel freely as the stab is trimmed. Once I find the right material ,I'll give it a go and take pictures. Bruce N199CL
Go for it Bruce. I think we're on a roll here.

Thin overlapping pieces of leather work well for the flaperon slot on the turtle deck. The forward piece overlaps the aft piece and the flaperon tube rests in a cutout area slightly larger than the tube diameter. When the turtle deck is installed the leather separates and closes behind tube as the turtle deck is lowered. I riveted them on.
Jim , just wanted to say thanks for letting me plagiarize ( had to look that one up in the dictionary) your idea. Finally got around to doing the mod on the stab trim slots. Hoping for some snow to melt off the strip soon , so I can see if my neck stays any warmer on a test flight. If nothing else, looks a whole lot better than the open slots. Bruce N199CL
Looks nice Bruce!
