 Posted: Thu Oct 05, 2017 5:57 am Post subject: wing center gap seal |
 |
|
I need to add the center gap seal to the (1st gen) Twinstar I'm restoring. The project came with a new, uninstalled, fabric seal with a zipper down the middle. I've already recovered and painted (latex house paint) the wings, & failed to mask off any fabric to attach the seal.
Looking at the way the seal is made, it appears to wrap around the motor mount at the top rear, and wrap around the leading edge tubes in front and extend back almost to the wing attach/pivot points on the bottom.
After a quick look around the interwebs, it would appear that several different other methods have been employed over the years, including a plexi seal offered by Kolb. I also remember comments about using aluminum.
So, my questions:
How far back must the seal extend on top? Is it worth the trouble to run it back past the front of the motor mount? What about under the leading edge? Does it help to carry it all the way to the wing attach points, or can it simply wrap around the leading edge tubes?
For attachment, should it be velcro'd to each wing along its entire length, or is it adequate to simply wrap it around the wing with attachments at the rear and under the leading edge (or at the wing attach)?
Thanks for your insight,
Charlie

I have always used the lexan gap seal and attempted to cover and block as much of the gap area that I can. MIne has a section of alum. bent to go over the leading edge tubes. I use a small bungee cord to keep it up tight against the tubes. the sides are secured to the wings with velcro. Most of the Mark III's make up a "hard" section that slides in between the wings that consists of a couple of ribs that the lexan is secured to.
The installation of the HKS presented a problem because of the location of the muffler.

I restored my original Firestar earlier this year which originally used the zipper in the middle type gap seal. I talked to Brian at Kolb and he assured me that their new Velcro on gap would work just fine. I took his advice and had Helen at Kolb make me one . It was extremely easy to install and works great. I also built a Twinstar many year ago. This new one would have great on it. That just my experience, I like easy and availability. I’ll attach a picture

Well shucks; more to contemplate. 
Looks like either option requires velcro, so I'll get a roll of wide stuff on order while I contemplate materials.
Thank you for the pic, and the ideas.

The one inch will be plenty. When you get ready to take which ever gap seal
you decide on, get yourself a couple strips of Lexan and slip it between
the two halves, and it comes off nice and easy.

Great! one inch is easier to get, cheaper, etc. I like the separator idea, too.

I went back to an aluminium gap seal after my cloth one shred it self. You can kind of see it coming apart in this screen grab form a video.
It was made of the same fabric as Quicksilver sail cloth. The Lexan would be nice as well.

Looks good, and relatively simple to do. The fabric just looks difficult to keep properly tensioned, so I think I'll try either the plastic or aluminum sheet.
Is your Lexan standing up ok to fuel exposure?
Thanks for both the info, and the pics.

If you get gas on it, it will be ugly. There is compensation in that my neck is so stiff that I can't see it when I am sitting down and I am old enough to forget that there is a problem quite soon after sitting.Larry

I hear you. Sometimes my wife has to remind me about what I'm working on.

Is your Lexan standing up ok to fuel exposure?
Thanks for both the info, and the pics.

MIne has a section of alum. bent to go over the leading edge tubes. I use a small bungee cord to keep it up tight against the tubes. the sides are secured to the wings with velcro. Most of the Mark III's make up a "hard" section that slides in between the wings that consists of a couple of ribs that the lexan is secured to.
The installation of the HKS presented a problem because of the location of the muffler.

Looking at the way the seal is made, it appears to wrap around the motor mount at the top rear, and wrap around the leading edge tubes in front and extend back almost to the wing attach/pivot points on the bottom.
After a quick look around the interwebs, it would appear that several different other methods have been employed over the years, including a plexi seal offered by Kolb. I also remember comments about using aluminum.
So, my questions:
How far back must the seal extend on top? Is it worth the trouble to run it back past the front of the motor mount? What about under the leading edge? Does it help to carry it all the way to the wing attach points, or can it simply wrap around the leading edge tubes?
For attachment, should it be velcro'd to each wing along its entire length, or is it adequate to simply wrap it around the wing with attachments at the rear and under the leading edge (or at the wing attach)?
Thanks for your insight,
Charlie

Hi all,
I have one of the first Firestar’s and that gap doesn’t prevent me from flying without it. In fact since it is not part of the wing or fuselage I would not want to depart into my prop. Don’t ask me how I know that. I have wondered how others deal with it.
