 |
|
I've received a lot of responses about the need to have a gap seal. I guess
stall speeds increase & performance in general is severely degraded. Mine is
pretty shot. Has anyone built one that is permanent? Does not need to be
removed every time you fold the wings. Barring that does Kolb sell one or is
it usual for one to fabricate your own?
I did not like the option of having to remove the gap seal to fold the
wings... so I started with kolbs plans and modified them to fit my
application.. you can follow a link to my gap seal from this link. If you
have any other specific questions that you think I could help with, let me
know.

This one slides out, all you have to do is take two screws loose from the front.
Takes about 60 seconds. Here is the way we do it down south.
----------------------------------------------------------------------------------------------------------------
WING GAP SEAL
See drawing sheet 44. In your kit are four 1/2"x5/8"x30" sheet metal angles. Clamp two of these together with approximately 0.032 gap between the 1/2" legs and drill #30 holes with 1" spacing starting from one end for 16". Then cut metal to each of the holes so channels can be contoured to the wing.
Drill and install channels with 2" spacing to IB side of IB wing ribs with 1/8" rivets. Lay 0.020 sheet metal on top of wings and mark along each channel (I think it is 6061 aluminum –thin, but kind of stiff). Add approximately 1/2" to each side of these marks and cut (You don’t have to get too tight of a fit here).
Now cut a section of 1 112" tubing to fit between wing LE tubes. Hold tube in position and slide gap seal LE on tube and rivet in place. Cut a 1" long piece of 1 1/2" aluminum tube. Then cut out 1/4" gap, as you did making rear spar splices. Slide this piece into wing LE tube with Epoxy applied and use sheet metal screws to attach the forward corners of gap seal to wing LE tubes. The doubler makes a better thread for the sheet metal screws(drill larger hole in gap seal for screw). I did mine a little different here and just used one tube over the ends of the LE tubes that stick out about 2 inches on my plane.

Pretty slick, gotta think about that for my US (the previous owner flew
without a gap seal). I've been thinking 1/16" Lexan, but I could do it the
same way...
Is there a bottom cover too, or just on the top? It's not clear from the
pictures.

My software never has bugs. It just develops random features.

No - you don't want a "bottom cover" it just slides in and out of the tracks.
This gives you several inches for your helmet, camera, etc.
If anyone needs the "tracks" - let me know, I'll send you some.
You've gotta build the rest of it yourself, like I did.
You might notice I "sealed" the wings, just in case you might
(heaven forbid) land in the ocean or a lake or something.
Guess you've heard about the global warming thing.

I am between a wing-gap and a hard place right now...HA... I have been thinking, looking, and scratching my head for ideas on how to do a better style of gap seal (other than what is shown on my Firestar II plan-set).
My Firestar is an 96 model...I'm a little slow!!! Cauz I'm not in a hurry!!!!
I have not yet had the time to fully digest the information you have shown....but the few moments I have spent looking makes me want to jump out of my seat and say Thank you!!! Thank you!!! Thank you!!!
***I love a great idea****
Any other information on this topic will help, I have attached two digital images of my project.
