I am putting together a Seagull Brand shoestring. There is a small, about 3 mm, hole in the wing panels about 8 inches out from the wing root. Does anyone know what this hole is for. No detailed instructions in the book.

Wing span is 63 inches. I am baffled.

Any help would be appreciated.

check page 25 of the manual...

I'm not sure if they're calling that an anti-rotation pin, or some sort of wing incident adjustment...
(assuming that's the hole you're talking about)

I've seen these on another Seagull model and they seem to be positioned where the wing tube stops. Haven't figured out what they are for.

ah, I suppose they're to keep the wing tube itself from migrating...

Maybe they thought they needed an escape hole for the air inside the tube when you slid on the second panel ?

Is it for the threadded mounting pins??

No, That is another hole closer to the fuselage. I finally figured that one out. Very poor instructions in the manual. I am going to take the wing to my club flying field on Sat. and see if someone can figure it out. nice plane, just poor instructions. I appreciate the replies.

well now it's a puzzle... I've got a Seagull Edge 540 and it's got neither hole...
(and it looks like they've often photoshopped out the holes entirely ... odd.)

I have seen it on the 120 size PT-19 and Nemesis.

I don't know about the second hole. It I sure don't like the locking pin set up on the wing . I'm using internal wing bolts to back up the pins .

where you setting the CG on yours ? I hear the 3-11/16" CG in the manual is wrong
