Default No string to pull servo wire through wing!

I have a Big Stik 40 and my stupid ass pulled the string
out of the wing because it came loose.

Any tricks or tip to get that servo wire through the wing?

Thanks Jimmy

Tie a small washer or other small weight to some sewing thread or thin string. Hold the wing vertically, feed the weight from the servo pocket into the wing panel and slowly lower the weight, holding on to the other end of the thread. With a little fiddling it should make its way to the spot where the servo wire is supposed to exit the wing. Grab the weight with a pair of tweezers or forceps, pull it out of the wing and you have a new string to pull the servo wire with.

Agreed. A small wheel collar works well. As the saying goes, "Don't ask me how I know."

If that doesn't work for you, try this:

Go to Ace Hardware, buy a short length of transparent surgical tubing, maybe a couple feet.

Tape about 6" of tubing into your vacuum cleaner extension, and put the tubing into the servo opening or the center opening.

Don't tape up/ seal up the opening around the surgical tubing, you could collapse the wing.

Stand the wing up so the tubing is down, the other opening is up.

Put a thread (not a string, a sewing thread) in the opening, turn on the vacuum and let the vacuum pull the thread to the surgical tubing. You'll see it in the tubing when it gets there. Along the way, you'll fish the thread up & down, and feel it pulled toward the other end.

When you have thread out both openings, attach a string, pull it through, and with the string, pull the servo lead through.

Repeat as necessary. Works almost as well as the string & weight sytem, sometimes better.

Good luck!

Model aircraft 101: use your shop vac to suck a new string thru the wing.

Shopvac and cotton ball on a string works good.

Instead of string I tend to use dental floss with a weight tied to it. In fact I keep some in my flight box just in case of emergencies (never seemes to get in the way and takes up little space).  For those that fly heli's, it also works to get the belt drive through the tail tube.

Its suprising how fast a length of pull chain (from an overhead light) will find its way down through a wing.

All suggestions have been good ones but the suggestion by Brian I have also found to work very very well.

Ikeep six feet of lamp pull style metalbead chain in the shop. It is flexible and will pull itself through a wing just by it's own weight. Use masking tape to hook the servo lead on the end and pull it back through.

Obviously, this is not a unique problem. In <u>some</u> instances, I use a length if thin florists' wire. With a gentle touch, you can feel any obstruction and feel your way through the rib openings. The wire is then used to pull the servo lead.

I use a long piece of 1/32nd or 256 pushrod wire. Blue tape the lead & pull it back through.

Take the outside tube from some pushrod. Feed some string thru it, tape the string lightly at the end leaveing a loop and snake it into your wing. Take some tweezers and when you see the string loop thru the hole in the center of the wing. Grab it

No problem Jimmy
Fumblefingers here does it all the time.
Just take a small dowel (1/16 is about perfect), and tape string to one end, them work the dowel through the wing root opening to the servo opening, grab the string, unhook it from the dowel and you're in business. Or you can tie a bolt to the string and work it through that way, but the dowel's easier.

1. Grab anything sharp like an xacto knife and cut from the servo mount hole through the center of the wing, shove the servo lead down in the slashed wing, then patch the cut with packing tape and gap filling thick CA over the planked areas. Be sure to not crush too much planking/ribs when hacking into the wing if your blade happens to be so dull you can tell which side to cut with.

2. Lay the leads over the top of your covering and just tape it in place. As fuel soaks the tape loose, clean and replace as needed.
PM me for illustrative pictures.

3. Return it to Tower and say it came that way. I'll pick it up off scratch and dent in a week for another $25 off.
