I am looking for a source for 3/4" diameter wing tube that is 12" long (both parts, aluminum tube and the fiberglass tube that goes in the wing). I purchased some of these wing tubes from Gator RC products years ago.

My local hobby shop doesn't have much call for these items.

I get mine here. http://www.industrialmetalsupply.com/ This is local here in So Cal, but I am sure Wichita must have a place like this, with the kind of aerospace industry they have there.

Thanks Tukkus....exactly what I was looking for, Time to get building!

Hi Fred,
If you don't come right, make you own, here in South Africa, you don't find them they are luckily easy to make. Get the pipe you diameter you require, wrap around a 4" wide piece of plastic at a angle beginning to end and tap it in place with masking tap. Backing to heat shrink covering works well. Make sure the tube will be more then you require. Then wrap fiberglass cloth / Tape the same way as the plastic, brush on epoxy resin or K&b Resin over this then leave it to get hard. if you want to get ride of extra resin, heat the inside of the pipe with a heat gun the resin will thin, and can be dabbed off with kitchen toweling. wait for it to harden, score a line round the masking tape area to expose the plastic, you should be able to remove the plastic. giving a you a 100% perfect fit tube with no slop.
regards
Sean

Troy Built Models sells all different sizes wing tubes. Not only that, but they sell carbon fiber wing tubes. I've seen airframes saved before because they were using carbon fiber wing tubes instead of aluminum. [link]http://troybuiltmodels.com/newsite/planeacc/wingtubes/wingtubes.html#inches[/link]
