I use CA or balsa cement for these things. Trick with CA is making VERY good joints and using very little. Come to think of it, that's the trick with balsa cement too.

If by wood glue you mean Titebond or Elmer's white or yellow woodworking glue, I personally have trouble using small enough amounts and don't have the patience for it to dry.

I use elmer's yellow woodworking glue, and i usually don't have any issues getting a small enough amount on it. I put a dab of glue on the piece, then wipe off the excess to leave a thin film. Because it is less dense, it adds very little appreciable weight gain and is much less fussy than superglue.

But it takes soooo long to dry :( But yes, super glue can be frustrating at times. Does anyone know if any local hardware stores sell ambroid cement? I'm tired of paying 10 dollars ship and i honestly don't think that stuff is worth it....

Really? It has never taken that long for me, and I end up unpinning most of my rotors and pieces within 10 minutes of gluing it.

Yes, but it has taken superglue longer to dry than wood glue does... at least for me

I use just a touch of accelerator on some of my un-load bearing joints. It sets the super glue in under 2 seconds, almost as strong as it's ever going to get. Plus in competitions, if something breaks, you can put a drop of super glue and a drop of accelerator.

Super glue is great for competition, but not really for building IMHO

ALL the glues can work, which is best, depends as much on what works for you. I'll refer again to a long article on how to use glues and make good joints on the NSO website, under the Helicopter Duration event, its the first resource listed.

spray blue looks like it works really well. Almost no appreciable weight gain. How does it handle though? I know with superglue, I only go two segments at a time. Do we have to attach the whole thing when working with spray?

It dries slower, so there's time to adjust/reattach the edges to make it nicer. You don't have to attach the whole thing at one time, but there's really no reason not to.

Mhm, in my basement (basically I covered my floor with newspaper and set the rotor down and sprayed it. yeah). I bought the 3M Super 77 stuff illusionist recommended, and as long as you aren't spraying for very long, I don't think there's too much of a hazard with the fumes and such. Plus it's cold outside :? :lol:

chia's approach is pretty typical, short sprays mean less weight gain, less exposure, not a big problem, though I'd be a little concerned about open flames in a basement. I do mine in a bedroom.

And cover the area WELL, that stuff makes a mess everywhere and the glue floats farther than you expect.
