Most indoor flyers that I know use STP son of a Gun for lube. You can use it straight from the container. If you use this lube before doing the double overhand knot the knot will usually not slip or tear. I've personally never seen a difference in whether the second knot is reversed or not (knot?).
This type knot is especially useful for motors where there is a weight restriction. You can cut the motor to the exact weight you want before tying. The first knot is tied and pulled as close to the ends of the rubber as you dare. Then the second knot is tied in front of it and pulled back into the first knot to lock it.

Thanks for the links,
It was easy to see why they kept coming untied after reading.
One knot foward, then one reversed seems to be working for me!
Nice, small and light.
Now to build a 35cm Tandem for practice!
Thanks again!
