I'm pretty sure you'll not find them. If they were out there the Taco threads would be ablaze with the info. You're probably stuck with AL or wire. Take a look at how Paul does his wire on the FF Taco and the Burrito. I hate wire, but these are really strong, and seem to last forever; and, they are light!
the gear is designed for a .25 control line stunter, wt abt 35-42 oz. they would run a 9X4 to 10X4 and LA 25 engine. This guy (Mike Pratt) has designed several of Sig's planes. This gear may be a bit light if you are up near 3 pounds.
