Was wondering if someone was going to ask that. Answer is no. Used them on another project that I had.

Went shopping for new ones when I built the heli, and my primary concern at the time was to get ones with holes spaced so that the link rods are parralell to each other. So I bought some standard white nylon ones. Looking at what happened, bad idea.

Not going to use those ones again so I will go shopping for some of those proper black thick unbreakable ones I got with the servo's.
