For what it's worth, I tried one of the Estes red plastic adapters yesterday for the first time. I put an AT 24mm E15 in the 24mm-29mm adapter, and flew it in a Trajector. In addition to being nicely designed and very easy to use, the adapter suffered no ill effects whatsoever. It looks perfect and ready to fly again.
Somehow I had expected the two halves to snap together, but eventually I realized there was no need or purpose for that.
