As soon as I have verified for myself all the new ones work, I will post the supplier's(actually a manufacturer) email, so everyone else can order them as well. He sent me channel 7 27.125Mhz, and it was fine, but I want to be sure the rest work as well.

I had actually given up, because the consensus here was they would not work. However this showed up in the mail yesterday as a free sample to try. SO I did and the new channel worked fine in the Heng long radio's. Good thing the supplier followed through.
