The above Thread should answer all your question. Please review the last post by Gunner as I forgot to include a very important step in the setup.
Also, certain receivers may react different to the setup so you may have to switch channell 7 and 8 around to make it work as mention.
If the above thread works for you please post your results on that thread or move this thread over there for continuity.
Later I will incorporate / edit the steps and solutions that work. As of now, I do not have a GV1 so I cannot verify the setup. Thanks.
