I recently had a similar problem with a frsky v8fr-II that I bought from HK. I have not figured out the exact problem yet but I have lost signal 3 times over the last few weeks. One time destroying my airplane. It has happened after about 7 minutes of flight every time and usually when I am flying slowly. The rx is inside of the foam fuse but with my esc heat sink outside the fuse it may actually transfer cold into the fuse. When I fly faster, the battery gets warmer and may warm the rx. I will try and do the freezer test with my rx and see if it is like yours.
