On the surface it looks like a radio problem.

I had posted about it last summer and all the "spektrum haters" ("savox haters", too) came out of the woodwork telling me do ditch my stuff and get another brand. If I had, I would have spent a bunch of money and not had a solution. Switching my ESC to one with a 5A BEC solved the problem.
