I was just thinking. You are saying you could buy another spektrum rx but you're worried it won't work like your first one. Maybe if you can find a rx at another shop you can see if Horizon will pay for it, that way you can get a quicker replacement. Or maybe they can reimburse you if you pay for it. That way even if it doesn't work you won't be even more "invested" in this new technology.

Hope this helps
