I'm by no means an expert on this but I just sent a ar7200bx back to horizon because the guy I sold it too was having throttle problems. It was slow sometimes to react and then once it did reach 50% throttle or more it would die out. I had just removed the ar7200bx from a new Blade 450x. The guy was real nice about receiving what he thought was a defective beastx and I immediately sent him another one. When I got the bad one back I immediately sent it to HH.
I received a call about a week later from HH, the ar7200bx was fine. Nothing wrong with it. What HH said was the ar7200bx does not control throttle. It is bypassed directly to the transmitter, so the transmitter controls throttle directly. They did say it somehow works with the governor if you have one, but neither of us used a governor. So they're sending me the unit back with a stamp of approval. The issue is in the guys TX. HH feels it may be bad pots, or in need of an update. The weird thing is the guy has had no issues since I sent a replacement, or he just doesn't want to tell me!
I'm not sure if that helps answer your question, just thought I'd share what I learned. Hopefully someone else in here might be able to shed a little more light on this. As I mentioned I'm not an expert on this stuff!
