Thanks for the input guys. I now own both systems. I just need another 3pk for the spektrum as i'm currently using the fasst system with this 3pk. I have sent my spektrum system in to horizon for service/replacement and when i get it back i may just get another 3pk for it. I know it's overkill, having a Sensor with two transcievers and 2 3pk's one with fasst and one with spektrum pro, but what can i say...i love the technology. But now that i hae all 3 systems, i can do some of my own testing and report on which i like the best.
