Advantage of 2 receivers?
The main reason I use dual receiver's in my 35% planes and up is that I have landed a Plane with 2 receiver's in it with only 1 working saved a 3500 dollar airplane for the cost of an extra receiver. So I can not see not spending the money on it for extra security just in case something happens. Secondly as Doug says it makes it easier to hook things up without so many Y connections.
