How many 1,000's of guys are using dual RX's right now (and have been for several years)?
Where is this supposed problem you speak of?
You've got to start paying a little less attention to talk and a little more attention to what is proven to work.

As for the tired out arguement of do-dads being "just another element (link) that can fail", I think that is ridiculous. Every part or piece you put on your plane is "just another element (link) that can fail". If you use that reasoning, you shouldn't build the plane to begin with.

There is risk every time we take off in this hobby. This is the case if you have one RX or two. This is the case if you have a do-dad or not. All we can do is possibly minimize the risk by choosing quality components and using a properly designed system.

So we have to use some common sense and figure out how we can reduce the risk. We then have to decide if it is reasonable financially (and this will be a personal decision). We all have our own tolerances for risk vs money.

When you use just one RX in large planes, you are overstressing your RX and servos (you've admitted this already). This greatly increases your risk because a system under stress is more likely to fail. By using a 2nd RX or a do-dad, your system will now work the way it is supposed to and will not be over stressed. The risk of failure has now been lessened in my opinion because things are working properly and are not over stressed.
So using a do-dad or 2nd RX actually decreases your chance of failure in my opinion.
