I had a dx3 s and now have a dx4s and the dx4s does seem to reach further. The orange ones do work with it. I bought three orange receivers in a three pack for $40 shipped on eBay. Kintec sells them and eBay has them. You can use general purpose clear epoxy on them to waterproof them. I submerged one with the epoxy on it and it worked fine right after and still works. I've been using a couple of them as an experiment for a while. So far neither of those have failed me.
