First off. You are going to need wide radius curves. I’m assuming the coupler is removable I run Kadee’s on everything. Every pilot is different. The freight ones are the least forgiving. A Kadee #805 will couple with your coil coupler. The coupler probably needs a range of 45 degrees in each direction. Depends on your curve size. The coupler will have to be modified. A drill press is handy to get a good straight hole for the screw. Some filing will be required. The pic below shows a Kadee on the left and what it will look like when done. It may look weak. I’ve filed them even more to get more swing. Remember if the run well together there is very little strain.The modified one is actually an Atlas. I find it easier to work with as the shank is longer and there’s a little more meat. The only issue. The don’t mate with coil couplers. But are fine with Kadee’s. They do make a newer version if you can find them that are more Kadee shaped.
