Anyone ever get Kadee uncoupling magnet in three rail to work on curves?

I have been converting lots of cars to three rail scale with kadee couplers.  I got a couple of the magnetic uncouplers as that is what I intended to do to switch sidings and the yard.  After a lot of fiddling I have one siding up and running.  But, when I designed my yard I started it in a curve to maximize space.  The problem is that I cannot figure out a way using the uncoupler or rare earth magnets to make the kadee couplers uncouple etc on a curve. 

Try placing the magnets on the straight track prior to the curve, then use the "delay" feature to back the cars into the curve where you want them spotted/stopped.

If Kadee uncoupling in 3-rail is anything like Kadee uncoupling in HO and N-scale, they don't do good on curves.  Unless they're very large curves, then you might stand a chance.

I think it is going to be tough to get them to uncouple with a magnet on curves, unless very broad curves.  

And the other side of the coin is that Kadee (or any other brand) couplers don't couple reliably on curves either. Even on my small simple Pike I have done a lot of  track-plan tweaks getting reliable uncoupling/coupling.
