I'm having problems getting either of my controllers working with SmartPropoPlus/vjoy. Both appear to be working properly in Smartpropoplus, but in FPV Freerider the throttle and roll channels are ignored on the Spektrum DX9, and the roll and pitch channels are ignored on the Tactic TTX610. Anything I can try?

You can keep an eye on the little circles on the calibration screen. If you are able to move four of the circles individually with the sticks you should be fine. If the automatic stick detection selects the wrong circle, you can click on the one that you see is the correct one (instead of clicking "ok").
If you are not able to move four of the circles individually you might try to remap the channels to another output in the menu of the radio itself.
