Turn Coordinator

I did a really nice TC, and it works fine, but I used: execute_calculator_code("(A:Delta heading rate,rpm)", &rpm, NULL, NULL);to get the rate/min. Now, I'd prefer to just use the appropriate C++ MODULE_VAR, and so I tried these: DELTA_HEADING_RATE TURN_INDICATOR_RATEwith the later seeming to be a newer addition. I could not seem to figure out what units the later was in, and also am not sure that any of these simulate a canted turn coordinator vs. a turn & slip.On the plus side, the ball was easy, although as we know from previous posts not realistic.Which of these is best to use when trying to simulate the canted variety that senses roll and yaw? What units are they in?
