ClearView implements Tx simulation and provides all curves on per model basis. Therefore, ClearView needs to read only the 4 stick positions from your Tx. ClearView generates the pitch curves (channel 6 on heli Tx) based on throttle stick position and flight mode you are in. That way, you can use any 4 ch Tx and fly CP helis in 3d mode (which normally requires 5 ch radio). As practical matter, you must have a single model on the Tx that is used for all models in ClearView. Typically, you create a new default plane model in the Tx and name it "sim" or whatever, so you know what the model is. Then, you callibrate in Windows, and after that you use that model for ALL ClearView models.
