When switching to different airplane models does the 16SZ also automatically switch to the system that was programed for each model? For instance if one model was programed for the Fasst system and a different model was programed for the Fastest system.

Yes. All model data, including transmission protocol is in the model file. No need to make any changes when switching models.

Thanks. Certainly answers my question. I'm upgrading from a 7C 2.4 and have a bunch of models on R617FS receivers.

617 is my personal all-time favorite RX. I still use them.
