Thanks for the help DB. I understand so far what you said. But one more thing puzzles me.

If you still need a different rx, is the comp tx able to change frequencies to match that model? Then you choose the frequency of that model to fly?

Or does the tx remember the trim settings associated with the number that is set to the particular model? Then you just set the tx to the number of the model to fly (with all trims saved in the tx). Then just go fly.

Actually.....I think that's it! Tell me if I'm understanding this correctly (anyone).

Thanks,
