I am now the new owner of a Reaction 54 with a JetCat P70 (my first jet). So excited.

I am trying to set up the radio and I need some answers. Do you guys use the second channel for shutting down the engine, or is the throttle channel enough? I read that you can set up either way. Which way do you guys do it? Pros, cons of either way?
Thanks.

More questions later.
