And when you install those high torque steering servos, you NEED the end point adjustment you get in the better radios so that servo isn't "grinding" at full steering lock!

You can also use the "extra" model save locations to setup different settings for the same RC. You can have one for fast, open tracks with less steering and another for twisty tracks where you need more steering D/R. It saves changing the settings each time.

The no crystal swapping for racers is the big thing!
