Is there a difference between a Volkswagen beetle & a Porche 911? Speed & handling. The digitals are much faster & more precise. But speed costs money,-- how fast do you want to go?

Yes the JR set is really good. Do yourself a favor & get a Futaba GY401 gyro & set it up for A digital servo.

BTW you will be amazed at how well the Trex flies!!! Probably won't fly your blade anymore.

Good Luck
