It's a big difference and the 9202 is considered a bit of a bum servo.
Since using JR digitals I've had a totalrethink... all I have left is some 6x futaba 9303's which aren't to shabby. But boy Im impressed with these JR digitals...nothing can compare.
I run all my servos almost maxed out. I say almost because I've have had some Futabas and a 7000 super servo lock out a max deflect (not fun) it's never happened with the dig's.

Servo choice is difficult so I work on a simple priciple. Simple aeroplanes have the simplest/cheapest available. Expensive/complicated aeroplanes the opposite.
