Adarsh,
I'm afraid I have to recommend a better radio. I don't have any experience with the JR 8103. Your Rookie demands a better radio with mixing capability. Something like the JR 9303, 10X or a Futaba 12Z or 14MZ. Compare your radio specs with what's available at Horizon or Tower Hobbies. This jet has a lot of functions and with the list below as an example; do you think you can use your 8 channel radio for all these features? Matchboxes help too.

I know of another feature I added, but you'll have to search RCU to see what I did.
