now from my limited knowledge what i know that a module radio such as the futaba 9C allows you to change frequencies....compared to having one set in stone unless you send it to them with the 7C...now where i plan to fly is VERY busy (Markham park in ft. lauderdale)...so wouldnt i be better off w/ the module?

what other benefits does it have?

what other benefits does the 9C have that the 7C doesnt?

just want to know if its worth the extra $100.

Edit: if this belongs in the radio forum (thought i was there) can someone please move it?

Thanks

Chad
