Futaba 3PKS and FASST 2.4 modules

Hi guys,

Any Futaba 3PKS users here? I just recieved my brand new Futaba 3PKS combo pack with the Futaba FASST 2.4 Ghz TX and RX modules. I have a question regarding the antennas. Now if I plug the FASST TX module into my 3PKS, I don't need the stock transmitter antenna anymore, do I? The Futaba 2.4 GHz module has it's own which takes over the duties, correct? Can I just unscrew the stock telescoping TX antenna then, or does it matter? Pretty basic question, I know, but this new 2.4GHz technology is new to me, even though I've been RC'ing for years! Thanks in advance.
