MARS R 用乜module 好.....

我有支MARS-R想用（收藏唔會賣）但無module....
請俾ｄ意見我, 買返Ko module 好還是2.4ghz ho.....我已有2.4g module for my EX-10.

2.4ghz = 1,350hkd with brand NEW module and receiver
if KO, i need to buy 2nd module + new 302F receiver+ new crystal = 180 + 650 + 130=960hkd
or 2nd module + 2nd ex-10 module w/ 302F & crystal = 180 + 700= 980hkd
