Just an example to compare. 7559 yen VS 6300 yen for the 2.4 GHz module. I'm sure there're shops cheaper than Pro Shop but as an online Japan RC shop that know English, reply emails same day & ship goods same day or 2nd day after paid, they're great. Sure Hong Kong RC shops are cheapest & they're always my 1st choice but some parts they don't carry like my favourite Kawada parts, Squat & those Atlas wheels.
RC Champ is the cheapest over these 3 shops but I don't have luck on them. They relpy email so slow, sometimes takes 2 days sometimes takes a week I have given up to order from them long time ago.
Hey, any brothers may have tried other shops besides these 3 ?
