Lol.... same with me.. they send me the wrong shift for the JR... they said it a JR shift reciever.. .but maybe it not compatible with JR radio.... should I say they're idiot? or stupid? they said it has a J on it meaning it a JR shift... I don't see no J... i mean and they told me to send back to them for return.. and what... they all the way in HK... shiping charge already match the price... going to keep it and sell it later to someone need for futaba... a lesson to be learn..
