I recently bought a 4320 RC unit, which came with a yellow Quartz set as printed on the back of the box.
Does anyone have one which came with a different colour Quartz set? This is the 2-part bit that chooses the signal frequency, so you can run more than one vehicle at a time without interference. One part clips into the back of the controller, and another into the receiving unit.
It's possible to buy different colour quartz sets as a direct order item (they do five in all, Red Brown, Yellow, Orange and Green), but I don't want to buy a new set if it's possible to get different colours with the initial 4320 unit, with the original unit priced at £30 in the UK, and the replacement Quartz Sets at £8.50 each.
It would seem sensible for Playmobil to offer different sets in the original boxes, and puit a coloured sticker on the box to indicate the Qartz set inside, but there's no way to choose on Playmobil's website.
