Q&A on Argos website state the frequencies used, so seems this version is not wired? Amazon box image shows 25m radio image
From what I can tell looking at these on different websites, there's a cable running from the bonnet to the controller, so calling them 'radio control' is a bit cheeky. Also it's McLaren not Maclaren, but Argos made the same mistake.
Unless they offer different frequencies (?) having two could be fun!
