I got my son a Maisto Rock Crawler Junior

It goes over plenty of stuff, sadly the steering could be much better. But overall not bad for under 20 quid which is what I paid
I can't wait till my kids are old enough to have a hobby grade RC. Something like a Midnight Pumpkin or Lunchbox would be cool!
