@donc we have this one. It's expensive, but my son saved all of his Xmas & birthday money for it and it's harder to break and easier to replace parts than the cheaper ones.
Nice. It's available on Amazon. I looked a few months ago and was put off by all the details about how you replace the different parts. I kept thinking: "Do I really want to be a mechanic?"
Years ago we had a wind up squirrel that our dog loved to "kill". Unfortunately it was no match for his teeth, and I'm unsure how safe it was. But he absolutely loved chasing it around.
One of our current dogs goes crazy whenever she sees an RC vehicle. So might be fun watching her go at it.
Thanks for the recommendation.
