RC Tractor Pull Challenge (5-pack) with Pulling Sled

I give the kids very little instruction with the tractors besides the basics – you know, so they don’t break them. But then I just tell them you have to make a tractor that can pull the most weight the farthest and they have to figure out the gear ratios, the tire sizes, the hitch placement, all through trial and error. It’s a really good tool for kids to learn by doing and if they make a mistake, figure out ok, why didn’t this work and what can I do to make it work better. And when they can compete, they’re a lot more engaged.
