These are great value if you want a new all in one rc car.
My 3yo had a Grasshopper and loved it, it was quick and now he is 5 he has a 540 motor in it and he still hasnt brtoken anything on the car.. Plus his dad can mod it.
My daughter is now 3 so she also will be running a Grasshopper (although she wants a pink one..)
