I know my 20 month old isnt rdy but i have tried to get him on G3 but not much luck there.
I did buy him one of those 20 dollar Nikko rc car, and he can actully drive it around alittle, that alone made me happy
Im gonna give him till about 2 1/4 years of age then try again.

One things for sure though he is absolutly fascinated with planes He loves it when my wife comes flying cause that means he gets to go, he trys to be my little helper
