Those little RC cars, boats, and planes are cool. But ehh I grew up I prefer to play with the real ones now.
One of my uncles has a truck like that he drags out once in awhile. Amazingly fast. We usualy drive it around for half an hour or so until something breaks or we get bored.
If you build like a 5ft jump and hit it just right they really fly! But thats how you break stuff.
