xx4 or xxx4

[footey]

hi all my dads thinking of getting a new 4wd to go with his xxx so he wants a losi but he cant make up his mind between xx4/xxx4

he will be running only indoors and he likes easy to look afterso really the xxx4 would be best for him am i right

Well the XXX4 is great for smooth track, and the XX4 is better for rough tracks. The XX4 uses a one way pulley and the XXX4 uses a one-way diff.
I recommend the XX4 cause it is a easier car to drive.

Most people lock the one way pulley and shoehorn a one way diff in the xx4.
