The 1512 is a shorter can than the 1518. Shorter can = less torque. They are both rated at 1800rpms / volt with no load but the 18 is more suited for big monster trucks like the ERevo or other 1/8 scale vehicles. The 1512 is for a 4x4 SC or 1/8 buggy. Either will be good on 4S but depending on the size of the track 5S may be better.
