Neu 1512 and Medusa 60mm are for 1/8 buggy even some truggies, 1515 is for MT's and some truggy setups and will be just fine on a 1/5 2wd buggy with the right motor and voltage, though the 1521 would be better. The 70mm medusa is too small sorry, but the 80mm should be fine.

Neu
1515 - 1500/2700watts 30sec
1521 - 1700/3000watts 30sec

Medusa
70mm - 1100/?30sec
80mm - 1300/?30sec

My vote is for the 1521 1y w/ 6s lipo, that would be more than enough, if he was to use a 1515 or medusa 80mm he would need low kv and HIGH voltage 10s-12s range and a very expensive ESC to meet the demands.
