Which Mamba Monster Combo for 8ight on 4s?

[highpowerhobby]

I run the neu 1512 2.5d (2050kv) on 5 s and it seems perfect for racing .15 min on 4300mah. I do not know what run times you are looking for but this is important for many peeps and there applications . You do not mention your mah or application so if you are looking for top speed go with the higher kv. The losi 4s pack is overpriced and Heavy and big!
