etti demon motor

[sampit]

Can anyone recommend a new motor for my Etti Demon Rigger, I am currently running Etti 4960kv on 2s lipo motor but would like to go 3s or even attempt 4s for a bit of fun running SAW the only packs I can fit in for a 4s setup is
2 x 3700 MaH packs
3S just about any lipos will fit, I was thinking maybe a UL1 motor on 4s or Ammo 36-56-2600kV

they say its a 2S hull though!

2s for racing to get the run time,this one is on 3s
