Will I be OK with a 2S in my CRT.5??

I plan on changing over to the castle-neu 1415 with MMP soon but if I do so will I still be ok running a 2S?? Have been considering the max-amps 120c 5400. Right now I use a 12t pinion and stock 46t spur.

All out speed is not my main concern. Would like to stick to a 2S instead of going to a 3S due to cost, weight and size.

Just want something quick, fun and with decent runtime.

Any advice is appreciated.
