UH-1n Semi scale Huey

Hi everybody, this my first time posting here and I wish I can get some answers and help! I just finished building my second semi scale helicopter and this time is a Huey UH-1N or bell 212,

this Helicopter Weight 1,590 Gram with 3s 25c 3300 mah pack!!
I checked the battery and it was 280gram, the bird itself was 1310gram
the setup I have is 335mm blades, 450m stock 400w 3500kv align motor with 11t pinion,
the ESC is ICE 2 60amp,
also it has separate castle creation 10A BEC,
so I will have to upgrade the motor for getting more power to lift this heavy mass and go with 4s pack with low MAH like 2200 just to get it fit in the wood box try!
so I am between going with one of these motors: for 4s setup

Scorpion HKII-2221-2010KV 590watt

Scorpion HK-2520-3500kv 770watt

Scorpion HK-2520-1880kv motor 800watt

I need your guys help on picking the right motor for this Heli.
thanks again guys!
