upgrading the motor on a parkzone P-51

[HeliScRapYard]

Hey, I am looking to put more power into my parkzone p-51. I have two ideas so far. I have weighed the options and this is what I have so far. I am asking bc I know I could throw in both and get it to fly but I would like it to fly well.

Option one, is a power up 480 speed 1400kv from heads up. Will require a 2200mah pack. This option adds 2oz to the total weight. The motor is the same weight.

Option two, is a turnigy 35-42 1100kv the motor is 1oz more and with the 3s 2200 it adds a total of 3oz. Mainly the only reason I am upgrading is to go faster. And I can use a 4s 2200 which brings the additional weight to 5oz over stock.

What do y'all think? I don't know a whole lot about wing loading so I thought I'd ask.

Thanks in advance.

OOk well.. I went with the 35-42 so that I could run it on 4s if I wanted. I reversed the shaft and it went right in. I had to cut off about 1/4" off the shaft but now it fits perfectly.
