250 size Multi rotor build

I recently put together a new 250 size multi rotor from some parts that I had lying around from an old multi rotor I had built a couple years ago (It was a knuckle H quad) I got a flexybee frame to put the electronics on and sadly found out that it no longer flies due to the motors now being too weak. I am running a 3s 2200 LiPo, 15 amp multi star ESCs, turngiy park 300 1380kv motors, and 5 inch props. Fully loaded it weighs 819 grams. Currently it will not even liftoff the ground. Does anyone have any suggestions on how I can fix this? New motors or something? Any help would be greatly appreciated.

-Thanks

Yeah, you nailed it. Those motors work best with 8" props or so on 3S. For 5" props, you're going to want something around 2300 KV.
