Wheely king motor choice

Hey guys, I am building a wheely king. I have decided on most everything but the motor. Right now I have a 13 turn flat wire motor which is great, for the 10.25" WB. I was almost set on my motor choice until I decided the WB needs to be 13". Now I was going to get a medusa 4800 kv motor with a 5mm shaft, right now I run on a 6cell in the stock location and thats why I decided on such a high rpm rating. Now I came to ask you guys if this would be a decent choice or do I need something more powerful? I should also add I will be using maxx sized tires. I also was wondering would this motor hold up on 3s?

I was also considering the Feigao 380C 9t which is slightly over 4300 kv I believe, I think I will get that one today if it will be fast enough. I definately like the price because then I can order other things today to get the truck rolling. Sorry if I am flipping subjects too fast, im antsy.
