Hope you get it sorted dude , i just put a Vess23A on mine and its awesome, real made it fly how i wanted it to.
Get some more time on her and listen to the guys here who gave you some great advise.
Here's a clip from my vess maiden flight, just feeling the prop out etc ive only had about 8 flights on this extra now.. check the landing .

Its got a 3w55i in it and still pulls out of hover well!
