You say especially when its a bit choppy. Sounds like a loose contact. First of all I would check all connections.

Or is it about venting the prop?  
For me the change to the foildrive 3 blade prop changed this.

What are the motor current settings? Can you read errors via the remote control or have some sort of logging?  
For your ESC check if they recommend keeping on the slow ABS.
