IMO...LOL
The 2000kv/3s combo compared to the 3900kv/2s combo has better power and run time - HOWEVER - I reckon the 2s set up is the better Bang for $ set up.
The motor is cheaper - the 2s batteries are about $15 cheaper than 3s - so the initial set up cost is less - the battery investment is less - the overall maintenance cost is less.
I also feel that a 27mm prop diameter, run with the 2s, is better suited for a narrow 160mm wide hull - a 30mm diameter prop, suited for a 3s, will have far more torque rotation, rocking the hull. The 2s batts are lighter -achieving better forward CG - less hop.
I run the 2s set up in my board #3......... average 15 minutes run time......good speed and power.....BUT.....keep it under 2kg's - 1850 grams is spot on.
