So, I'm building my own drone and I'm thinking of using a 4S battery on a 1.5 pound or 700 grams drone. I was going to use a 3S, but it's very hard to find testing on the motors that I am trying to get. So around what kV motor should I be looking for? I've been looking at the Mini Quad Test Bench, but I only see results with 6s batteries. Does anyone know how I can look for thrust values with 4S or maybe even 3S? This is not for racing, it is for long range so the most efficient motor is required.
