WebMar 23, 2014 · About 0.053 N/W thrust efficiency for that prop; About 260 Watts at the shaft for that size motor; About 14 Newtons of thrust per motor; 14 newtons will hold up about 1.4 kg; Max weight for a static hover with 4 motors is about 5.6 kg; You should probably be about half this for a quadcopter that flies well, so try to get its weight under … WebSep 30, 2014 · The thrust is mass flow times speed change: T = π ⋅ d P 2 4 ⋅ ρ ⋅ ( v ∞ + Δ v 2) ⋅ Δ v. If the engine has the power P, the thrust is net power divided by airspeed in the propeller disk. To arrive at the net power, you multiply the rated engine power by the propeller efficiency η P r o p and the electric efficiency η e l: T = P ...
