The 9047 prop is significantly better, is less affected by wind and gives longer flight times.
1450 gram DJI F450 with 2212 1000kv motors on 4500mah 3s
1045 uses ~ 25 amps on hover just under 10 min flight time
9047 uses ~ 20 amps on hover just under 12 min flight time
The PIDs were tuned for 1045 props. I noticed more jello when hovering /decending, and less on increased throttle, so i figured I would try increasing the prop speeds with smaller size. I didnt expect increased efficiency, but its a win all around.
If you have an f450 on 1000+kv motors, I would try 9047 or maybe 1038 props.
