Turnigy D3530/14 1100KV

Battery: 2~4 Cell /7.4~14.8V
RPM: 1100kv
Max current: 22A
No load current: 1.6A
Max power: 315W
Internal resistance: 0.077 ohm
Weight: 73g (including connectors)
Diameter of shaft: 5mm
Dimensions: 35x30m
Prop size: 7.4V/12x6 14.8V/8x4
Max thrust: 1100g

I have 3s 2200mah batteries to use with it so maybe a ?????

I have a watt meter to test but I don't want to just go buy 10 props not knowing what I'll use so any guidance would be appreciated.

I set your specs into my motocalc software and it came back with APC 10x5 as the best choice. The motor temp was too high with an 11x5. If you do want to check out the bigger props, you should use a heat sensor on a test stand set up. While motocalc is a good tool, it is not always right and I use it to zone in but not as a final answer.
