I did some calculation using similar data with this online calculator:
-custom motor with Kv=2000, res=1.6Ohm, current: 0.34A
-LiPo: 180mA, 2s, res=0.15Ohm, voltage=3.7V
-controller: Castle Phoenix 10A: res=0.013 Ohm
-propeller: custom, diam=5", pitch=3", blades=2, prop. const.=1.18, gear=1.0
-thrust=76.41g, current=1.637A, voltage=6.89V, power=11.28, eff.=45.2%
So the thrust is a little less than that of the previous calculator, but very close to it and very far from real life measurements.
Any ideas on why the big difference between the calculators and real life ?
