Coaxial 10x60 Propellor, 3Cell, Benchmark

The benchmark voor the coaxial 10x60 prop is a little bit suprising. Although this prop didn't perform well in single configuration it turns out that in my coaxial setup it is as efficient as the 9x47 coaxial setup and more efficient then the 10x45 coaxial setup.

For my Y6 project I need 225 grams of thrust per motor. That is 450grams of thrust per pair. At 450 grams of thrust there is ~9% efficiency loss between the real benchmark and the theoretical value.
