2.5 inch/63mm propeller comparison - Gemfan, HQProp, Nazgul for Cinewhoop

[@alchemist_fpv]

Thank you for doing this. I have been trying many different 2.5" propellers on my O3 cinewhoop and I have found the gemfans to be the best balance between power and efficiency. Your test seems to confirm that

Yes I agree, not the highest thrust but a good balance between thrust, efficiency and noise
