I put four bladed propellers on mine and I love it. I get about 5 minutes flight time with the three cell 750.

2 blade easy tune, 3 blade med diff, 4 5 6 hard to tune. Every blade that passes an arm creates a harmonic

well. you put all the props on upside down. installing them the right way should work wonders :)

My friend you should try Gemfan 2023 - 3 blades gives much better performance with almost same thrust and without DJI o3 camera shaking

You put much more weight on the drone. Light, antenna. Why do you wonder about flight time?

Where you get the 5bladed prop from?
