Dont feel too bad but need to work out why my drone now heads to the ground very quickly though everything spins up fine
More blades = less efficiency... so yes a single blade is most efficient.
The need for tri-blade (and beyond) is to reduce overall disc diameter for the needs of the design such as ground clearance or placing wing mounted engines closer to the fuselage.
Saying they work really well in high winds has no technical merit.
Two, things, glad its fixed, thanks for posting what your results were, good or bad!Thanks joint effort. Experience speaks volumes over hear say so I do appreciate it.
And Rod.... I owe you a beer.... drone is back to its working self... the tough little bas***d that it is!
