@MrGreywolfcherokee Hahaha, pornpropellers! Umm, you have to ask the person who made this video :)

@ingareinar007 is this a promo or a porno...i mean the cheesy background music made me think of badly shot 70's porn.

is this a promo video...or a porno video...that cheesy music in the background...made me think of badly shot porn from the 70's.

What's with the sexy music.

How many blades depence on several things. On average, three or four blades is the most effective propellers. This is a relative small "monoblock", with high number of rpm i guess. But like submarine propellers has often 7 or 8 blades. That is less effective and cost more than your neibourhood. But they are stealthy! More than four blades gives less thrust. Ofcourse, the lighter the propeller is, the more the demands on the anomoly between all blades. Oh, I have no sound and bad Enlish, sorry)
