Do check out Captain Disillusion's video "Quick D: Static Helicopter Blades".

Thanks to Polina for flying the helicopter all day. We hired the helicopter from VVB Aviation who were awesome. https://www.vvb-aviation.com/

CORRECTIONS
- We did also mess around with multiples of the required frame rate (53.5 fps being twice 26.75 fps) which gives a ‘choppy’ version of the stroboscopic effect with twice as many rotors appearing. But I should have taken this out of the edit as I present it as a valid solution. Sorry! First noticed by Alnakar.
- Let me know if you spot anything else!
