King-X | VARIABLE HYBRID 2-SPEED PROPELLER: Get Better DESCENT & LANDING with Electric Wings in TotK @KingX | Uploaded July 2024 | Updated October 2024, 3 days ago.
This demonstrates powering a propeller with both an electric powered motor AND a small wheel! The small wheel acts as a brake against the propeller when you hold down (because the small wheel is in reverse mode). Slowing down the propeller disables the lift so you're able to descend the aircraft much better.
