Make it Real: Grappling Hook Winch ( BUILD)

It s finally done SUBSCRIBE to see the final test Building steps (expand the description): We got 2x 2. 7kW motors 2 ESCs batteries and a servo tester from HobbyKing We designed the system and then machined the parts using our Tormach PCNC 440.

The rope wraps around the drive spool and an idler spool, 4 br, br,
