I need to know if there are a cheaper model of servo motor used to create this spider.
The model of motor in this video is a HITEC HS-645MG but I found they costs about 30-35$ each. I need 24 of them to create the spider so the total cost exceed my budget. The specifics tell the 645MG is built for about 10kg/cm. I think I can use half of that power to build my spider and so save much money. The body of the spider is built in plywood, not with metal so the weight shouldn't be eccessive.
Do you know a model that can allow me to build a version of it without spend a thousand dollars?
