This is an example of the mechanics for a AutoPilot steered by push pull wires. This looks like a good solution and it doesn’t have the hydrolic pump. The mechanics of our project runs by a DC motor with a gearhead, only.
However the price of this product is way above the limit compared to the price our solution should face. In order to operate this solution you must in addition buy the control box wich would most likly be another 1000$.
