Tricopter conversion for ZMR 250

prusaprinters

<p>This item is designed to allow converting a zmr250 style frame from a quadcopter into a tricopter. It includes a slot for one 9-gram servo and a place to attach your motor.</p> <p>Make sure to print all parts on their sides so the part that looks looks like a comb is flat on the table. This gives the maximum strength in the weak area where the hinge is.</p> <p>I used MIG welding wire as the servo connecting rod and for the axle. A dab of hot glue holds the axle in and keeps the whole thing from falling apart. For attaching it to the frame, I used some plastite screws salvaged from an old NERF gun. 3mm machine screws might work but plastite is preferred so it grips the plastic better.</p> Category: R/C Vehicles
