I think the standard cinestar landing gear has about 250mm clearance, then you can add on extenders which will give you about 300mm+ depending on what you use!
How does the 3 Axis Gimbal attach to the bottom of a multi-rotor design? Is there a screw that connects the gimbal to the bottom of the design, or are there clamps that you attach to the design to hold the 20mm pan bearings/shafts on the top of the gimbal?
