Open-Source Designs by Medlin Drone

To view all Medlin Drone designs, visit us on GitHub and Thingiverse!

Not every design is perfect, or even good… but its out there, its free, I will add and update continually, and I’m learning and getting better as I go.

To implement gimbal designs you will need to generally follow this guide: Adding Servo Gimbal to FPV Multirotor

A majority of these designs are customizations of the Medlin Drone parametric design, that utilizes an open source software to allow anyone to generate a new design for ANY FRAME/SERVO combination, with no CAD experience required.

Designs:

FPV Gimbal – Universal Camera Mount

This is a new FPV gimbal design that accepts any camera via the standard action camera ‘tab’ mount. This is compatible with all existing kits and tutorials and with almost all of the existing Medlin Drone gimbal designs, mounting on the standard Medlin Drone 20mm bearing housing, and will work with analog, DJI, and Shark…

Dual-Axis FPV Gimbal

I have finally tried building and flying a dual axis FPV gimbal, with camera pitch and roll being dynamically controlled via a head tracking gimbal. I wanted to know if this would be possible to fly in acro, how difficult it would be to learn, and if it would be practical. I want to briefly…

Rotor Riot CL1 + HD1 + XR – LDX-218 – Parametric Servo Gimbal

This is a customization of the parametric design that conserves space by putting the servo vertical such that the the servo fits between all four screw holes while having them match the frame. It will fit both he normal and XR versions, the base is specific to the CL1 and HD1 as they have different bolt patterns.…

T-Motor FT5 MKII V2 HD – LDX-218 – Parametric Servo Gimbal

This is a customization of the parametric design for the T-Motor FT5 MKII V2 HD, I have chosen to reverse the drone and use the back as the front in order to not move the DJI Air Unit, but am including options for both normal and reverse orientation. My current design requires using a DJI…

FPV Gimbal – Camera Mount Options

Many of the open source gimbal designs based on the parametric design share the same 20mm bearing housing, this means that for most designs the only frame-specific part is the base, while the top/camera mount is cross-compatible between all designs that share the 20mm bearing housing. This doesn’t mean that they will all work perfectly…

Xilo JB Freestyle – LDX-218 – Parametric Servo Gimbal

This is a customization of the parametric design that conserves space by putting the servo vertical such that the the servo fits between all four screw holes while having them match the frame. I also increased the base thickness so that the GoPro clears the propellers when looking down as this is a slammed frame and otherwise…

Diatone Taycan – LDX-218 – Parametric Servo Gimbal

This is a customization of the parametric design that conserves space by putting the servo vertical such that the the servo fits between all four screw holes while having them match the frame. The current output is only for Analog/Shark Byte and a Hero 5/6/7, however bellow are the dimensions that I entered into the spreadsheet of…

On-Servo Design

I have started tinkering with a design where the top “hinge” rotates directly on the servos axle instead of having a secondary axle and linkage. This would provide some advantages if it is able to produce smooth movement but will also have some notable disadvantages, worth testing though. I created this model using the parametric…

Shen Drones Geyser/Squirt – LDX-218 – Parametric Servo Gimbal

This is a customization of the parametric design for the Shen Drones Geyser and Squirt (V1/V2/V3), for the Squirt there are no standoffs that could match the rear screw holes are just zip tied down, this has worked fine and I am yet to break a zip tie despite some hard crashes. The current output…

TBS Source One – LDX-218 – Parametric Servo Gimbal

This is a customization of the parametric design that conserves space by putting the servo vertical such that the the servo fits between all four screw holes while having them match the frame. This is working well in early testing, although a bit strange looking, nowhere near as sleek as the Ichabod V2 – LDX-218.…

Shen Drones Ichabod V2 – LDX-218 – Parametric Servo Gimbal

This is a customization/modification of the parametric design I made for the Ichabod V2. I am including a version that has a built in TBS Crossfire Immortal-T mount, as well as one that doesn’t. This is a specific offshoot of the parametric design where I removed the bearing housing and separately created a bear housing in…

Universal Head Tracker V1

This is a case and mount for an Arduino based Open-Source Head Tracker. This is the head tracker enclosure design I started with, the enclosure itself is not my design, Lee from Painless360 designed it, I only made the mount for Fat Shark, its a rudimentary design but works. This can be mounted universally using…

Parametric Servo Gimbal – Fits ANY Frame/Servo

NO CAD EXPERIENCE REQUIRED! This is a parametric design, using a free open-source CAD software called FreeCAD. With this design you can simply set the desired dimensions to customize the design to fit your frame and servo. This is done via editing values in a spreadsheet, and doesn’t require any knowledge of CAD. Step by…

Early Designs

After some early testing I started to make some changes to the gimbal designs Andy Shin had made, reinforcing the hinge and even experimenting with designs that intentionally added friction to the hinge in addition to a sprung servo linkage in an attempt to stop the servo jitters from making it to the camera. I…
