Infill: 15%

Track: You'll need 64 tracks. Infill: 15%

Pin: There are two different pins. The normal one is 3.7mm. If the chain is to tight, you should print the small one with 3.0mm and add 3-4 of those pins. After printing the pins, you have to remove the small support on each side. Infill: 15%-20%

Small cog: You need 8 small cogs. Infill: 15%

Main cog: You need 4 main cogs. Infill: For the first 10mm you can print it with 15%. For the rest you should use at least 90%.

Rubbertrack: Use Flexifil or Ninjaflex for the rubber track and glue it to the track. The rubber tracks are not necessary but you will love it. Infill: 30%-50%

Track2: If you don't want to print the rubber track or don't have Ninjaflex, you can print track2 instead of track + rubber track. Infill: 15%

Front + back: Print this with brim if it doesn't stick to the surface and use support structure. Infill: 15%

FPV-Cam holder: Print it with support structure and glue the small part on the back side. This is for the servo to move the cam up and down. Infill: 15%

Camera and LED mount: You need these two parts if you want do use a fpv-camera. Infill: 15%

2x package of 10 bearings 688ZZ for the small cog (you need 2 bearings each cog)

1x package of 5 motor with gear (you need 4 motors, 2 for each chain)

2x brushed esc (one esc for each side. connect two motors to one)

8x bearings 61802 2RS / 6802zz for the main cog (each main cog needs 2 bearings)

1x Infrared-camera (or a normal one)
Caution!: To use the infrared part of the camera, you need a two-way-switch (link coming soon)

1x Infrared-LED (if you do not use an infrared-camera, you don't need this LED)

1x Power-supply for the infrared-LED (if you do not use an infrared-camera, you don't need this)

1x Rear camera

1x FPV-switch

1x Package magnets (front and back are sticked to the frame by magnets)

1x fan 40mm for cooling the vtx

1x servo for the tilt-mechanism for the cam and LED

We use 4 tuning motors (Slotdevil 2035) instead of the motors which come with the gear reducer. You can run the tuning motors with 3S (the ESC does supply this, even if they are for 7,4v)

Use 4 motor pinions for the tuning motors (sigma 4 9z m50 nylon)

The Brain for the FPV-Rover
OSD PCB with sensors and usefull stuff for the FPV Rover

The Rover-Brain is complete PDB with integratetd OSD, BEC, Current Sensor, Voltage Sensor, RSSI Filter, LC Filter, and 3 Step Switch. It´s to keep the FPV-Rover Clean of a wire mess and to have all necessary information of your onboard system in your Video-Downlink.

The first upgrade for the FPV-Rover is ready.

The second upgrade for the FPV-Rover is ready.

The third upgrade for the FPV-Rover is ready.

The fourth upgrade for the FPV-Rover is ready - designed by Superfly851.


Added a mini version of the rover

Added top without vents. Use with caution!! Might determine damage to your electronics.

Added another upgrade by Superfly851. The Grabatron

Added another upgrade to the rover, so that you can mount a GoPro to the top.
You have to use the new top plate with the two holes on the front side.

Redesigned the top so that you have less support structure
Added some pins for the track with different diameter. Please try at first which one fits best for you
Modified the tow-bar a little bit and added another part for connecting the trailer to the rover
Added a new link to the 6802zz bearings
Added a new link to the micro servo for the tilt-mechanism for the camera
Added two new videos
Added links to the part on tinkercad
Modified the inner track frame with B and F (back and front) so that you don't screw it up
Added some parts you need (Screws) to the list
To use the infrared part of the camera, you need a two-way-switch. (link coming soon)
Pins for the track now in single files
Due to some request, I've added the bodies without the manual support on the bottom. So you can decide which one you will print.
