The Scout is a micro tracked FPV Rover using all snap-together 3D printed components and SG90 servos, making for a cheap and versatile platform for hobbyists. The cab is designed to resemble a full-scale “snowcat” type vehicle, with scale features such as 5mm headlights, doors, and exhaust. There is a large truck bed, allowing large batteries to be strapped down via velcro straps, with plenty of room under the bed for electronics.
The Scout can be used with conventional hobby radio equipment but was designed to utilize an ESP32-CAM module, which is designed to fit in the cab and provide full control and FPV feed to any computer or smartphone. Arduino sketches are provided, so configuring an ESP32 yourself is as simple as upload and go.
Once the Scout32 is running, connect your phone or PC to the wifi network “Scout32”, and enter 192.168.4.1 in your web browser to load the app.

Required to complete the kit:
You will need a battery, voltage regulator, continuous rotation SG90 servos, and ESP32-CAM OR receiver of choice. For reference, I have made an Instructional Video which describes both ESP32 and hobby receiver builds.
All parts are designed to print with a 0.4mm nozzle. Servo spline on drive wheels may require printing at a lower speed. If fit is not correct, drive wheels may be scaled +/- 1%.
Some parts are print-to-order – Please allow a few days for shipping. Alternative colors may be requested.

Tracks & Chassis
Tracks are printed in TPU. I use a fairly stiff 95a shore hardness. You may be able to use softer TPU with varying levels of success, but most printers should handle the 95A without issue. I use PLA for the chassis, and have had great quality prints with the brands below.
