▲Worlds FASTEST R/C Tracked Vehicle
Recently, rctestflight, a well-known American blogger, completed a major project of "Manufacturing the World's Fastest R/C Tracked Vehicle" with the usage of Flashforge Guider 3 Plus 3D printer. His video has received millions of views and tens of thousands of likes on YouTube, demonstrating the advantages of 3D printing for personalized manufacturing. The parts 3D printed by Guider 3 Plus showed excellent performance, well meeting the requirements of a snowmobile in terms of mechanical properties and assembly accuracy.
"I'm going to design it from scratch and completely forgo gear-driven drivetrain electric skateboard motors. They have a decent amount of torque which means they can often be used with very small gear reducers or even direct in the case of hub motors drive."
-- Daniel,blogger of rctestflight
The design and manufacturing of the tracked vehicle project was of creative customization. The tracked vehicle pursues the highest moving speed that definitely puts forward high requirements on the strength and stability of the entire body structure. To customize such a R/C snow vehicle, Daniel had to self-make all of the vehicle parts separately.
Guider 3 Plus 3D printer, with fast and high-precision printing capabilities, helped Daniel manufacture most of the structural parts on the R/C tracked vehicle, parts like braces for the drive axles, motor shields, outer profile, and wheels.

Those 3D printed parts illustrated in the picture above showed complex structures such as holes, curved surfaces, and gears. The parts to be 3D printed should have high precision, so as to ensure a good math between the brace and the motor shaft, between the wheel and the rolling shaft, between the screw hole and the screws. That’s important to assure the stability and coordination of the overall body.
Daniel selected Guider 3 Plus 3D printer and this was his first try of a 3D printer. Flashforge feels honored that Flashforge Guider 3 Plus was able to well cater for all those requirements to create structural parts needed. This Flashforge 3D printer adopts Core XY structure, printing stably at high speed and ensuring high printing quality. In addition, the flexible platform of Flashforge Guider 3 Plus allows for easy removal of the finished parts.
During the entire assembly process, the sample parts 3D printed by Guider 3 Plus hardly require any post-processing. That’s to say 3D printed parts by Guider 3 Plus can be directly used for assembly. Beyond that, parts printed by Guider 3 Plus 3D printers displayed high mechanical performance.
The driving force of the snow cat comes from two circular motors, which are important electrical parts needing protection. To meet the mechanical performance, Daniel designed a curved shell to withstand greater impact, while that was not a small challenge for a 3D printer. Eventually, Guider 3 Plus was able to ensure layers accurately positioned and fully and accurately bonded together during the 3D printing process. It not only ensures the impact resistance of the finished parts, but also ensures the smooth and delicate effect of the curved surface.
