Tiny Servo Driven FPV RC Tank - Tiny Trak

thingiverse

This miniature FPV tank is propelled by Lego tracks powered by servos. To construct, you will need the following components: - Two Lego tracks (Lego Part: x939 or 43903 - visit bricklink.com for competitive pricing) - Two continuous servos (FS90R) or modify regular ones - A receiver of your choice (the smaller, the better) - A mini FPV camera AIO unit - A 5v pololu step up/down regulator module - 1s batteries (I used tattu 800mah units) - Two 5mm LEDs (green LED headlights are shown for contrast against white glow-in-dark ABS; white LEDs are installed for use) Print the following parts: - One Frame (whole or two halves [front and rear]) - One Chassis - Two drive wheels (whole [use supports] or halves [no supports needed]) - Two non-drive wheels (whole [use supports] or halves [no supports needed]) - Two non-drive spacers - FPV camera mount The frame is printed with integrated supports. Refer to the image for removing the supports prior to final assembly. Trim the servo arm to fit into the driven wheel and attach using the provided screw. Attach the non-driven wheels using M3 bolts and spacer. If printing the wheel halves, simply super-glue them together. The Frame and Chassis snap together. Secure the FPV pod to the top of the frame with super glue. UPDATE: I ordered bright white LEDs and found it was too much light. An updated file has been posted for a single central LED. If your lights are not very bright, stick with the two. UPDATE: It appears I forgot to upload the three-wheel chassis. This has since been rectified.
