Tiny Snowcat FPV - the coolest Tiny Trak

I just got a new love - the Tiny Snowcat! Original design credit goes to Andy Anderson at this link: https://www.thingiverse.com/thing:3668608 Check out the video here: https://www.youtube.com/watch?v=kx2u_CpikNY Join our Facebook Group: https://www.fb.com/groups/181517579149618/ I made some improvements based on my experience with assembly and tweaks that I liked: - Added a cavity in the middle lower floor to hide my tiny D8 receiver and lipo beneath. - Changed it from a rear cab to a snowcat with a rear bed. - Reduced the hexagon hole from 6mm to 5.7mm because it was rotating inside. - Added a cover behind the dash. - Modified the sprocket to mount on servo horn. - Added a printable bearing in case you can't find one. The Track is made up of 60 Lego pieces, part number 3873. You might notice that some pics show tracks without foam pads, while others have them. Here are my observations: a. Original track without foam pads - super smooth b. With foam pads added - it's a bit jumpy *Tips: Apply foam pads to all the tracks, or they'll be really jumpy. The "front cover" is placed behind the "dash" with a recess in the middle for your fpv camera wires to go through. Assembly note: 1. Install the idler sprocket and its nut first! Then you can install your servos. 2. Now install your servo and the servo sprocket. 3. Pull the wires to the top. 4. Now glue the lower body and upper body together. 5. Install the remaining electronics - it's pretty self-explanatory. If there are any issues, do update and share your makes! Here's a parts list to save you time: You'll need this micro receiver: https://www.banggood.com/2_4G-8CH-D8-Mini-FrSky-Compatibel-Receiver-With-PWM-PPM-SBUS-Output-p-1140478.html?p=DG23031123036201501P I'm using a modified Towerpro SG90 for continuous spin, and so far it's the fastest servo I've found: https://www.banggood.com/TowerPro-SG90-Mini-Gear-Micro-Servo-9g-For-RC-Airplane-Helicopter-p-1009914.html?p=DG23031123036201501P I'm also using a 1S to 5V step-up module for higher speed: https://www.banggood.com/DC-DC-3_7V-to-5V-Step-Up-Voltage-Booster-Regulator-Micro-Power-Module-For-Brushed-Racing-Quadcopter-p-1092602.html?p=DG23031123036201501P I highly recommend the Fatbee FB90 Micro VTX 5.8GHz - it's superlight and a must-have: https://www.banggood.com/5_8g-48CH-25MW-VTX-600TVL-NTSC-FPV-Camera-for-Eachine-QX95S-QX105-Micro-FPV-Racing-Drone-p-1235875.html?p=DG23031123036201501P For the Frsky Xlite, I used: https://www.banggood.com/FrSky-Taranis-X-Lite-ACCST-2_4GHz-Radio-Transmitter-with-18650-Battery-Black-Caps-for-RC-Drone-FPV-Racing-Muliti-Rotor-p-1257443.html?p=DG23031123036201501P I'm also using the Fatshark Goggle: https://www.banggood.com/Fatshark-Dominator-V3-FPV-Video-Goggles-Glasses-WVGA-720p-HDMI-800X480-p-1000597.html?p=DG23031123036201501P And, of course, I printed this on my CR10 printer: https://www.banggood.com/DIY-Creality-CR-10-3D-Printer-300300400mm-Printing-Size-1_75mm-0_4mm-Nozzle-p-1085645.html?p=DG23031123036201501P
