I did some improvement based on issue i faced during the assembly and tweaks to my liking

• added cavity at the middle lower floor so i could hide my tiny D8 receiver and lipo beneath
• i made it a snowcat with rear bed instead of rear cab
• reduced the hexagon hole from 6mm to 5.7mm because it was rotating inside
• added 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 the Lego 3873, total 60pcs.
You may notice in the pics where one has foam pads, another doesn't.
a. Original track without foam pads - super smooth
b. with foam pads added - it's a little bit more jumpy
*tips - apply foam pads on all the tracks, if you just apply half, it's a lot more jumpy

The "front cover" is to be placed behind the "dash" with a recess at the middle for your fpv camera wires to go through.

Assembly note

1. Install the idler sprocket with its nut first! then you may install your servos. *otherwise if you are too excited like me, you have to reinstall the servo
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
5. install the remaining electronics which are quite self explanatory

Do update if there's any issue and share your makes!
