Tarmo3 Humvee body and upgrades

thingiverse

I thought a Humvee body would look awesome on the Tarmo3 RC car. So I took that 1/72 version from Thingiverse, hollowed it out, and mounted it on the Tarmo. The body prints in three parts with pegs and holes for easy alignment. I taped the parts together and glued them with CA - less is more. You can use either the Vertical Servo Mount Kit or cut a bit from the body to make room for the stock-mounted servo. The body mounts are a direct fit to the stock shock mounts if you drill two M3 screw holes in each of them, or you print the included shock mounts with corresponding holes. A 5mm drill bit is needed to drill the holes for the body mount posts. They sit in the middle of the grill on the hood up front and exactly on the long grooves on the tail hatch in back. I used a drop of paint to transfer markings from the rear posts to the body. Just file the holes until everything fits together. The chassis retaining clips are bent from paper clips. Since I couldn't find a good spot on the chassis for the antenna and ESC switch, I designed a mounting base that will hold both. The steering linkages were too long on my build so the front wheels had too much toe-in - I shortened them by 1mm. The main steering arm was binding at the bottom and interfering with the upper control arm, so I removed 1.5mm from the bottom of the arm, made a countersunk hole for the screw that goes into the support piece, and chamfered the top front edge to clear the control arm.
