RC Chevrolet 3100 by gamebox13

This model I got from the SpinTires Mudrunner game and edited to the 3D printing. It has 1/14 scale and RWD from JJRC Q60. Because I have a lot 4WD models, I wanted some RWD car to get more experience and difficulty on the ride.
Body printed from ABS and glued together with ABS juice. I made tyres from a silicone sealant using a 3d printed mold. It came pretty soft and heavy (because solid). I have recommended using a black aquarium sealant because it is black and has not shrink like a regular colourless sealant. Also you can printed tyres from some TPU flex plastic. I made rear wheels is wider by increasing Z scale up to 120% in the slicer for tyremold and wheel parts.

You can use any 2 channel RC transmitter. I have used Flysky FS-GT3B but also tried cheaper and more functionaled DumboRC X6
There is an old Chevy truck with rear drive and open diff. It run on the yellow TT gearbox.Original motor quickly died and replaced. Also I removed one gear step to increase speed.
623 bearing put inside the hub and may glued carefully if it loose. Hex axle screwed through bearing with M3 screw. Cup part fixed with a screw on a gearbox shaft and a driveshaft's end mounted with M2 screw & nut inside a cup. From other end you can used a metal pin from old JJRC driveshaft or M2 screw too.
Leaf spring puts on chassis with M2 screws and folded ends hold on chassis by a piece of paper clip wire.This spring's end must be slide under wire when spring is damping.
