Update 3/29/2019: V3 chassis - passive wheels are now mounted with nuts instead of screwing them directly into the plastic. It now has an adjustable wheelbase so the issue where the tracks would be too tight is resolved. Update 3/10/2019: New V2 chassis - it is a little bit more refined, it now has a magnet-mounted canopy and space to put lead in at the bottom for a lower center of gravity when climbing, designed new wheels because I had issues where the tracks would slip off the wheel. You will need: -1s or 2s Li-Po or Li-Ion battery -1mm wire or paper clips -3x8x4 bearings http://s.click.aliexpress.com/e/qYoxnJi (I pulled them out of old 2205 motors) -9g servos (2x) https://bit.ly/2UXoFqb -small PWM receiver https://m.banggood.com/2_4G-8CH-D8-Mini-FrSky-Compatibel-Receiver-With-PWM-PPM-SBUS-Output-p-1140478.html?rmmds=search -micro AIO FPV camera (optional) http://s.click.aliexpress.com/e/cYsVTXe0 -M3x8 screws http://s.click.aliexpress.com/e/bhQEMu80 -M3 nuts http://s.click.aliexpress.com/e/b1vEdSW4 -3x1 magnets http://s.click.aliexpress.com/e/Y1DKkuC Print: -Chassis_V3 -4x Wheel Bearing -2x Wheel Servo -4x Tracks or 38x Track_Link To join the track links I used 1mm paper clips. To attach the servos to the chassis the two screw tabs on the servo need to be cut (it's shown on one of the pictures). Hot glue the servos in place. To attach the two wheels to the 9g servos take the arms that come with the servos and remove the arm part so you are left with only the round thing (also shown in the same picture). The servos need to be modified for continuous rotation. All links are affiliate links.
