Traxxas Jato to E-Jato brushless conversion kit

Here is my E-Jato conversion. Inspired by https://www.thingiverse.com/thing:1581048 (conradj87), I consolidated his motor mount and created all new parts. The 3D printed components made the chassis incredibly stiff! To use the brake and reverse, you will need to block the two-speed transmission. I blocked it simply by adding small pins inside the gearbox (as shown in the pictures) and removing one gear (if I recall correctly). See my Jato in action at 26 seconds: https://youtu.be/2eAbIpnACgw?t=26 Print settings: Print the motor mount in ABS, as I discovered that using PLA resulted in overheating after about five to six runs. However, you can use PLA if your motor stays cool. The other parts can be printed in PLA. The spur gear, however, should be printed in PLA (ABS is not stiff enough). I managed to use 3D printed spur gears for approximately ten runs with a brushless 4000kv motor and a 2S Lipo battery. They are easy to replace. Assembly: You will need to keep the stock servo mount and screw the two parts onto the 3D printed front plate. No holes need to be drilled under the chassis plate. I use rubber parts from old inner tubes to secure the battery and receiver cover. There are two front plates available, one lighter than the other. Use the one you prefer. If the lighter one breaks during big jumps, simply print the heavier one. Electronics: I utilize a cheap X-car 120A ESC from hobbyking and a 4000kv brushless motor.
