EAT 04 Upgrade

My ESC on the EAT04 went out so I decided to upgrade. I wanted to go brushless so basically all the electronics needed to be replaced. Motor, ESC, Receiver and Servo. The original ESC is a combo speed control and receiver and used a 5 wire servo.
The original motor had a shaft size that was smaller than the new motor that has a 3.175mm diameter, so the old pinion gear had to be drilled out. I picked up a 5900kv motor at a great price so I went with the 22 tooth gear that came with the car. The conversion was simple and the lighting was not that much work. The tail light is just a bicycle light that is rechargeable via USB and has a selector switch with 5 modes like strobe and so forth.
I extended the battery lead into the ESC so I could reach it to replace batteries without having to raise up the body to gain access. The plastic man came out to better fit the electronics and have access to the on off switch.
