Looks fine to me. There usually is some confusion concerning sensored / non-sensored motors and ESCs for newcomers, so i though i’d write a quick paragraph about them.
A “sensor” is a small PCB at the end of the motor that carries three hall sensors - these detect the exact position the rotor is in. An ESC made for sensored motors can use these sensors for optimizing the motor control - this often gets you a smoother acceleration in speeds between stand-still and a couple km/h. When the car is moving, there is barely any difference between a sensored and unsensored setup. Unsensored ESCs are generally cheaper and therefore a popular option when there’s a budget.
Since the sensors are not required for the motor to receive current, a sensored motor can be used with both a sensored and unsensored ESC (this is what we’re doing). However, since a sensored ESC relies on the sensors to determine the rotor’s position instead of calculating it from the motor’s current draw, a sensored ESC will usually not work with a sensorless motor.
Ok, so much for that. There is one more thing that we’ll need for the electrics: Battery plugs. The usual system is 4mm bananas, with the battery providing the female terminal and the controller having male plugs. Hobbyking uses 5.5mm on most of their batteries - i’m not sure about the male-female parts of the plugs. It looks like the battery is female for the positive side and male for ground - i’d inquire hobbyking about this.
You’ll need to solder corresponding plugs to the ESC - some like these: http://www.hobbyking.com/hobbyking/store/_2087__Polymax_5_5mm_Gold_Connectors_10_pairs_20pc.html . A fairly large soldering iron (large tip or at least 60W, preferrably 80 or 100) is required to get a good solder joint to the ESC leads. Heatshrink tubing tidies the solder joint up and makes sure you don’t get a short while driving.
I would also ask Hobbyking about the pre-set LiPo cutoff in the ESC - ideally this would be 6V for 2S and 9V for 3S. The cutoff makes sure you don’t accidentally deep-discharge the battery.
Have you considered including a battery charger in the list?
