[Lab] mario kart shell

[Paul & Andrea Mumby]

I also recently broke down the electronics costs as well, based on all hobby
gear from hobbyking (rather than splitting it up as per his electronics
document) cost is a little more, but more convenience (and it's likely
overkill for this application). Also some of the parts he calls for in his
doc are no longer in stock.

ESC - $25 -
http://www.hobbyking.com/hobbyking/store/__14634__Turnigy_TrackStar_1_10th_Scale_60A_Car_ESC.html
Motor - $13 -
http://www.hobbyking.com/hobbyking/store/__15185__S2445_3200_Brushless_Inrunner_3200kv_.html
Battery - $14 -
http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=8912
Servo - $3 -
http://www.hobbyking.com/hobbyking/store/__662__HXT900_9g_1_6kg_12sec_Micro_Servo.html
Radio - $20 -
http://www.hobbyking.com/hobbyking/store/__12177__HK_300_3_Channel_2_4ghz_FHSS_Ground_Radio.html

All in electronics cost: $75 (plus shipping from china)

I'll be buying at least one set or two. And I know a couple others might be
interested. So if you like we can do a combine order for parts for a bunch
of these to save on shipping cost.

Let me know.
