killswitch parts sources
KILLSWITCH competitors are encouraged to build their robots using primarily scavenged parts. Thrift stores, yard sales, and local Craigslist ads are great sources for R/C vehicles and toys full of useful hardware for pennies on the dollar. Still, it's likely that all of us will need to order something, and this list of vendors is intended to make this easier.
There aren't very many places we can go to get robot parts in town, and if we don't support them, there will eventually be none at all. Just be aware that everything is cheaper online -- often very muchcheaper -- so if there's something you want but can't bring yourself to buy, check internet sources before giving up entirely.
