electric motors for models

a long time back there was link that provided a " how to" on putting one of those electric motors in a model car to make it roll and stuff, but now i cant seem to find it. The site also offered kits for sale that included everything you needed to get started as well. If anyone knows the link to the site im talking about (i forgot its name :(, sorry ) or a similar site please let me know, the "how to" portion of my request is more important to me.

U can get the instructions here, www.tinyimports.com

Thats the site! I couldnt remember the name (alzhiemers:confused:) thanks again!
