Quad motor control using R/C signals and remote with Arduino

Thank you for the response. I was afraid my topic would die.
But anyways to address all of your questions..

  1. 4X 6 volt DC MOTORS - Mainly the hobby style link here -> http://www.sciplus.com/singleItem.cfm/terms/16337/cartLogFrom/froogle

  2. Information for this question is answered in the link above

  3. I was thinking about using this http://www.google.com/products/catalog?hl=en&safe=off&client=firefox-a&hs=a0D&rls=org.mozilla:en-US:official&biw=1280&bih=555&q=rc+helicopter+controlle&bav=on.1,or.&um=1&ie=UTF-8&cid=13136286476430826164&ei=AuReTaS9McWclgfU3cTqCw&sa=X&oi=product_catalog_result&ct=result&resnum=1&sqi=2&ved=0CHQQ8wIwAA#

or buying any RC toy and stripping the rc receiver from there and using it with my Arduino. or is there a special "shield" for RC signals?

Thanks for taking your time out to help. I'll keep you updated along the way. =)
