Can I take a cooling fan from an old computer, attached RC helicopter rotors to it,and give it enough downward thrust for vertical lift? Thanks.

Answer
Its possible but difficult and even if you do get lift, its going to be difficult to control as you may not have the proper items to keep the helicopter from hovering properly
Try this instead - its already being done:

I need 2 of them as i need them to be able to be attached to my RC helicopter. Anyone know where i can pick 2 of them up with there own monitor?

Answer
Sounds like you just need a wireless pin-hole camera system. Try a YouTube video search: 'RC helicopter video camera'. Many of the posters state what cameras they are using.

Also do a google search with the same words. I found dozens of results.
