I got one of those wireless 2.4GHZ cameras off of ebay and it didnt work well at all in a nitro RC. That motor and the vibration made the video fuzz out completely. Looks exactly the same as the 2CoolRC cam but who knows if the image sensor and transmitter are higher quality on the 2CoolRC one.
I decided to go a different route... Take one Pure Digital camera... have it modified to use a remote image sensor... hack it down to it's smallest parts and mounted it up in a radio box so that it mounts right in my CEN truggy...
Records the video directly to flash memory that can be downloaded to the PC via USB.
