i had a cheap 70 dollar wireless camera that i had got from ebay a while back. Ran off of a 9V battery and didnt have that great of range. Always had static and being on an electric car didnt help much either.
But i found this in my ama magazine last month and im going to give one of these a try. Only a 100 bux and its digital memory recording and charges off my computer usb port... cant beat that
I have a few gas giant scale planes i want to use this on. And an electric bi-plane foamie.
Only wireless cameras ive actually seen in any plane and have a clean and clear picture and signal is the ones that are 2-300 bux.
