ultimately I would of thought the current method ATV, is the most reliable and cheapest method.
possible problems with a electric rc car that would need to be addressed
payload capacity
Field charging
runtimes
durability
maintenance
cost
and one thing that I keep thinking... how big is the area? because if its a really big area u might have to walk after it anyway... even just a 1/4 mile square area would be really pushing how accurately u can see and drive the car. and at that range the police might consider it a public safety hazard lol
ideally the best would be a 2014 Polaris Ranger EV. that would solve the noise issues
but the draw back is its very expensive. I would even have a look at some of the smaller electric quads... or a modified golf cart
