Airplane, UAV, RC model question below.?

How far can I get a model airplane, UAV, and/or RC car to travel? It doesn't matter if it has to have aftermarket parts, like a motor, gps, and live camera feeds. But how far can I get one to fly or travel? Not considering cost.

Thank you, in advance.

I have been able to fly my uav rc airplane to 9 miles. It's required that you get a long range UHF remote module. You can get all the parts needed at UrbanDrones.com if you have questions they are very helpful and will answer everything
