Why Models are best

Traditional aerial photography used a camera pointing straight down from a very great height. This is largely because full-size aircraft had to remain very high for safety reasons.

These images were excellent for map-making, but they couldn't show the shapes of buildings and trees because only the tops were visible.

To photograph side elevations with good resolution, it's necessary to be lower and closer.

Models can do this, but full size machines cannot.

To show the layout of an area clearly and quickly, oblique aerial shots from 100 to 200 feet up are usually the best.

These views make an area look more impressive than it does from the ground, or indeed from 5,000 feet up.

Getting a camera into position a few hundred feet over an area calls for a radio controlled model.

Other methods simply don't work so well.

Models can cope with surprisingly strong winds and offer great flexibility. They are also able to take off from and land on almost any small patch of grass.
