Joel,

Can you estimate the scale and size of the gyro on attached photo?
You can fly big machines or small machines, the important is to fly the model that is the good compromise between your possibilities (money and distance to fly, pilot skills...) and your dreams! If the field is too far, small electric can be the most convenient solution (unfortunately, flying field are often far from modeler's houses). And the pleasure is not only depending on the gyro size!
