In ptulmer's defense, I believe he is trying to make a distinction between a "modeler" and someone who is just playing with a toy. A person who tosses a Toys-R-Us AirHog into the sky certainly has POTENTIAL to be a modeler, and will always be welcomed. But, the guy has to develop some enthusiasm for the hobby to be classified as a "modeler." The easiest sign is: "did he build it?" But, there are other signs:
- Has he/she purchased a more advanced aircraft and started to learn aerobatics?
- Has he/she started collecting multiple aircraft? (A SURE sign amongst all of us )
- Has he/she seeked out other modelers to talk about aircraft and see other models?

There are varying levels of being a modeler, and I'm sure there will always be disagreements on what level of effort is considered "modeling." However, my take is that any flying is potential and worth approaching the guy. If they show no interest in progressing beyond flying circles with a $30 "toy," then I think it's reasonable to say that he is NOT a modeler.

A modeler always wants to do more, wether it be building or maneuvers.
