Does anyone know of any statistics relating to how many people in the world currently fly RC gliders? Or in which countries it is most popular (either in total numbers or as a percentage of population)? Anyone care to hazard some guesses??

Being an Australian, I'm personally particularly curious as to how many RC glider flyers (or flyers of all types of RC aircraft) there are in Australia....

I hope some of you can help satisfy my curiousity and perhaps others might find it at least a little intriguing as well.

Regards,
