I've been finding that out, many different model groups that are based on location of the Admins, the primary subject matter, how long in existence, etc. I do see the trend for the younger crowd is Tuners (for example). I joined a scratch-built model group, and then was able to see what people were into, and found it was R/C trucks mostly, which are still amazing, but I found out long ago what a money pit R/C is. I have also seen a real jet-powered SR-71 R/C plane, so when money is not limited.......
THE FUTURE IS BRIGHT, JUST DIFFERENT.
