R/C industry data
 

Hi All,
I'm doing some market research for my class at the University of Minnesota. I'm wondering if anyone knows of any trade associations or good sources for market data on 1) the R/C hobby market and trends 2) general R/C aircraft market and trends (helis and planes) 3) R/C helicopter market and trends. I tried calling the Radio Control Hobby Trade Association, however the number has been changed and the re-direct is just a local park office. I also tried the Crafts and Hobbies Association (CHA) and they do not track R/C hobby data. Any help is greatly appreciated!

Thank you, Nathan
