John, I am pretty sure that for the last few years Sport Scale has had the largest number of competitors. It looks like Fun is growing however. Yes, military and civilian models fly in the same event.
I was one of the static judges for Profile. I did not see the scores that my compatriot was giving, but Dick's Ki-83 was a exceptionally well done model. Hey Dick, I saw something when I looked at your model up close that I could not see in the dark armory during judging--check on the location of your elevator mass balances.
