That is the problem with local events. They get good local support and then someone decides to make it an national event. I have seen it thru the years, 1/2A Mouse, Class II Goodyear, Slow Combat, Shoestring/Fox racing and yes, profile carrier. So the other event pertaining to this site is P-40(profile 40 Stunt) which is being changed in other areas. What would happen if we went back to the 64 NATS and had only the national events. Speed at that time had multiple classes because of engine sizes. Of course F2C was getting started with B-Team. Free flight had multiple classes because of engine sizes. Radio had classes because of number of functions for the planes. Remember the rudder only planes flying a pattern. Back then I could go to a local contest and fly Combat, Rat Race(which was not an official event yet), Navy Carrier and balloon pop. Only two combat planes with the others in the back of my 64 Fairlane.
Now your Clown Race was a good one until the special built engines came into the picture. Hope you keep the engine requirement for the NW .40 event.
