The only places I KNOW say anything about spinners being required are... RC combat needs a rounded spinner-nut or a spinner. And Pylon racing has a similar requirement...

Maybe they are confusing the giant sacle pylon requirements with the requirements for sport or aerobatic flying? DuBro's listing "meets AMA requirements" on their spinner-nut packaging has led to some confusion... some people THINK every plane has tohave some such device.

Even the D-VIII Education Coordinators [&:](husband/wife team) tried to tell me I HAD to have a spnner on a sport-aerobatic .40 size airplane to fly it. (I told them to read the rules.[>:] They didn't talk to me again for 4 months and they belong to my club.)

If its ABSOLUTELY required any time that sze airplane is flown... (and its under 55 lbs..) its in the safety code.

If its over 55 lbs... look in the overweight waver sections and in publications, in the membership manual and competition regulations.
