Goku,

MOST combat meets don't use 1/12 scale planes. The most popular class right now is called Open B, where the planes can be any design you want, within some limits. You can read the rules at http://www.rccombat.com.

Another class is SSC, slow survivable combat. You can also see the rules for this class at http://www.rccombat.com.

Scale combat is dying a slow death, because people simply don't want to spend days building a beautiful scale plane only to have it shredded in a midair collision. Most Open B planes and SSC planes can be built in a few hours, and are much more resilient. If they are damaged in a midair, they can usually be repaired quickly. In fact, I flew out of two Open B collisions last Saturday, and none of the SSC collisions we had were fatal.

Maybe you should work on getting Open or SSC combat started in your area. The guys flying scale will have a lot more fun if they aren't squeezing their sphincters every time two planes come within 30 feet of each other.
