Pylon Racing is a popular competitive sport among RC Aircraft Pilots. Because some club members have expressed interest in this sport, I will post some detail about it and how to get started.
Below, please find the basic rules, which aircraft (ARFS) are available in the EF-1 class, required motors, and battery limitations. You will also find an attached PDF of the current NMPRA EF-1 pylon racing rules.
EF-1 pylon racing is the only class that allows electric airplanes to compete. The airplanes are the slowest class among pylon racing. The EF-1 class race speeds are around 100 mph. Models must be primarily constructed of wood and covered with plastic film covering. The airframe must weigh a minimum of 3 1/2 pounds, and measure a maximum wingspan of 52″ and minimum wing area of 375 square inches.
