CREATED TO DRAW people who fly Rat Racers and other Control Line Racing events into Speed, the Formula "40" Speed class is an easy event to fly. It epitomizes the virtues of simplification. There are no takeoff dollies to build and chase. The fuel is supplied at the contest. The only restrictions on the the design of the airplane or engine are that it must have at least one wheel permanently attached and that the engine displacement must be no larger than 6.6 cc (.4027 cu. in.). The fuel supplied is mixed to a standard formula of 40% methanol, 40% nitromethane, and 20% lubricant. The choice of lubricant is left to the organizers. The lubricant I use is three-quarters synthetic (K&B X2C or Klotz) to one-quarter castor (Bakers AA).
