There are several classes of CL Racing, but the idea is the same for all: finish the designated number of laps before the competition.  Those who turn in the fastest preliminary heats advance to longer feature races.  Two or more entries fly at the same time. This is a team event, with each team consisting of a pilot and one or two people serving as a pit crew. Upon the “go” signal, the pit crew starts the engine and releases the aircraft. One or more pit stops for fuel are required in each race.  Many of the aircraft are equipped with shutoffs, so the pilots can land whenever the team decides. Other elaborate equipment is designed to speed up the mandatory pit stops.  Watch for quick landings and fast restarts.  There are many classes of CL Racing, including Mouse Race, Goodyear (Scale), Rat Race, Slow Rat Race, and FAI Team Race, in which participants compete at a world-class level.

The competition wrapped up Thursday with the running of Clown Race and Sport Goodyear.

Clown Race rules specify a standard design, the PDQ Clown, a 50-plus-year-old design currently kitted by Brodak Manufacturing and PDK. Any engine can be used, up to a .19 displacement. Engine preference has become RC car conversions and FAI combat motors. Unlike other racing events, the winner is determined by who has flown the most number of laps in a specified time period.

There were two events being run Tuesday, Slow Rat and Goodyear. Slow Rat has been run with the maximum .25 engine size for a few years now. The powerful .36 engines previously used were getting hard to find and heavy, which made for a hard-pulling airplane.

Welcome to the 2019 CL Racing Nationals! I’m happy to be back to do the reporting after a few years off. Thanks to Melvin Schuette for his Nats reporting, as well as Brenda Schuette and their business, MBS Model Supply, that continues to be an invaluable source for specialty CL supplies.

This year’s racing schedule follows that of the last few Nationals. It’s reduced in time and has consolidated events to reflect the declining interest in CL Racing.
