This application can be used to time ad-hoc R/C races. It times 1 race with settable time limits, and minimum lap times, using manual lap counting (not transponders). It follows standard R/C racing format where the race is run for a given time. After time expires, racers continue until the next time they cross the finish line. Scoring is by number of laps and the elapsed time of the last lap. The higher number of laps, or lowest time if tied, is the winner.
