Here are the relevant rules from the FAI (see the freeflight rules under Section 4 of the FAI Sporting Code from the url given by Brett). So, the timing stops at the moment anything, motor included (?), falls from the plane. As an aside, the AMA rules for US ony classes are sightly different. Bill Gowen has petitioned the AMA to change the US rules tomatch thse of the FAI below. This petition seems to have some resistance.
3.4.9. Timing of Flights
The flights must be timed by two timekeepers with electronic stopwatches with digital readout recording at least 1/100 of a second.
From Section 4b. para B.13., only B.13.1., B.13.2., and B.13.6. apply to class F1D.
The timing of each flight shall commence when the model is released.
Timing will terminate when:
a) the model touches the floor of the building.
b) jettisoning occurs.
c) the model comes into contact with any part of the building or its contents other than the floor and translational movement ceases.
Note: In this case, the timekeepers shall continue to time for ten seconds after translational movement has ceased. Should the model remain in contact with the building or its contents after 10 seconds, timing will cease and the 10 seconds will be subtracted from the flight time. Should the model release itself from contact with the building in less than 10 seconds, timing will continue normally.
