4.2 GENERAL RULES
Scoring. All Open events are flown to 5 rounds of 3-min maxes with no model restrictions. The winner of the event is the entrant scoring the highest aggregate flight time. The number of rounds and maxes may be varied by the CD to reflect conditions and entries during the events. In the event of a draw at the end of the declared number of rounds, a fly off with incremental maxes will be flown until a winner is declared.
Engine running. Open power models are restricted to a 7-second engine run.
Open Gliders. Open gliders are limited to a 50m towline. Top

Free Flight Scramble
Aim. This event is open to any model defined as "Free Flight" by BMFA rules. It is a fun event in which the aim is to log as much flying time as possible in a 30 minute period, but the model must be recovered to the starting line for each re-launch. The following rules apply:
Timing. The contest will take place within a specified 30-minute period.
Assistants. Each competitor is allowed only one assistant.
Over 50’s helpers. Only the competitor is allowed to retrieve his model after each flight and retrieval must be on foot. To safeguard to health of 50-year-old members, an assistant is allowed to retrieve models from a long distance.
Scoring and timekeeping. The score shall be the total duration of all flights made within the 30-minute period but only flights in excess of 20 secs are to count. The maximum score for each flight is 2 minutes. All time-keeping will cease immediately upon the ending of the 30-minute period, notwithstanding that a model may still be airborne.
Flight preparation. Prior to the start models may be fuelled, charged or otherwise prepared for flight. Subsequent preparation for flight may only take place at the start line. For electric models spare batteries may be charging at the start line during model flight and recovery.
Reasonable effort. A competitor must have made a ‘reasonable’ effort to achieve a qualifying time. Not make one flight then retire. This is at the Contest Director’s discretion. Top
