Peterborough Rules - Free Flight
General: For 2017: The classes will be, HLG/Catapult, E20, P20, 36 Hi-Start Glider and Cloud Tramp, plus the Bernie Nichols Trophy which will take place at the completion of other contest flights at 7pm on the dates of the three middle events.
One model per entry unless due to loss or serious damage the CD agrees to a second model being used.
Three flights to a max which will be set on the day, 10 second attempt: this applies to all the above classes.
Best four scores to count, fifth in the event of a tie. Scoring is 4,3,2,1,1, etc, or 3,2,1 if three entries, 2,1, for two entries, solo entry one point if three flights above 10 seconds are achieved.
Rubber Precision. For the Bernie Nichols Trophy (The Rubber Bowden.)
Models: Any rubber powered model that lies within the parameters of use at Ferry Meadows. Builder of the model rule applies. Traditional structure & covering. No Fo*m please, gentlemen. Traditional cabin type models are encouraged, and may be prescribed in future, to keep up the numbers, all types can be accepted.
Rounds: Two, with a target time of, normally, 35seconds. Ballot for launching order (first round). Less than 10 seconds... go to back of queue for another attempt. If duration exceeds 60 seconds, or if model lands under d/t inside that time, 25points lost. (because of the nature of the field and its surrounds, d/t can be used subject to above rule.) Launching order for second round is reverse order of first round score, ie best last.
Scoring: Flights timed to nearest full second, points lost per second deviation from target time. No disqualification for overflying. Smallest points loss wins. Flyoff in the event of a tie.
Three events are planned for 2017, points awarded 1 for last place, 2 for next best continuing upwards. All three events to count.
Up to 6 grams of rubber ( not 4grams )
Minimum weight 32 grammes less motor. This limit does not apply to models with cabins and two (or three) leg undercarriages. (This rule change was agreed at the F/F Conference that took place in December 2016, and is to encourage members to fit efficient d/t's without putting off newcomers by restricting performance.)
Span 36 inches tip to tip (NOT flat span)
Peterborough Free Flight Scale Propeller, Jet and Profile

This is an electric free flight class flown on a fixed power system to provide a level playing field for small field competition.
For 2018 the motors and timers will be provided to PMFC members on proof of a viable model. The recommended battery is a Turnigy Nanotech 2S 180mah (25-40C)
Open E20 - Provisional Rules
