General

For 2021 the classes will be HLG/Catapult Glider, E20 (to PMFC Open rules), P20 (see minimum weight limit) 36" Hi-Start Glider, Cloud Tramp and Kit/Plan Scale Precision.

Contests normally begin at 3.30pm and end at 7pm, except for the final one in September, which begins and ends an hour earlier.

Two models per entry are permitted. Three flights to a max that will be set on the day, 10 second attempt: this applies to all duration classes.

Usually there will be five rounds, on predetermined dates. For 2021, however, there will be four rounds, best three scores to count.

Scoring is 4,3,2,1,1,1 etc, or 3,2,1 if only three enter, or 2,1 if two. If only one flies in any class, the competitor must make a bona fide effort. This is defined as two flights over half the max, or three flights over the attempt time.

Timing by club members or recognised assistants: competitors are asked to be available to time others when called upon.


Rubber precision for the Bernie Nichols Trophy

Models: Any rubber powered model with cabin (or cockpit) using traditional structure and covering, such as would comply with SAM 35 "Rubber Bowden" rules. Builder of the model rule applies, except for the tribute flying of models constructed by past members of PMFC.

Rounds: Five, except when weather conditions dictate fewer: at least three must be flown. There will be a ballot for launching order. Target time will be either 30 or 35 seconds, to be defined prior to the start. Flight of less that 10 seconds? Option to refly at end of round. Flights of over 60 seconds scored as 60 seconds, as will be any flight terminated by a d/t.

Scoring: Flights timed to nearest completed second, one point lost per second deviation from target time. All rounds count. Smallest aggregate points loss wins. Flyoff in event of a tie.

BNT Trophy to be held annually.


P20

Up to 6 grams of rubber ( not 4grams )
Motor may be external
Max prop dia 8 inch

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.)


E20

Please refer to Peterborough E20/Open E20 rules.


Hi-Start Glider

Span 36 inches tip to tip (NOT flat span)
Hi Start 7.5m of 1/8” rubber Plus 22.5m of line
Same Hi start used by all and not reeled in between flights.
Models – ANY glider (vintage, modern, scale, kit, O.D.or existing design scaled up or down)


Peterborough Free Flight Scale – Propeller, Jet and Profile

Static scoring (marks out of 10 for each)
1) Accuracy to provided plan (no three view required) 
2) Finish 
3) Detail 
4) Workmanship

Maximum static score 40 points

Flight Scoring
Minimum flight time to qualify 15 secs 

Marks out of 10 for each (best of three flights) 
1) Launch/take off 
2) Flight 
3) Landing

Maximum flight score 30 points

Add static and the best flight score (of the three) to arrive at competitor’s total for the event.


PMFC Kitscale Planscale Precision

New for 2021:

Any scale model built from kit or plans. Please keep closely to the spirit of the original design. No static nor flight judging. A target time will be announced on the day (normally 25 or 30 seconds.)

Three flights, attempt may be called if any flight is under 10 seconds.

Lowest aggregate score wins.
