The Task
Fly 3 precision flights to give 15,25,35 secs exactly. The times may be revised at the discretion of the CD dependent on prevailing weather conditions…..25,35,45s for the ideal windless day and 10,20,30s if its blowing a gale.
The Rules
1. Any flying model is permitted to include RTF, scale, profile, balsa , depron, and vintage fitted with some form of electric motor, battery and propeller. Both brushed and brushless systems are permitted as are EDF systems of not greater than 50mm diameter.
2. Hand, table or ROG launching is allowed.
3. Only one model can be used for this competition. If you break the model before 3 flights have been made, the flyer must withdraw. If the model is lost in a thermal, the flyer must withdraw.
4. The flight must terminate naturally without dethermaliser interference. This does not prevent the entrant from running a dethermaliser but he will withdraw from the competition if this operates when the model is in the air.
5. For safety reasons a recognised motor run timer or controller must be fitted to limit the motor run. These can be of charge limiting type for NiCad, analogue MOSFET or any of the digital timers such as FlyProf, Ztron, Leichty, KP or Infra Red. Adaptations of commercial clockwork timers are allowed.
6. A current draw limit of 3amps at 7.4v is considered to be the maximum allowable for safety within the confines of the Ferry Meadows field. This implies an AUW not greater than 200gm and a 32”span limit. Random checks will be undertaken for any model that appears to be exceeding these suggestions and the flyer may be asked to withdraw from the competition if it is judged that the flights are a safety problem for the public or fellow flyers.
Scoring
Flight time to be declared before launch.
Flight times to be rounded down.
1 point penalty for under or overflying.
The entry with the lowest penalty score wins.
Philosophy
This should give entrants a 2 hour workout with retrimming of flight and control systems to give the 3 required times and is intended to make modellers think of how to use and control today’s electric technology.
