Blue Ray Electric Pylon Race
(This is a fun-fly event, not an AMA sanctioned pylon race event.)
Blue Ray Pylon Race Rules:
-
Pylons will be 150 feet apart.
-
The entrants will be divided into groups not to exceed six planes per heat.
-
Pilot's names will be called before each heat to give the pilot time to ready his aircraft.
-
All planes must circle upwind of the start line until the start signal is given.
-
Any plane that "false starts" by crossing the start line early will receive a one-lap penalty.
-
Any aircraft that cuts inside a pylon must fly outside the pylon before continuing the race.
-
Helpers calling turns for a pilot must stand next to the pilot. Turn Callers are not allowed at the pylons.
-
Contact with a pylon is acceptable as long as the aircraft flies around the outside of the pylon.
-
Aircraft may be repaired between heats. Backup aircraft substitutions between heats are allowed.
-
Aircraft battery charging or replacement between heats is not allowed. If a backup aircraft is use, the original battery must be installed in the replacement aircraft.
-
Heat Races: Heats shall be 10 full laps with points awarded based upon finish order. If in the opinion of the CD, two planes are too close to call, they will be awarded the same points.
-
Determining the race winner: The pilot with the highest number of points shall be the winner.
-
Heat race points:
-
1st Place = 10 points
-
2nd Place = 8 points
-
3rd Place = 6 points
-
All aircraft completing 10 laps = 4 points
If a points tie exists after all heats have been run, the tie breaker will be a final ten lap race with the first to finish declared the contest winner.
