FAI F5J 2013 New Years day and Janurary and Feburary
Since at some point in time it will necessary to create a team select for WC in F5J, I would like to have at least a RC-Group competition, to demonstrate what is going on in the world and the possible equipment that would be successful on a WC level.
At this point in time I am hosting a New Years day, and Janurary competition for F5J.
The rules are below and only represent a generalize competition, however realize in almost every round at a World level someone always makes time and a landing of 50 points. Since current rules allow for a 30s motor run, in the 10minute flight window it will be possible to do exactly 10:00 minutes of flight time. So starting height becomes the discrimnator for the final score as you have 1/2pt subtracted from you total score for each meter of vertical height you launch to, and 3pts per meter if your starting height is 200M or more.
To normalize your score I will have to do a little math.
You will have three values, starting height in meters ( -.5 points per meter), flight ime 1 point per second, and landing points up to 100pts.
Example:
starting height 150M so -0.5 X 150 = -75.0 pts
flight time 9:58s or 9min x 60pts + 58s x 1pt = 598.0 pts
landing points say 45pts
total 568 pts (raw score)
If this where the highest point total flying againt five other competitors then you would receive 1000pts for the round. If the second highest raw score was 550pt then this pilot would receive 550/568 X 1000pt = 968.83pts
As you can see only 18pts(raw score) or maybe just a height difference of 36M with each having the same flight and landing seperated the two scores. So in the current rules starting height is a major player in determining final scores.
Since I do not see more than 6 to 12 scores on New Years or Janurary I will just normalize for the group once you have entered your raw scores.
You may submit only one score for New Years and a new single score of Janurary. At the end of the month, all raw scores will be normalized.
The final requirement is you must submit a graph from your flight recording showing starting height and landing time, I will just trust everyone on landing points. Pictures and equipment list are always welcome.
I realize this event will only appeal to a very small group of pilots as does F5B and F5D, but at least we will have some pilots looking at a new and very diffcult event on the World level of flying.
Please remember anyone with a electric sailplane height recorder and landing tape can fly this event.
FAI F5J generalized
TASK: Fly one 10min flight.
1. Any airframe, battery, ESC, prop, motor maybe used. To FAI limits.
2. 10:00 minute window, with flight points starting on launch. Over flying window 0 landing points.
3. A device to record flight starting height, after a 30s or less motor run, at the beginning of the window. To establish starting height fly level for 10s after motor run.
4. .5pts subtracted for each meter of starting height, 3pts subtracted for each meter above 200M, from possible 10minute flight time ((600pts or number of flight seconds) - (starting height(.5 or/and 3))).
5. 50pt. landing tape, - 5pts per meter from 50pt end of tape. Landing points will just be added on since you are not flying in a group to normalize scores.
Hope you can joins us for the fun.
