I think the problem with your reasoning is that "easy tasks do not make easy competitions". In fact they do just the opposite -- they result in difficult competitions where the most talented flyers fight it out not over thermalling abilities, but the ability to hit the target time exactly. (And the landings become paramount) I have been trying to analyze all of the results from this year's F5J Intertour and appears that in these events, where the pilot essentially selects the launch height needed to achieve the task time, that competitive pilots are very frequently choosing heights around 100 meters. When I get more time this winter I will provide a detailed breakdown. It is important that our rules provide interesting tasks for a wide range of skills and interests. But relatively easier tasks do not necessarily mean more interesting. Quote:
As for the runway landing, some of us have actually flown ALES and the runway. The runway is surely no miracle solution for anything, but it is an entertaining and interesting task -- and fair. And having worked at it with my ALES planes I would observe that it presents pretty much the same problem to ALES planes as it does to TD planes. Whereas I find it much easier to score with an ALES plane on an ALES tape, my scoring with the ALES plane is pretty much the same as my TD plane on the runway. In the limit, a runway with a 50 point max is a good compromise toward providing a task that does not become THE contest while providing a task which will sort out close thermal skills -- IF THE THERMAL TASK IS REALLY A TEST OF THERMAL SKILLS. Happy Landings, Don |

Tasks
Interesting Don that 100M is the number for the F5J guys. When we flew 100M at Dayton, I thought it would look really low, and it did not at all, and it is all realitive with everyone else at the same start. I do think that about any launch height a CD wants to call can be a good ALES event dependent on conditions, if it is really crummy, then 200, really good, then 100. I think a CD could change the height during the contest to kind of tighten the screws if he might be a real buzzard. Landings As Don, I think it is tougher as well to hit a 95+ landing on a one inch TD tape than a 45+ landing on the ALES tape, even with a skeg. 10 inches is a pretty small piece of property vs. 4 meters. On an inch increment tape, I am very happy to be making 80+ scores on them. The only reason that I thought that the runway landing was a great comprimise was that slides became less of a dice roll since the scoring slice of the pie runs along the approximate same axis as the flight path of the sailplane. It is just an alternative to using a circle. Marc |

. One of the things I have discovered is that when I fly to 200 meters I waste a lot of that altitude -- some out of complacency and some because I cannot see what the plane is doing as well at 200 meters as I can at 100 meters.I'll leave it to those who are at higher pay grades to figure out what makes the best event. The one thing I know with absolute certainty is that I feel like I have accomplished more when I make 10 minutes from 100 meters than I do from 200 meters. Given that, however, I still know that nine times out of ten, Larry will make more out of 100 meters than I will. That's why they award trophies and not certificates of participation. But for me, the participation is still enough of a reward. Happy Landings, Don |

Timing
Quote:
It is very obvious on a winch launch when the glider drops the chute, I defy anybody to tell me when an electric motor stops turning at 200m. That is around 630 ft !!.All the timers with probably widely different visual accuity. Not very likely. Nobody can mistake when the thing leaves the launchers hand 5 or 6 ft from your nose ?? Ken. |

Hi Ken,
Here is how we do it. We have a 30 second motor run window at the end of that 30 second window the recording says all motors off and timing starts now. Then the recording annouces every minute of flight time and counts down the last 10 seconds. That being said your timer keeps the offical clock. Agreed there wouldn't be an accrate way just by obseving the aircraft. Mike |

Most times no we don't use a 10 second launch window. However you could if you wanted. As the recording announces the opening of the 30 second motor run time concurrently that is the opening of the 10 second launch window, 10 seconds later all planes must be launched. At the end of 30 seconds all motors off and timing starts now.

I can't see how that would work. Unless you launch at the buzzer, you would have less than a 30 second motor run, perhaps as little as 20 seconds. And since it is so difficult to tell if the motors are off at 200 m, you would have to rely on the pilots shutting-off rather than cut-off timer.
That method forces everyone to launch at the buzzer, and increases the mid-air danger at launch. Kevin |

Kevin, it works. I know , I have CDed about 10 of these events using this system.
The round begins with a 30 second launch window. The aircraft may be launched at any time during this 30 second window, BUT, the motor must be off by the end of the 30 second window. If the motor is started immediatly and the model launched then the motor is shut off by the CAM unit after 30 seconds, or at the pre-set altitude. Some of us prefer to wait a little until the slower models are out of the way, and then launch, knowing that our models take only 14 seconds (in my case) to reach cut-off altitude. Whichever method is used, the transmitter control is placed in the OFF position at or before the end of the 30 second launch window, at which time ALL individual timing devices are started. I hope that clears it up for you. Iain |
