Re: Elastic Launched Glider C

The bonus you are describing, while possible, seems overly complex. I hate to make the event supervisors think too much. The current method of adding flight times is easy to understand, rewards the teams who practice, and can be scored with a calculator. My proposal to reduce the effects of luck an...

Re: Elastic Launched Glider C

Proposed bonus for gliders If this bonus is accepted then I will try and talk someone into publishing a paper that will describe all the math needed to predict times taking into account the differences in air density. It appears that it is something that with the right guidance a team can do. As a ...

Re: Elastic Launched Glider C

Such a prediction bonus would have the effect of penalizing teams with superior gliders and rewarding teams with average gliders, i.e. gliders not capable of flights with a 1 foot per second descent rate or better. There is a lot i don't know about gliders, that's why i ask people who do, about a m...

Re: Elastic Launched Glider C

The bonus would be an elective flight taken within the given flight time and would replace one official flight. So a team can take 6 official flights and the top 4 are scored or 5 official flights and a bonus where the top 4 flights are scored plus bonus. The exact time bonus is a single flight atte...

Re: Elastic Launched Glider C

Proposed bonus for gliders Six official flights four of them will be scored. Within those six official flights an optional flight can be utilized to score the bonus. (4 flights + bonus) the bonus will consist of an exact time flight. The exact time will not be known before the competition and releas...

Re: Elastic Launched Glider C

Leave the ELG rules alone with the possible exception of increasing the max wingspan to 35 cm or 40 cm to encourage further experimentation. I am not sure that slightly larger catapult gliders would fly longer, but I suspect that would be true. There would be zero incentive for a team to change win...

Re: Elastic Launched Glider C

First off a coach needs to know nothing about an event. I never heard of catapult gliders until it was a trial event last year and our team did not participate Next, a coaches job is to find the resources for his kids. I drove 3 kids 200+ miles once or twice a month to meet with the Ama guys. Finall...

Re: Helicopters B

The reason I asked for the basketball courts on either end of the volleyball gym is that they had acoustic tile ceilings and were more than high enough The reason I object to the volleyball gym is the trusses are a monster waiting to catch helicopters Now, for gliders it is a different story. Demons...

Re: Elastic Launched Glider C

OK, had a chance to digest everyone's posts since last night. Seems to be two, related, suggestions on how to increase the importance of data collection by integrating a prediction component, similar to other tech events. But, I'm having trouble following the details of the suggestions. Can I reque...

Re: Elastic Launched Glider C

why was there no minimum weight this year? Past flying events all had minimum mass required, right? Doesn't that help, in that teams won't have to worry about spending money on buying the best balsa? A sheet of 4.5# balsa that makes two 30cm wing span gliders is around $3.50 and easy to come by. A ...
