Re: Scores B/C

4th Place National Bridge (post Nationals)- Boca Raton Community HS. The design had a test efficiency of almost 3000, but we scored 2633 at Nationals. What's your tension? Is that balsa or bass? It looks interesting... It is bass and we laser cut it to a specific width (it is dark because of the la...

It weighed 5.15 and held 12.65kg for a score of 2456, though our scores were usually around 2600-2700 with the design

Re: Scrambler C

does anyone know the range of scores for top 5 at nationals? Mr. Pratt, the event supervisor, will probably post the distances/times/scores for the top 10 scramblers sometime over the next couple days to this thread (at least that's what he did last year). I know we took 4th with something like a 2...

Re: Flights at Nationals

I might be able to get a video of our flight (4:12) and I'll see if I can get a link to it soon.

Re: Scrambler C

That's a little different than my spring design. We had a very simple one (had a big pulley and a small pulley and used torque to pull back a relatively stiff spring) but we never had time to build and test it. I'm currently using a simple falling mass and string launcher that shoots the car out ki...

Re: Scrambler C

How are you guys able to achieve such good times? Are you using a spring launcher? Our system used surgical tubing for the spring portion and a pulley on the mass side of the spring. The pulley halved the distance the spring needed to stretch while still allowing the mass to fall almost the full 1 ...

Re: Raw Tournament Times

someusername, Sorry, I was typing too fast earlier today. Backoff winds when 1/2 motor testing should be approximately halved just like maximum turns are halved. I made a mistake in the post above indicating backoff turns for a full wind. For a first 1/2 motor test flight wound to 750 - 780 turns, ...

Re: Raw Tournament Times

someusername wrote: My first question is how do you increase your maximum height exactly? The gym at my school is roughly 30' tall, but even at full torque we could maybe get a maximum altitude of 40' (more or less). What variables could we change to increase the height without hurting our time? Je...
