Has any of you been to an invitational and know of top high and low voltage scores at the event? Please post the resistance used in the setup. Thanks!

Unfortunately, that information is kind of useless without knowing the motor as well. The motor itself has a huge effect on the voltage and those results would not be repeatable on any other motor. One of the most frustrating things about this event is that you can't really get an idea of how well your design performs ahead of time.

I concur; with different motors, it's almost impossible to get the same readings unless they are the same motor. However, that being said, as long as you improve on your team's setup, that will obviously translate to the competition setup, just with different readings.

I agree that the voltage output depends on the setup. Our team ends up getting lower voltages at the tournament even though the resistors used are higher, may be the motor used is of lower power than what we use. It would be helpful if someone can post the results from 2016 nationals.

Um okay how well do you know circuits...higher resistance means lower voltage because its harder for the turbine to spin the motor shaft

no...V=I*R. If R increase, assuming I remain the same, then V increase. V is the voltage drop. Or you can test it yourself. Just use higher resistance in you setup on the same blade and motor. See what happen.

I just helped ran an invitational event.

CD motor: https://www.amazon.com/gp/product/B00OT ... UTF8&psc=1
Load R: 10 Ohm

Top blade = 700mV+ on high, 500mV+ on low
Low blade = 80mv on high, 70mv on low

Was this B or C? (I'll go ahead and assume this was at Mira Loma yesterday)

B

Just post similar question to SO inc.
When you buy a bundle of CD/DVD, usually come in 25/50/100, you get the plastic filler. Can this plastic filler be used for blade? Has the same dimension as CD/DVD, but it's much lighter.
