Wind Power B/C

Thank you all so much for the help again! Do you know if we are allowed to bring a tachometer?

Hmm... I'd ask an FAQ if it hasn't closed yet. I don't believe there is explicitly anything against it, meaning it's allowed, but you should ask.

Are we allowed to put stuff on the CD such as tape or clay to aid in balancing it (they arent part of the blade)? I submitted a rules clarification but they never got back to me

If I were you, I'd mount such items on the base of the blade just in case. That way, there's no way it would be against the rules, unless some weird clarification has been posted

But what if the balance(tape or clay) is at a different point than the blade itself (so like in between two blades?)

I don't see a reason why you would have to add mass to a part of the device other than the blade. There's always a way around it.

Example: You have three blades. You want to add mass directly between blade 1 and blade 2. Instead, you add half of the mass to the base of blade 1 and blade 2.

You can add materials on the CD and hope that the ES allows it. I have done it. Just prepare to remove it and lose efficiency if it's not allowed.

Fair enough. so is modification only considered to be, basically sanding/cutting the CD in order to prevent cuts/sharp edges?

Not really- the only "modifications" you can do are putting tape and glue, sanding ONLY the area where the blades are attached LIGHTLY as far as I know. I believe the general rule is that it must aid in the attachment of the blades.

How did the Nationals wind power blade scores end up working out?
I am curious how this might effect the earlier discussion on whether the voltage score should be squared or not next year.
