Hello, I was taking pictures at the LCC electrathon race on Saturday and I've posted them on my website.
Also, if you are an instructor of an electrathon program send me a message and I will give you a coupon code that would allow you to purchase prints or downloads of the photos at cost.
The wheel covers are mostly out of 1/8" ABS black plastic and white styrene cut to shape and attached with zip ties. I think this adds about 1/4 mile at least as the wheels don't move as much air.
