All hail props

We're running the prop directly off the CIM because with that size blade we kept tripping breakers trying to gear it up. The pitch is 10, with a special cut on the blades to give it more forward push (I think the blade says 3DA, which we figured out was a 10 pitch). We got about 5 lbs of thrust exactly on our little thrust rig. We do plan on experimenting with an 8 pitch before the regional though.

Yeah, I have a feeling those of us with working props will have a fun time at the regionals.
