This is VERY similar to ours, with very similar performance.

What speed are you running the belt at?

Right now 1-1 with a mini cim motor.

What about y'all?

we are gearing up 2 mini cims 1:4 (free speed output of ~24k rpm) but are using a fairly small diameter pulley.

What size pulley are you using?

Okay cool.

Were using two six inch kitbot wheels with guides on either side of the front wheel and conveyer belt material.

assuming loaded speed is approximately 5k rpm, your linear belt speed is approximately 88mph (great scott!) In a perfect world, your Frisbee will be leaving your shooter at 44mph.

We are somewhere in the neighborhood of a belt speed of 120mph. (Frisbee speed of 60 mph) as long as it all stays together.

Not to be "that guy" but I can't help but notice none of you have safety glasses on... ::safety::

Once we hit 80% power we didn't notice much difference.

Oh I guess you didn't notice, but we have those new safety contacts. :]

Haha yes! I'm glad we're not the only team that uses those. :)

Does your team have the force field ones to protect from debris? haha!

This one looks similar to ours, except I dont know much detail because I am a chassis guy and a driver :cool:

The monsters are creating a design to travel ~150 mph. I really hope the belt doesn't tear itself apart. I'm actually worried that it will rip itself apart :yikes: .
