We don't know for sure, but today we got our 3rd or 4th iteration of the prototype working, with a curved shooter going thru about 90 degrees, with a 6" wedgetop tread wheel driven by a CIM and geared up in speed about 30%. It shot around 30 feet to about 6ft height (shooter on the ground), shooter angled up maybe 15 degrees. I think we'll probably go with this, the neat thing is with the way the thing is set up with sprockets and chain, we can change the ratio to get about any speed we want from 2000 to 8000 rpm or so at the wheel.
