We had our kitbot running today and did a speed test.
Our configuration was using 6" wheels.
also used the 21 tooth for the counter shaft
and the 28 tooth for the wheels
we measured it's speed to be 5'/sec

If you figure those cims are running at 5300 free speed
reduced 12.75:1 (gear) and 1.333:1 (sprocket)
we should have been moving 8.15'/sec

There wasn't much if any efficiency loss in the way we had it assembled, and the speed test was fairly accurate +/- .5 sec

I'm thinking those cims are turning more like 3300 rpm

Has anyone else experienced this?

Originally I thought everyone using the kit chassis/trans. and 8" wheels would be up in the range of 10.5'/sec but after seeing this, it's looking like they'll be traveling more like 6.5'/sec

One thing I didn't check (as I'm thinking of it now) is that we may have not been applying full power to the speed controllers, as we just grabbed an old RC and ran it. But I doubt the code wouldn't be full power.

edit: reduction ratio (oops)
