Ok just used Brians calculator , with above set up it's showing 104mph but the motor will be spinning at 102000 rpm

they are only rated to 70000rpm that motor will disintegrate
Now if i use a motor around 9000kv with the same 65/40 gearing the calculator is showing 157mph

with the motor at 66000 rpm which is within the limits .
I don't understand how using a lower kv motor will yield more speed , maybe the calculator is not working right .
I put 1/1 in the differential section since the pan car is direct drive and 2.5" for the tires since that's what foams come in un cut ?
