Rc speed calculator: What going wrong

[danny the elfman]

Hey guys. Been trying an rc speed calculator for my b44 but it doesnt seem to be giving out the correct reading. I know my car is doing more than 17mph. What i have typed in wrong? Thanks

Think the transmission ratio you entered includes the diff - it's calculated an fdr of 23?, would expect more like 8-9
Try changing the diff reading to 1.

According to that, my tlr22 should hit 52 mph
