22/23/24 with the 81, depending on track

make sure esc & motor are cool/warm not cooking

FDR = Final Drive Ratio, which is spur ÷ pinion x gearbox ratio (2.6 for a B4)

so 81 ÷ 22 x 2.6 = 9.57:1 FDR, you can work out the other two

I'd agree with Glenn, shouldn't be too far away with a 23 as a started for 10.
