I'd say grab yourself a 21, 22 and 23 and experiment!

I found that you can only just squeeze a 23 pinion in there with a 87 spur in the SC10? I've ordered a 84 spur, so I'll try that on the SC10 with a 22 or 23 pinion.
As for the B4, indeed I'll be turning the Mamba punch control up to 80% and lowest timing I think to get it driveable. I'm cool with that as I bought the 5700kv with a view to using it in various kit.
