12th Pan car gearing Help!!

[DNC]

Hi
Needs some help please!
Running L4 1/12th pan car. Just fitted new 13.5 brushless but not sure about gearing it! AMC suggested fitting a 58T spur? (Done that). But not sure about pinion gear! Racing a medium size indoor carpet track. tyres measure 47mm

Any ideas on a starting point would be good - thanks

are you using 4 cell or the 1s LiPo saddle packs?

4 cells

start on a 25 pinion and try one size up each run till the motor doesn't appear to pull out of the corners

if you've downloaded the spreadsheet enter the spur gear size and then look down the column for your tyre size.

25 comes out at 63.64mmpr

which esc are you using?
