GEARING QUESTION: Pinion Range for TC5R

[lucas-b4-b44]

The Kit Spur is 87Tooth 48Dp.

What would be the range I should be looking between for a 13.5T?

The LRP 13.5T Eraser Brushless Motor guide says I should have a ratio of 6.0:1 for 1/10th TC and that means a 29 48Dp Pinion.

but I can't find anything official from TC5R manual online etc...... or on the AE website.

but on all the forums people talk about 4.0:1 ratio's????? Thats a 43T Pinion?

Where do I start?
