Pinion size ?

[RobPaynter]

Hi guys and girls.

Just finishing my dex410v3 build. Just woundering what size pinion to use. I am running a LRP X12 5.5t octa wind. Going to be running it indoors to start with then summer outdoors.

What size are people running?

Thank you for reading.

For a start don't think you'll need a 5.5 for indoors but i'd use a 20/21

I would try a 19, depending on esc settings, driving style, track layout ect I dont think you will do any harm to anything on a 19, I'm sure you could maybe go up a few cogs once you get the feel of things.
