XRAY - Model racing cars

Hello,

I want to buy pinion for may Xray T3 EU.
I'm using Tekin RS and Vector X12 17.5T, Spur 84/48 stock
Race on Carpet. Tyre: Sorex 28R

Could you recommend how much teeth must be?

Thank you.

it depands on track and etc
give me photo of a track

the best option is to buy set of xray's pinions

At this momment I'dont have photo of the track.
But there are a lot of corners. And only one straight. (~20-25meters)

Can you specify what you think could fit around? (As example from 22 to 25)

you need fdr from 6-8

you need pinions from 20 to 26(including those 20 and 26)

but gearing depands on boost and etc

look around,and ask for help another drivers,what they recomend for kinda track

I run a X12 13.5 and 10.5 with a Tekin RS Pro indoors and usually gear at 8.4 or 8 FDR (19 or 20 Tooth)

Find it gives a decent top speed and enough punch out of corners with suitable timing settings.

If cost is an issue I would start with 23 (6.94) then add a 24 then a 22. If you can get several then leave Turbo at zero, set Boost to 40 and throttle profile 2 or 3 and try each pinion and see which gearing is suiting you best. Then add some timing keeping your eye on temperature. I suspect with your track you want to concentrate more on boost for midfield punch rather than turbo (maybe limit to 10). All a bit of guesswork on may part though without knowing your track

Thank you. I will try on weekend.
