Gearing Advise with 13.5- TM2

[kyfran95220]

Hi all,

I'm a New tm2 owner, and i race with à 13.5t.
I presently use the durango 85 spur, but i don't know whether the 81 or 83 could not be better.
Which pinion with Which spur can you Advise me with m'y 13.5?

[Kusal]

I use a 10.5 with timing and boost and use a 28 on 80 RW spur gear (race on astroturf; Kampenhout)

[kartstuffer]

I use a 6.5 with 25/85 so compared to other cars I have run with 13.5 motors i would say about 34/85 or equilivent that would be with no timing or boost.

At the recent German 2wd Stock Nat's on Astroturf we used a FDR ~7.0
either with a 13.5 ThunderPower or LRP X-20 with blinky mode

Do you all use the stock spur (85)

I have order the 78 and 81 Spur from Durango ...

If I'm right ... FDR = 7 with a 13.5

so ... ...
1- 78/28 x 2.5 = 6.94
2- 81/29 x 2.5 = 6.98

Am I right ?
Is this the best way ?
