Gear ratio difference between RC4WD R2 and 2speed?

[greasypete]

Hi,

my scale tuber has a R2 tranny with a 55turns motor. It crawls perfect, real slow (with axial axles and 2,2" tires).

I am thinking of adding some speed with a second gear.


My question: Is the R2 two speed gear ratio in first gear the same like the singlespeed R2, plus a slightly faster 2nd gear ? I am not sure about that ...

They say on their website:
Two speed: 6.7:1 (with 8 tooth pinion gear) or 11.4:1 (with 8 tooth pinion gear)

One speed:10:1 to 30:1 Gear Ratio (8T to 20T 32 pitch pinion gears)

It looks like the gears are completly different on the two speed version, or am I wrong?

Thanks for any help with that, bevore I buy something !

Could you run different pinions to get the same first gear ratio that you have now on the 2 speed?

I got answer from RC4WD (thanks!):

Its different, the gear ration in 1st is much faster. A smaler pinion wount help, because I already have a very small one.
