Hi Can some one tell me please what the gear ratio on the standard raptor 30 is?
I have a V2 box electric raptor and i need the gear ratio to program my new speed controller to be able to set the govner mode in the ESC.
I know that the ratio for the box is 2:1 but i have no idea what the standard ratio is any help is most appericated.

count the teeth on the main gear, count the teach on the pinion. Divide, the result is your gear ratio.
Ex: 85 tooth main 10 tooth pinion (Raptor 50)
Ratio = (85/10):1 = 8.5:1
My research shows the 30v2 has a Gear Ratio: 1:9.56, but yours is an electric conversion? If so, then the gear ratio is probably different, so, do a count of the teeth as above to make sure. (To not lose your place on the main gear, mark 1 tooth with a marker. Turn it with a small screwdriver against it lightly and count the clicks, makes it easier.)

Hi Ghtracey many thanks for the info the way the gearing is done on the raptor is that the output of the motor is put thru a 2:1 reduction gear and then fed to a raptor 30 standard motor and pinion setup. i will count the teeth anyways to be sure. again many thanks for your help

The standard Raptor 30 gear set is a 9 tooth pinion and an 86 tooth spur gear (9.56:1).
Take care,
