I'm just setting my Cougar up now. I've read quite a bit about gearing on here but it's all a bit new to me to be hnest. At the moment I have a SP 10.5T brushless motor i'm going to use until i've got used to the car.

Can someone tell me what pinion I should use??? ( I have the standard kit gearing.)

What FDR does the motor manual recommend? What motor is it?

sorry whats FDR? It's a speed passion 10.5 V2

RW are doing 78 and 79 spur gears to fit the sv and sx2

if this is all new to you, then I would discourage you to run a SV.

I mean, the SV is an all out competition car. Not the best car if your starting out.

FDR stands for Final Drive Ratio, which is the final gearing of the car, which is calculated by, which in this case is:
spur (81 or 83?)
divided by
pinion (your choice)
multiply by the cars internal ratio (2.6)

with a 10.5, maybe an fdr of 8

so go for around 24 or 25 pinion to start off

One what grounds?

You've got to start somewhere and you're already gone for a sensible motor.

RW will do smaller - [email protected]
