Ok the Rear shocks have the number (2) shock collars on the bottom and the Front one of them has a (1) and the other (0) .

Default Spur - pinion gears ratio

Hi guys,

Can somebody help me understanding the Dex210 v2 gear chart? It is on P.45 of the manual.

I'm still learning about rc cars and my Dex210 and I've been told that I should change my pinion and spur gears to a 69t pinion and a32t spur (I think, I didn't write down what this guy at my rc track recommended), The set comes with a 81t pinion gear and a 29 spur gear.

I would change them asap but I have no idea about what the meaning of all the numbers I see in the gear chat is. What is the meaning of the 2.6 internal ratio? 81t and 29t apparently give me 7.26, but what does 7.26 mean? How do you calculate which pinion correspond to which spur? I saw this guy using his calculator to tell me I should go 69t with 32t? But I didn't get why.

I hope somebody can help me.

Thanks.

Does using those hexes along with AE wheels retain the factory width of the car?

That's a good question . If more than one guy does it i guess it remains the same wheelbase guess its fine.

As I recall when I did the measurements the net change is -.5mm per side.

So it sounds like with the 12mm your narrowing the track witch that might be a bad or good thing .

If you want the same track width or even a little wider just use some track width spacers. Avid makes some really sweet cf ones in .5mm and 1mm widths. I played around with some different widths and actually came to like the -.5mm per side width. I do race on a super tight indoor track though, so you may like something different.

Thanks.
An internal ratio of 2.6 means the layshaft gear turns 2.6 times to turn the diff once.
7.26 refers to the final drive ratio, how many times the motor spins to get the wheels to spin once.
To work out your FDR use this formula. (Spur Pinion) x Internal Drive Ratio = Final Drive Ratio.
I'm guessing you are running 17.5 buggy from what gearing you were recommended.
