Spur gear advice
 

Hi I have dex 210 with 85t spur gear but I want more speed do i add more teeth or less teeth as I'm new new r/c racing I would like some advice thanks a lot !!!:thumbsup:

Less on spur or more on pinion.

When you're saying speed if you mean top end then yes bigger pinion and or smaller spur, if you're after more acceleration the reduce the size of your pinion.

Hi,

I have added a link for you to a Dex210 gear ratio chart

Team Durango Gear Ratio Chart

Like already suggested if you are looking for top speed you would generally go for a larger pinion or if you are wanting more bottom end then you might go for a smaller pinion.

Always check when changing pinions that your motor is not getting to hot after your run :-)

I currently run a 8.5t motor with a 25 pinion on 87 spur

I run a 7.5t motor on a large astro track with a 24T pinion I have a 81T spur.

Thanks for the advice I have a 6.5t motor I have 83t spur & 20 pinion but just need a bit more speed!!
