NEED HELP ASAP
 
I have my first race of the year coming up. I’ll be running a dr10 kit with a traxxas vxl combo out of a rustler. I belive the lc is a 3500 and I have no idea where to start gearing. Any help with gearing would be great!!

You're looking for an FDR of around 5.0 I don't know the drive of the DR10 tranny or what spur you're running so I can't give a specific spur/pinion suggestion

so many options on spur gear count seen from 69- 87
along with pinions 18- 34
1st time out id run a smaller pinion with the largest spur i have till i get car adjusted so it will be a straight run down the 132 feet.20t to start .started my drag racing 20+ yeas ago with a bolinx drag car and a rc speed shop 24" both had spur on axel no trans no slipper and brushed sure we ran 20 cells both had foams and the ballooning was 2+ wheel diameter 4/5 turn custom wound motors
good luck in your 1st foray in rc drag

dr 10 comes with a 87 tooth spur, and a 18 tooth pinion. if your running that spur try a 21 and go down to a 14 if you half to. do this. YOU walk to the finish line run it to your self listen and gear it according to speed. if it tops out 3/4 the way to 130 feet then go up a tooth tell it goes past the finish line.. YOU want it to go to its highest rpm at 136 feet not to the next block.
