Hi
i had the same question about 210 gearing this is what i found
According to Novak the recomended gearing for a 2wd buggy is 9.5

if you then look at this

notice the spur only goes to 87 which is std, if you get 87 or smaller spur it will move the motor nearer the rear axle
another problem running a bigger spur is that you may not have room to get a big enough pinion on

I think i'm running a 24/83 at the moment with an 8.5.

I couldn't get a big enough pinion on with the stock 87 spur (25 was the biggest IIRC). So with a 91, you will probably only be able to get a 21/22 on there.
Might be time for some smaller spurs.......

I ran 24/87 with an lrp 7.5 at Silverstone and pretty much everywhere else.

I think this also depends a bit on what motor you are using here

I have a SpeedPassion v3 7.5t running a 24t/87t. This is for a small/medium indoor track at Maritime so would likely go to a 26t for outdoors

So that was a typo on my ipad i meant 81t

i have always run 23 on my 81 spur on an 8.5 LRP motor

ahhh thats makes more sense lol.....22 then :thumbsup:

Depends on all variables, I used to run29/87 with a 10.5 blinky mode, now run a 23/87 in boosted mode with the 10.5.
