Motor ???
1s or 2s ???

[jonathan may]

13.5 1cell

A 28 pinion and 70 spur will give you a ratio of 2.50, I would start there.

[mark christopher]

65 to 70mm/rev

[jasond43]

as mark said 65mm is good to start as it depends on how big your tyres are too so its best to work to the rollout

I actually run at 62mm/rev and was thinking of going down a little. I think a good starting point is just that. It all comes down to driving style as well. I know I lost out last week, because I just couldn't get close enough to the guy in front, coming out of the corner, on power.

i use a 30t pinion on 70t spur approx 67mmpr (track size 30m x 15.5m)

[rondoolaa]

Is 31 pinion 68 spur ok

I'm on 1s
13.5 thunder power
49.6 tyres
With a 71.04 rollout,
Gear ratio 2.19

Track is 1 long straight and the rest is winding.
This track but will be slightly different.

Hi there, ive just got into the world of 12th superstox/mardave etc and im just wondering what gearing to start with. Im running the 70 tooth spurgear, and at the last meeting in used a 30tooth pinion, but it felt a little slow but the motor was only 'lukewarm' when it came off the track after each heat. Im using the basic standard 'Silvercan' brushed motor and a 1s lipo. Im racing at Dudley indoors on carpet, and id say its a relatively small circuit due to being in a school hall. The tyres ive currantly got are at the limit and about 43mm dia, but i have new tyres to true up once i know whats the best size to go to to start with?

Any help will be appreciated.

A couple of nicad packs would be better suited to silver can brushed sue to the higher voltage, it will feel flat with your combo I'm afraid.

If you run on a tight track with lots of corners go for a 28t pinion with a 70 spur. With a long fast track, a 30t is more suited.
