Spur gear on mi3.5 which

[the pitman]

We need to replace the spur gear on Corys car.

In the manual it lists six differnt one's from the 85t up to 89t 48dp (which he has now) and the 114t 64dp up to the 118t 64dp cnc gear spur.

They all cost the same, so which one would help speed us up, which ever one we go for we will also get the schunacher pinion to go with it(as I think running a tamiya pinion has caused the damage to the original spur)

thanks.

Simon.
