Default SC10 Gearing - 17.5T Brushless

Hey guys,

I am all turned around regarding chosing gear ratios and need a sanity check. I am currently running the SC10 RTR brushed motor and speed control with the stock gearing (87 tooth spur). I bash a little and have run on some local tracks (most are clay and one is a pretty loose when it gets dry).

I just picked up a Novak Havoc 2S Club Brushless Combo - 17.5T (Part #: S3035) and want to make sure I get the gear ratio right for this brushless system so I don't overheat the motor.

I started at this website: http://www.comeseethis.com/gearing

I filled in the blanks (SC10, Novak, 17.5T) and a 75T spur gear and the suggested pinion ws 26T to get a final drive ratio of 7.5:1.

I want to pick up a couple of extra pinions to help tune the truck for different conditions (especially if the motor is running hot) and figure going +/- 1 tooth is the way to go (25,26,27).

A few questions:

1. Any reason not go with the 75T spur?
2. Does any one have any experience with the 75/26 combination and the Novak BL system?
3. Should I go down teeth from 26T (24,25,26) instead?

Thanks in advance,

Craig
