The lower the number, say a 7.2, the more top end it will have but the more you will tax the motor. a 7.5 ratio will accelerate faster but will not have quite as much top end. However it will be easier on your battery, motor, and speedo.

2.5 is the tc3's rollout.

2.5 * 72 / 24 = 7.5

that sounds like it should be in the ballpark then, a 7.5 I mean.

you got it...
2.5(tc3's rollout) * 72(spur) / 24(pinion) = 7.5

in the manual for the tc3 is a gear chart as well.

so novak says to start with 7.30 (24/72)
but you guys think i should go with around a 7.5 becasue it will be easer on the motor etc.? so i take the rollout of 2.5 x ? / ? =7.5
any links with charts i can use to easly reference spur pinnion combo to final drive?
that 7.5 final drive is safe for the motor right?
what mph would that get me?

I cant comment on whether or not thats the right gearing, I was just showing you how to get the ratio.
in the back of the manual for the tc3 there is a gearing chart.
you said novak has 72/24 for a tc3 listed as 7.3??
72/24 with the 2.5 rollout of a tc3 comes to 7.5.

If you're not racing and just running around, there's no reason to take the gearing to the limits. To be honest you may not even feel much of a difference between a 7.3 and a 7.5, but you will get better run time and the ESC will run cooler.

yea your right i just want to get some speed out of it, i'm really getting bored with my tc3 with a 19t mod in it, but i think the novak will be faster even with the same gearing?
i have been looking everywhere for a mph calculator but i cant seem to find any?

What kind of 19T was it? It may be the same speed, but unlike that 19T, you won't be throwing brushes and springs at it and you won't need to cut the comm either. I just don't want you to be disappointed when it doesn't run like a 10T

its a team orion element 19t mod, i think i can get it to hit about 28mph but i would at least like to get 35mph out of the ss5800
thats the one of the reasons i want this system i want it to be able to go 35 and still in the back of my mind know that i can gear it to go only 28 or 45, i just need to learn how to figure what gears i need to do to get it to reach those speeds

another key factor in speed is going to be batteries..
what are you running now?
