after reading madcap magicians explanation i would go with the kr. because the kr has more rpm that is used more in 12th scale and also because run time in that class is an issue.

just my .02 cents

Well, It also depends on your driving style. If you are real smooth on the throttle and wheel then a Ti would be fine, you pull out of a turn and accelerate the Ti is going to punch hard. If you are a little abrupt on the wheel and yank the throttle, then the Kr is going to be a lot more forgiving.

Again, the Ti is meant for tight road courses, where low end torque and acceleration is critical. The Kr has a much smoother torque curve and a higher top end, making it great for oval or very open and fast road course set-ups.

I don't remember which brushes go on it, I've only brushed it once, and that was 3 weeks ago.

cheers guys

I would say mid-range power is really important in 12th, and the Kr has proven itself to have a lot of that. TC's need more low-end rip, which the Ti's give. I want a quad-magnet Ti

The KR motor would be perfect for 12th scale. It doesn't have the bottom end punch of the TI can. It wasn't up to par out of the corners today. Very smooth power band though...almost too smooth. I wouldn't reccomend running this motor with a GT7

It will be too smoooooooooooooooooooooooooooooth

Thats probably why mine is so smooth, I've got a GT7, but if you gear it just right it keeps up with 10x2 and even some 9x2 regular twin magnet cans.

have you also noticed the extreme amount of brake the motor has in it? I had to set up my car to where it's rolling off the line if I don't hold the brake at the start. How much timing are you running yours at?

You might need to go to a larger pinion to get less brakes if its braking too hard...A smaller pinion will give you better brakes.
Should be the same for RC cars just like slot cars

a bigger pinion will take away from what little punch the motor has.

I saw a Kr run yesterday. It had a smooth and endless powerband. It worked really well at our track.

The Kr is great for the XXX-S, the belt drive really takes advantage of the smoothness.

Now if the driver is too rough with it, then the Kr can look bad. You have to treat it like a lady, smooooooooooooooth.

Smoke ya later
