You can give me or Aaron any stock motor you have and we will make it fast.
American (r/c) idols you both are...I should start pitting next to you guys...

And...if I could carry the speed you two have through the corners, I wouldn't be bothering much about my motors.

Or you could just come up to us and ask us for help. We don't bite. I am always willing to give out the setup I am running on my car. If I am at the track I will always help anyone dial their cars in, but you have to come up to me as I don't really watch people practice too much.

Hello there motor guys. I race stock rubber touring cars with Monster HP motors. What have you guys found to be the best spring combo for 767's and a small track? Thanks for all your help.

Thanks,

lunch,

For 1/12 scale, try green springs all around. Because of the lower voltage and amperage in 1/12 scale, purple and red springs are simply not needed. The reason for going to heavier springs is to stop the brush from being blown off the comm by the arcing that occurs. The only thing that heavier springs do for 1/12 scale is increase the drag on the comm. I have experimented with a blue spring on the negative but didn't have much success. Hope this answers your question.

I'm confused. Is it good to have a high motor amp draw or not? My motor only pulls about 7/7.5 amps and an experienced racing friend of mine says his motors draw 9/9.5 amps which he says is better. However, some of the posts in this thread suggest that a high amp draw is bad.

Is a monster or P2K2 better on a tight indoor track?

essnowyt the red/green combo is the best all around for the 767.

ralph c ...amp draw is good if their is nothing wrong with the motor ...but an oversprung motor or a bushing binding or shimmed to tight can cause high amp draw..

Ralph,

First, lets answer your second question. It's been a long time since I have run a P2K2. From what i've seen, they produce more torque than a monster. So it might be a better motor for touring car. But if your running a 1/12 scale, that much torque is not needed to move something so small and light. Go with the monster. Maybe. Here's something i've read in Big Jim's Motor Black book that has helped me when tuning motors or buying new motors. "Always go with the motor that produces the highest power number. You can always compensate for the lack of rpm or torque with the proper gear ratio." Here's why. Power (watts) = rpm x torque. It doesn't matter if the motor has a little less rpm as long as the amount of torque makes up for it. The reverse is true for torque. If the motor is down on torque, such as the new Epic ROAR stocks, the rpms should be high enough to bring the power number up when multiplied times the torque figure. Does this answer your question about the monster vs. P2K2?

As for the issue of how many amps the motor pulls. Generally speaking, the higher the amps, the more power it makes. This idea is fine for touring car, where the cars are heavier and making run time in a race doesn't really come into play. For 1/12 scale, run time definitely matters. I run 1/12 scale, so my good motors usually pull between 9-9.5 amps during break-in. If your motors are pulling 7-7.5 amps, they may need to be rebuilt or you may need a new one all together.

Hope I helped some.

I assume you guys are talking @ 5 volts for the above amp readings, please correct me if I am wrong

I got my amp rating at 3v I think on my friends turbo CFX during break in. I've just skimmed it and put in new brushes (4499's) so maybe the motor needs replacing. Still keeps up with the others well enough though. (need to improve driving before it will win me races anyway)

I've always run a monster up till now, but I was just looking on the Trinity site where it says the P2K2 is more torgue based so just wondered.

Thanks for the help.
