Default Will this work?

Im affraid my Novak 6.5 velosity might be to much for my SC10 this summer at the track. I have noticed that i can turn my throttle end position down on my transmitter to limit power at full throttle, thus giving me less rpm and slower speeds. So is it possible to do this for racing or should i buy a less powerfull motor. Some feed back would be real cool ! thanks for reading!

The kv rating of the HV 6.5 motor is less than most of the smaller 540-size brushless motors. If you run it on 2S it will probably be tamer than you think. The only issue is running the HV motor on only 2S won't get the RPMs up into that 30k range where you'd want to be. I don't think you have to worry about damaging your drivetrain, but it might not be the best setup you could run either. Give it a try and see how it performs.

I thought he said Velocity, not HV. These are 2 different beasts altogether.

The 6.5 is a bit much for most SC trucks. A SC10 is a true race bred truck, so it would have the best chance of doing well with a 6.5. But it will require some good tires, a good suspension setup and excellent driving skills.

The 6.5 may also run hot in a SC truck, but I cannot say for sure one way or the other. Some people have had good luck turning down the endpoints on their radios, but it is not recommended. A brushless ESC works by switching the phases on and off constantly. At lower speeds the ESC has to switch more often. At higher speeds its almost like the ESC is "resting", since the power is nearly flowing straight thru it! This is why most companies recommend gearing your vehicle to where you are able to use full throttle for at least a few seconds every lap. Like I said, many people have had good luck simply turning down endpoints, but in theory it can create more heat.

A 10.5 will be your best choice for the sc10, 6.5t is too much

yeah i was wandering if SimpleChamp was refering to the right motor being its rated @6400kv , this baby will hit close to 50,00o rpm .

I run a Tekin Redline 8.5 in mine indoors with the EPA turned down to help limit it a bit.

It seems just about right!...

I'll even end up bumping the EPA back up on some of the outdoor tracks this summer!
