Ohm's Law

I see that a lot of people use 1515 1.5d or 1y on 4S and use 1y as a moderate racing motor. But I want to use 6S, so I ordered the 1515 3D to get about the same rpms the the 1y 4S combo, so will I have about the same speed but about double as much runtime?

the 3d is a bit slow on 6s the motor has a KV rating of 1360 which will give you a RPM total of about 30,000...I like to keep the total @ 35,000-40, 000, I have the 2.5d on 6s and I am happy with the results

Most people use the 1515 1y 2200 kv on 4S and that's 30,000 rpm. The 1515 3D 1360 kv on 6S in 30,000 rpm. So I'm right on. I'm racing it on a medium-sized dry track where too much motor isn't good.

I didnt know you are racing on a smaller track, I assumme gearing it for 35mph would be right....I am a basher so my mind was there....
