Thanks Mike!

The this is the same motor with the top pull at zero timing and the bottom pull at full timing. As you can see there is not a huge difference but it is there. As you apply more voltage or turbo/boost the difference will get larger. This was tested with a spec speedo profile (LRP 007 Comp speedo).

I've been eying this motor for awhile now and I would like to get some personal opinions on it. What I want is a 17.5 non-boosted and it would go into my sedan. The track I would be racing it on is a pretty large carpet track with about roughly a 100 ft. straightaway. So my question is, is this motor going to have plenty of power for this large track or is it more of a short track motor?

My track is roughly the same size, I run a non boosted 17.5 Duo 3 with max timing geared at 4.06 and am happy with it, my temps stay between 140-150.

I think you will be MORE than happy with a D3 motor in the spec class. This is what I am running mine in at my club track and its faster than anything Ive ran thus far. The new Thunder power motor is close and with some tuning may be as fast but so far the D3 is still king.

Did I read that dyno right? The rpm's went down as the current went up?

don't forget that EA runs a load dyno. so torque is a variable as well

Remember electric motors 101;

Voltage = HP (RPM)

Amperage = Torque


Therefor the more a motor is pulling amperage the less the RPM will be because the electro-magnetic field is larger thus harder to spin the armature (rotor) through it.

Hi Guys,

I' like to find out if I need to drop any timing from my boosted esc setup going from a SP v3 13.5 to D3 13.5 and do i run the D3 with timing added on the motor too or leave the motor at 0 ?

Yes what Racecrafter posted is the true definition of why. It easier terms though its as Yang said as I use a Load type dyno so as a load is applied to the motor the rpm drops and this is where the amp draw comes in. As you put a heavier load on it the amps go up and rpm goes down.

What is your ESC setup? I run middle to 1 tick of timing on the motor depending on ambient conditions and the track I am running on.
