Default 17.5T Motor - Which is better?

OK, the question I have is which 17.5T motor is better out of the following:

1-Novak SS Pro
2-Team Epic Duo 2
3-Team Epic Duo 3
4-Novak 3617 Ballistic Spec

It will be powered by a Hobby Wing Xtreme Stock Brushless ESC, so what would be a better choice? Thanks guys (and girls if you lurk round here )

the absolute hands down best motor is the one that I chose to use at that moment, same for esc, chassis, tires, body, servo, and everything else I have.

there is NO best anything. its all in what you "think" is best and what works for you.

Hahaha I like your thinking, so far I like the Epic Duo 3, and 1-3 are all the same price, #4 being a little more expensive, but not by much.

I'm enjoying my ballistic 17.5 right now. It seems to pull a bit on the guys that run speed passion / orca, but that could be gearing too.

I like the sensor port on the side, seems like extra security.

Today, I removed a 13.5 Duo 2 from my 1/12th car and substituted it for a 13.5 Novak Ballistic. Got an immediate 1.5 seconds reduction in lap times.

Well then out goes the Duo 2
So far Duo 3 has the lead, then the Ballistic.

Any opinions on the two?

Are you comparing apples to apples? The Novak motors come from the factory set to 30 degrees timing on the motor. Aren't the Duo2 motors around 24 degrees timing when the endbell is set to the indicated 0 degree mark? Would a gearing or motor timing change have resulted in the same lap times? If your lap times changed that much, you probably weren't setup correctly for that motor's "sweet spot".

After you have run a motor (any mfgs' motor) for a while, you may have weakened your rotor magnet. Using dynamic timing escs can demagnetize your motor because of overheating. Installing a brand new motor (new rotor) should should make your car run better; but, replacing the rotor in your existing motor will probably make your "old" motor run better, too...

That's good to know. Is there anything else in regard to the motor that deteriorates over time?

Not sure that motor components "deteriorate", but chronic overheating can damage or even burn up your stator, magnet and even the timing assembly.

BL motors should be maintained and bearings checked regularly:
