17.5T Motor - Which is better?
#16
Well, I'm still going to get the Duo3. I know that it isnt the motor that makes it fast, but how fast you can make the turn cleanly. Coming from 1/10 nitro I, and many others, think that I would do very well in 17.5. I hope they are right as well as myself, just have to get the setup right for my style of driving
#17
its funny when people buy new motors and think they are faster. ANY fresh motor is always going to be quicker than an old well used motor
#18
Not always true. My worn out speedpassion will still out run a brand new pluses. BTW I'M STILL WAITING ON MY REPLACEMENT

Correct. Just because two motors are wound the same doesn't make them anywhere close to performing the same. Heck, a worn Boss tuned SP beats a fresh SP, for that matter. It's all about how deteroriated it is or is not, and the better motors start at a better performance mark than the entry level products, so even if they fall off a little, they're still more capable performers than fresh, but lower standard, motors.
As another example, a Novak 17.5 SS is a 130ish watt motor with out of the box timing, while an LRP X12 17.5 is a 180ish watt motor with the same out of the box timing.
The X12 has a -10 to +10 degree additional MECHANICAL timing adjustment, which opens up the performance gap between the two even more.
Both can be had, new or used, for about the same price when shopping on eBay auctions (notice I did NOT say the "Buy it now" options). I don't care what the MSRP difference is, or the difference in price at your LHS. Shop the market, unless for some reason you just have to have it NOW. MSRP they're different classes of motor, but in the real world......well, it's your money, use it however you like.
Dollar for dollar spent, there's no doubt that the X12 is the better/faster motor that will allow you to change timing physically, endure electronic timing/boost, and provide room for overall growth as your skills progress.
Oh, the more capable motors will hold their value better when you go to trade in/up or sell it off.
Even a beat X12 will best a fresh Novak SS. I've seen it and lived it swapping one for one in the same car (and YES, gearing and all was adjusted to accomodate the different requirements of each motor, and work done to optimize the set up for each!).
Nothing wrong with entry level products, just expect entry level performance. Whatever you opt for, the more features it has, the more potential it has. The rest is up to you!

You can also design your own custom motor:

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 plastic color insert designating the spec wind is attached to the wound stator; click drop down stator wind to change colors:

Running a BL motor at temps exceeding the mfgs' guidance can melt the coating on the stator wires and cause the wires to short out; in addition, high timing blasts can intermittently overheat the motor. This type of overheating can not be checked with a temp meter and can damage the stator and demag the rotor.

Most of the local racers at our track have moved away from the X12 as it gets hot, can blow up easy and generally is not any faster than any other motor. SP is starting to take over.
I can imagine teh X12 may would be good for 0 timing racing though.

So, your advice is, "Don't run it too hot", whatever that is. Just curious, what is your number for temperature which is not to be exceeded and is it different for each motor type/wind you produce?

This just doesn't make any sense. You (Novak) can specify a temperature (manufacturers guidance) that should not be exceeded, but you cannot not give your users/customers a tool or other information that will allow users/customers to meet that guidance/requirement. You are only providing information that results in users trying to guess if their motor is overheating.

NOTICE TO NOVAK BRUSHLESS MOTOR USERS
Novak motors have been designed to handle the rigors of any form of electric racing, from touring cars to off-road trucks and buggies.
Through multiple forms of testing, customer reports and inspection of damaged motors, we have determined that the maximum external safe operating temperature for Novak brushless motors is 175 F (80 C). Motors that run at higher temperatures have sustained internal damage.
This internal damage can render the motor inoperable if you continue to run it and will ultimately result in burned or melted coil(s) inside the motor. This type of damage to the motor is not covered under Novak’s product warranty.
From our testing and experience, keeping the external motor operating temperature under 160 F (72 C) will provide the best performance when the car is handling well. At this temperature, the motors’ racing life will last a long time and should require only occasional replacement of the bearings and rotors.
Precaution about Advanced Timing:
Use of Novak brushless motors with ESCs that have advance motor timing can result in excessive current draw, which will increase the motor temperature above the safe operating temperature. As most of these ESCs do not have a thermal overload protection for motors, continued operation will result in internal damage to the brushless motor.
This type of damage is not covered under the product’s warranty.
Precaution about Over-Gearing:
Motor temperature is the ONLY way to properly set the vehicle gearing. Over gearing the motor will result in excessive operating temperatures, which may result in internal damage. This type of damage is not covered under the product’s warranty.
All Novak Motors are hand-wound, assembled and tested at the Novak’s facility in Irvine, Calif. Each motor (yes, 100%) is meticulously inspected and tested for internal shorts, as well as run extensively before final packaging.
Please follow these important operating temperature guidelines.
Thank you.

each motor has a different temp range that is "ok" novak says 175, I have gotten there motors over 200 and killed the rotor, the x12 its just getting started at 200 and doesn't mine it at all, its not faster, just prefers a diff temp range, I remember back when SP released the first 10.5 motor they said the hotter the better, well up to a point, ( the first 10.5 was a turd). when properly tuned 2s sedan with or without boost i like to be around 150. my 1s cars don't even get warm to the touch.
wow, talk about off track and subject..

I'm can find both at 2200kv according to manufacturers specs.

There is no standard industry method or rating the watt output of a motor. Companies can claim whatever they want.
I do applaud NOVAK for at least giving us the variables of how they get their watt specs.
I do not claim any watt specs on my motors. If I claim lets say 150 watts, and another brand claims 270 watts, instead of questioning the data, most people think that the supposed 270 watt motor is faster!!!
Silly people.
My 550 watt 17.5 motor and 120c battery make my car the fastest!!!
LOL.
