Sensored for 8th scale?

I do agree with you that if you put a sensored Aveox on it, the performance would be much better. Why bother though.

And how is that different? Kv ratings are given for the motor without load, otherwise you need to call it different and specify testing load. In general Novak's electronics are designed very well, but motors and software sometimes not.

What you mean by "Why bother though"? Have you read this thread...

GriffinRU, are the aveox motors sensor wires the same as novak's? I mean can I just plug an aveox motor into a novak esc?

You need to make some modifications to match HV interface.
Here what HV expects:
Pin #1- Black wire-ground potential
Pin #2- Orange wire-phase C
Pin #3- White wire-phase B
Pin #4- Green wire-phase A
Pin #5- Blue wire-temp control, 10 k Thermistor referenced to ground potential
Pin #6- Red wire-+ 5.0 volts =/- 10%

Aveox motor has only 5 wires, A/B/C/Power/GND. I do not remember, right now which one is which, but if you have manuals or motor itself it is not that complicated. Then substitute thermistor with pull-up resistor to set 2.7V reference.

"and how is that different?" not sure what you meant by that?
I understand how kv ratings work, I'm just saying that the person I know said don't compare our 4400kv listed to that of other common brands like Hacker because they are testing it a differnt way. He said the acutal kv on that motor would be less if it was tested the same way everyone else was tested. I have the motor, and no way it is 4400kv. I would guess between 2500-3000 is more accurate.

Why Bother- That meant why would you buy an HV system and buy an aveox motor to replace the novak motor, it just doesn't make sense to me. You would be so deep dollar wise, and still not have that great of a setup. Why not just buy something else.

Guessing is not a precision tool. And just because it doesn't get to its rated RPM in emaxx (very well known reasons), doesn't mean that it doesn't have Kv=4400. So, until you have proven data which shows that Novak's info incorrect, I will stay with Novak's data. Motor is motor and it doesn't need to be Hacker brand or like to agree with theory of operation and physics, if you wish.

Dollar wise everything is possible and e-bay is not a bad place. Soon you can get sensored motors from Feigao as well. So $250 HV-Maxx plus $60-90 Feigao (S/L/XL) Motor...

Artur
P.S. Personally, I think HV-system was designed by two different teams. While Team responsible for ESC did amazing job, motor group screw them up big, forcing them even create last minute fixes in program to make somehow system operational at all. Too bad nobody will tell you the real story... :)

Stating the obvious, "guessing is not an accurate tool" of course it is not that is why it is called a guess. :007: Also, where did I base my statement off the motor not reaching a specific RPM in a Emaxx??:032: If you read my post you would see that I was not questioning the kv based off my guess, but instead off of the word of one of the R&D people that work at Novak. You can see I live in So Cal, so not too far fetched to believe that @ So Cal raceway(my home track) I might know a few people that work @ Novak seeing this is their home race track also. You believe whatever you want, but I will choose to believe a Novak R&D person over you.

Magnetic field is stronger in So Cal...

In general Kv number represents motors RPM @ given voltage with "0" timing.
Timing can change Kv number significantly and while most BL controllers allow you to change timing or adjust it automatically for you, Novak's ESC has this value fixed (possibly in 2 values). So as system it can perform poor, but on paper with correct timing and without load Kv=4400 can be guessed. Otherwise it is false advertisement and all Novak HV-Maxx systems can be re-called :)

You can get aveox pinout from PCB.

Awesome! How does it run?

Runs great. It is kind of problematic to run Novak in Forward/brake/reverse mode, even if you set reverse to only 45-50% it is still hard on going from reverse to forward. So, I'm running in Forward and brake mode only.

It is only 7.7 lbs. without body.

1/8 scale and what is that?

[MetalMan]

That doesn't look so good... Are you sure the front diff was shimmed properly?

[Serum]

You sure it didn't get loose from the diff?

is this because of the too hard brakes?
