im staying with my Novak....
I see what you are saying, and it can and will be confusing until its more sorted and worded differently...
just remember if anyone goes outside the box....make sure your ROAR motor meets the requirements as posted....some companies have a habit of making a "goof" when looking for that "W"
not legal....but is a Trinity
Team Trinity D4 1S "Certified" Short Stack Brushless Motor (25.5T)
part#TRITEP1704RXX
legal Trinity.....
Team Trinity 24K Short Stack Brushless Motor (25.5T)
part#TRIREV1804
so make sure you check your part numbers and it wouldnt hurt to check your stator and rotor
IMO

Does anyone know if HobbyKing has submitted their V2 25.5T for approval (or plans to) ?

What "weight" (CST?) diff fluid do you guys run? I've read as little as 1,000CST, and as high as 10,000. Will it depend on how tight the track is? More CST for tight short tracks, or less CST, or....? How does this stuff work?

We need at least 18 cars to "keep" the class, or, it gets dropped.

Higher viscosity oil in the diff has two major benefits: it adds stability while trail braking (simultaneous turning and braking), and reduces on-power understeer (while accelerating out of a corner). The drawbacks are understeer on corner entry and lower mid-corner speed (especially in sweepers or corners where the car is not at its limit of lateral acceleration) due to tire scrub.
If your car is tail-happy while turning and braking, try going to higher viscosity. If it understeers going into corners and oversteers coming out, try going to a lower viscosity.
Generally speaking, lower-traction surfaces require lower viscosity, and higher-traction surfaces can use higher viscosity.
I have used anywhere from 5000cst on very slick tracks, up to 50,000cst on medium-high grip tracks.
I have found no benefit of using any substantial viscosity in the rear differential; just a little lubrication works fine.

Lighter rear fluid promotes faster rotation and more rear grip on corner exit. Thicker fluid slows the rotation down, wanting to keep the car straighter, also can help prevent certain types of traction rolling (namely on black carpet).
Very roughly:
If you're car feels like the nose is turning into itself too much or hard to track straight in quick little chicanes, go heavier.
If the rear is loose on exit, go lighter.

Measured my Novak and 24K motors using the not as good as what ROAR uses, Fantom tester for resistance:
Novak: 109
24K: 105
Novak: 109
24K: 105

Yes, the Fantom tests them as well.
I have two novak rotors:
1 -1237/1244
2 -1205/1234
Still have to test the 24k rotor
Also tested on motolyser
24k on left novak on right
RPM 12919 14450

Assemetry 4 1

[QUOTE=John Wallace2;14639531]Your 24K looks good compared to mine. my rotor asymmetry is 7 and one senor is off by nearly 9 degrees. I've run Trinity based motor for most of my 30+ year RC career. I've never had such a P.O.S. as this![/QUOTE
A friend adjusted the sensors on my 24K so that they are now more in line with what JayL has on his Novak (deviation is exactly the same). When I get the motor back tomorrow I'll set the timing at 50 degrees and see how it compares to JayL's Novak in terms of AMP draw, RPM and KV. Hopefully adjusting that one sensor will affect the asymmetery number too.

I got the 24K motor back and adjustd the average timing to 50 degrees to compare with JayL's results. I ran these on my G Force tester.
Sensor timing 50, 48 and 50 (remember the b sensor before being adjusted was way off: 7-9 degrees higher than the other two sensors).
Results: My24K/JayL24K/JayLNovak (All at 50 degrees average timing
KVA 1816/1746/1955
RPM 13802/12919/14450
AMPs 2.6/1.88/2.05
The 24K is looking better vis a vis the Novak, but it is still box stock with the exception of the sensor adjustment. I'll check the rotor later and add to this post.
