Inductance and or resistance
Do guys meter your arms? What kinda numbers should i see from a good arm? stock or mod (depending on turn in mod motor) whats good for what turn motor?

so i take it nobody has measured anything like that??

Any 1 of these factors can affect Inductance:
-size of wire
-total length of wire
-single, double, triple etc
-type of lamination blanks
-what's been done to the laminations (eg drilling, truing)
-type of stacking of those blanks
Theory says lower inductance is "better" however that's only
comparing between two identical arms from the same model
of motor from the same manufacturer.
Comparing inductance between 2 different model arms
don't make any meaningful sense.

WC- That why I clearly stated depending on Stock or Mod or turns. Comparing the numbers between the same type arm make alot of sence. Maybe comparing a trininty 12 double to a trinity 12 double flat wire or trinity stock to a orion stock etc etc etc...I guess im way to technical in the small parts. But the things i look at equil mega hp...i take it yall dont match mags either? Im talkin within 10 points off

To a degree, checking inductance on modified arms, is kinda pointless, since they are handwound....they should be nearly idenctical, assuming all things equal....
However, checking stock and 19t arms can be worth it, but I would only did it at a big race.....for club level racing, its not really worth the time....
The only way to correctly check is with an LCR meter.....multimeters or voltmeters won't work correctly. You can buy a sweet LCR meter for about $100....
