Page 99:Miles said:Interesting to see the variations in specification for the CA 120.....
Can thickness - 2.6mm
Magnet size - 30 x 10 x 2.6mm

"As such at a given mechanical speed, the Turnigy with 14 pole pairs will have 40% higher eddy current losses than the Plettenberg with 10 pole pairs. This may be significant, especially at high RPM"
I wonder if they put a bit more amps on Ca (since it has 3x more copper than the predator), less volts (same power), wouldn't it up the efficiency on the motor...
Didn't quite understand why the new CA is so much worse than the original, could anyone expand their thoughts?
edit: Never mind last question, already saw the no load comparisons between old and new CA's
