Ok. I'm new here. New in this world of RC so don't bite my head off if the questions are a bit simple or have been asked already. [sm=spinnyeyes.gif] (I HAVE been reading.)

BRUSHLESS SYSTEMS. IS ONE MORE EFFICIENT THAN ANOTHER?

I kind of understand the kv rating of motors in that the higher kv motors have higher RPM and less torque. I'm still unsure about the conection between number of turns and kv values. Will a 10 turn motor always be rated at 3500 kv? Also, reading says that a motor with more turns will be more efficient than one with fewer turns. Is this ture, and if yes, WHY? Taxxas' manual for the VXL system (pg8 under kV Rating) says "As the kV increases, the current draw through the electroncis also increases."

My curiousity stems from the coments from members here that with the Traxxas VXL system, batteries 'die fast'. I've read nowhere that 'batteries last forever'. This review of the mamba max 5700 system puts runtime with an IB 3800mAh pack (6 and 8 cells) at around 30 mins. I'd assume that since the VXL is a 10 turn motor, it should have a little longer runtime if used in the same vehicle. What's your opinion/ experience?

Are all magnets and wires created equal? There's a sintered upgrade kit for This novak system I shudder to think that the original rotor consists of bonded Neodymium. Does any motor use special wires to have ultra low resistance?

How significant is the performance of the ESC? I see that the VXL has a resistance of 0.00075ohms while that of the mamba max is 0.0003ohms yet, the VXL supposedly handles 200A continuous while the MM 100A continuous.... What gives? The VXL advertises 'transistors' while the MM advertises MOSFETs. I know MOSFETs can haldle high currents. Are they just using different terms to describe the same thing or is the VXL using older technology and exaggerating the specs?

What's your experience?

Thanks for the patients!!
