QUOTE im thinking of upgrading to turbo (resistor) is it worth it?
WTF is a 'turbo' resistor? Or do you mean Professional resistor?
If you mean a professional resistor: My *understanding* is it is just better at heat dispursal. It's only worth the upgrade if you are running Heavy mags, OR often have the throttle hovering between min and max, OR race in endurance or >1 hour stints.
Then again, it may be more reliable in the long run??? I would say however if you already have a controller you are confortable with, it's not worth upgrading/changing until something goes wrong with it.
