12S/EC5/Jivev9: Spark Arrestor Necessary???

Who is using a spark arrestor with a 12S setup using EC5 connectors on a Jive V9 controller?

I am not on this one as it seems the spark is just not that bad for some reason. Maybe it has an internal one? I need to look @ the specs........Ron

Also a spark arrestor can prevent the ESC from calculating the correct amount of cells / voltage.

Upon powering up an ESC through an anti-spark circuit, the startup beeps can generate a "boost"(through motor inductance) which can create voltage spikes. Since the battery is not present to absorb them, it IS possible for these spikes to damage the more voltage sensitive components on your ESC. This is why it is necessary to use very low Ohm resistor's. Minimizing the amount of time the ESC is powered through the anti-spark circuit can also help. And like it has already been said, an anti-spark circuit can lead to the ESC miscalculating cell count, although I know of NO ONE that uses their ESC's auto cut-off feature in their helicopters.

IMHO, the MAIN benefit to using an anti-spark circuit on an ESC is to preserve the condition of your connectors. Bullet style connectors are less prone to spark damage, but Dean's users(like myself) will benefit more from an anti-spark circuit. Since you are using EC5's, you will probably be fine without one.
