Hahaha 1.2million Volts ...i think the one more in danger are the RC drivers that might get hit by the tazer or stun gun
I may sound crazy but i think the tazer nor stun gun wont have any effect on an RC build unless you hit the wiring or ESC heatsink or the motor. For the small current to take effect the 2 contact must have a full short or closed circuit. I maybe wrong though...I just remembered mythbusters
