Ive got the 120 Series SPNO Solenoid in Conundrum Mk2 to switch on the Ev Warrior, and even though its not seen battle yet its handled afew minor tests of the drum.

But if you do go far that solenoid make sure the plastic case is well clamped to the metal base because some of the metal tabs that hold it on have known to come loose.
