Mosfet SDU2.0 - Rear Wired [APS]

A micro chip (Super Dynamic Unit) S.D.U. that works together with magnet gears set and micro switch trigger that gives you instant trigger response when shooting.
The newly developed advanced S.D.U. chipset monitors the amperage draw from shot to shot and will cut power to the gearbox if current spikes too high before damage can be done to your replica.
eSilver Edge Gear box works perfectly under 7,4V to 12,5V. The current are always stable at 11 Amps in any voltages between 7,4V to 12,5V. Low and stable Amps means it drains less battery and the lifespan of the components could last longer.
To improve trigger performance, the eSilver Edge gearbox features a micro switch trigger which works together with the S.D.U. chipset for near instantaneous trigger response (as fast as 0,02 seconds). When combined with a short stroked trigger, users can achieve an incredble semi-auto rate of fire.
