Professionally made mosfet with active braking, which can be disabled by removing the red jumper. The device is designed to replace the microswitch in certain V2 gearboxes with no modification required. In semi-auto mode the piston isn’t partially cocked, the spring is fully released, parts in the gearbox aren’t under strain and the nozzle has a more effective seal with the hop-up chamber (dependent on ROF). Active brake solves multiple shots in semi-auto with weapons with a very high rate of fire (ROF). The device increases the rate of fire and the battery holds longer than with basic wiring.

SPECIFICATIONS:

• Easy installation inside a V2 gearbox 2, replacing the microswitch
• Comes without wires, you can use max. 1.5mm (AWG16) power wires and 0.5mm (AWG20) signal wires
• Disable active braking by unplugging the red jumper, when your gun has a Rate of fire under 20bb/s, otherwise, it could lock up the trigger on SEMI due to low gear speed.
• The motor will be under less stress without active braking.
• Designed for springs up to M160 (equivalent for current 75A single shot fire or 25A burst fire for max. 30s)
• Specified for common batteries up to 17V (Ni-xx 8.4 – 12V, lipo 7.4 – 14.8V)
• Active braking uses excess energy from the motor to stop it. The braking effect is the most powerful with high-torque motors
• In full auto mode, the piston stops in a random position due to the gearbox design
• For correct function, it is necessary to have a functional cut-off lever, selector plate, anti-reversal latch, trigger and trigger block.
