Kestrel V2 Basic ETU – Advanced control and reliability for your airsoft replica

The Kestrel V2 Basic ETU from Specna Arms is a highly advanced ETU system with integrated MOSFET that is characterized by its ease of use, durability and versatile functionality. This system can be programmed easily via the trigger and is suitable for both brush and brushless motors, so it works optimally in high speed and high torque configurations.

Kestrel V2 Basic ETU System Features:

• 5-stage preload: Programmed preload with learning function for optimal positioning of the piston - ideal for responsive firing.
• Calibration function: Automatically calibrates after connecting the battery by firing a few individual shots to precisely adjust the piston position.
• Shot cycle: Each shot is executed as a complete cycle, which reduces the load on springs and mechanical parts and extends the life of the replica.
• Blocked rotor protection: The rotor protection protects the inside of the gearbox in the event of motor damage and prevents costly repairs.
• Battery discharge protection: Warning signal through motor vibration and flashing blue LED (5 times) to indicate impending battery discharge.
• Undervoltage and overvoltage protection: Automatically adapts the system to different battery cells (6 V to 17 V) for stable and safe operation at different voltages.
