Kestrel V3 SE Mosfet Unit [ESHOOTER]

Eshooter Kestrel V3 SE MOSFET by Eshooter is a programmable electronic unit designed for AEG replicas with a V3 gearbox. The model uses configuration via the Eshooter App, brushless motor support and advanced protection functions, supporting faster trigger response and precise adjustment of the replica's operation to the user's play style. The SE version retains the key features of the Kestrel series in a design prepared for modern configurations based on the V3 gearbox.

Electronic system

Eshooter Kestrel V3 SE replaces standard trigger contacts, taking over control of the replica's electrical system. The ETU directs power from the battery straight to the motor, supporting responsive operation and smoother mechanical performance during shooting.

The unit uses gearbox cycle detection through a gear sensor. The system allows the user to select a configuration for standard gears, HSG or DSG, making it possible to adjust the electronics to the specific mechanical setup of the replica.

Programming and operating modes

Kestrel V3 SE allows parameters to be configured through the Eshooter App. The user can save up to 3 setting profiles, rename the device and switch between saved configurations using the trigger in SAFE mode.

The unit supports various selector modes, including SAFE, SEMI, BINARY, BURST, AUTO and SNIPER. The Sniper Delay function allows the delay between shots to be set to 0.5 s, 1 s, 2 s or 3 s, supporting configurations that require a controlled rate of fire.

Pre-cocking and replica operation control

The pre-cocking function offers 200 adjustment levels, allowing more precise tuning of spring tension before the shot. This setting helps shorten trigger response time, especially in configurations prepared for dynamic shooting.

The unit also features ROF Control, which allows the replica's rate of fire to be limited according to the user's preferences. The active brake works adaptively, supporting more stable stopping of the mechanism after each cycle and reducing the risk of unstable gear operation.

Protection and diagnostics

Kestrel V3 SE uses an intelligent fuse and protection functions that monitor the battery, motor and controller operation. The system reacts to overload, short circuit, overheating and lock-up, supporting safer operation of the electrical system.

Battery protection monitors the voltage of LiPo and LiFe batteries, helping reduce the risk of over-discharge. The app can send a low battery warning, making it easier to control the power source during replica use.

Power supply and operating compatibility

The unit supports LiPo, LiFe and LiHv batteries in the voltage range of 3.75-17 V. The manufacturer also indicates support for brushless motors as well as high-speed and high-torque motors, allowing the Kestrel V3 SE to be used in more advanced AEG configurations.

The wires are made with high-temperature-resistant Teflon insulation, and their cross-section exceeds 1.0 mm2. This construction supports stable current flow and reduces the risk of insulation damage during prolonged operation of the unit.

App functions and updates

The Eshooter App allows sensor calibration, setting adjustment and firmware updates through the wireless software update function (Over-The-Air). It allows EShooter Kestrel ETU modules or other devices from this brand to be updated using a smartphone. This helps improve operating culture, increase calibration precision and add new functions without using cables.

Remote software updates help keep the unit aligned with features developed by the manufacturer without the need to replace the electronics.

After one hour of inactivity, the unit enters sleep mode, reducing battery consumption during standby. Reconnecting the battery restores device operation.

Operating parameters

The unit is designed for AEG replicas with a V3 gearbox. The module operates in the voltage range of 3.75-17 V, and its current draw is 17 mA. The manufacturer specifies the operating humidity level at ?80%.

Manufacturer

Eshooter is a manufacturer of airsoft electronics and accessories, developing ETU units, tracer units and solutions supporting AEG replica configuration. The Kestrel series was prepared for users who want to upgrade their replica with a programmable control unit, protection functions and app-based configuration.
