For many models in which the Begadi CORE is not yet installed as standard, we offer the CORE for retrofitting via the additional options in the respective airsoft gun offers



Available models with Begadi CORE fitted as standard




CORE icon The integrated Mosfet switches the current from the battery to the Motor with almost no resistance. This allows the motor to use its full potential, which is noticeable in the response behavior and speed. Compared to a conventional switch assembly, 11.1V LiPos can be used here in the long term. The built-in Mosfet can conduct up to 70/240A to the Motor, which is significantly more than conventional Mosfets. This means that more powerful batteries can also be used
CORE icon The built-in microswitch for the Trigger enables very fast firing sequences and can also be combined with Speed Triggers. It is reinforced at the rear to prevent damage caused by pressing the trigger too hard. The trigger travel can be reduced to up to 3 mm. In comparison to optical systems, no shot can come loose here, even in the presence of light, and problems caused by contaminated sensors are also ruled out
CORE icon Compared to some other systems, the Begadi CORE has a classic mechanical safety. This means that it is not possible to pull the Trigger when the gun is secured. This ensures the usual level of safety
CORE icon The Begadi CORE EFC system features cycle monitoring, which means that every firing process is carried out in full. Gearbox jams are therefore not possible, no matter how quickly the trigger is pulled. This also protects the internals from wear and facilitates handling with split gearboxes
CORE icon Another highlight is the integrated battery monitoring and battery cut-off in the latest generation. All common batteries (LiPo, LiFePo, Li-Ion, NiMH) can be used here. Again, nothing needs to be set by the player. To ensure the best performance and maximum protection against damage, the system continuously monitors whether the Gearbox, Motor and battery are within their optimum operating range. As soon as the power supplied by the battery is not sufficient for optimum operation, the system switches off automatically with 2x vibration.

We recommend using 9.9V and 11.1V batteries for optimum operation of the gun. 7.4V batteries should only be used if there is not enough space for a larger one.

If something gets jammed inside the Gearbox or the battery is not sufficient for the setup, the system switches off with 2x vibration. If this problem persists after changing the battery, please contact our support team
CORE icon The intelligent active brake brakes the Motor accurately after the shooting process to prevent double shots and timing problems. The player does not have to adjust anything himself. The system adapts fully automatically to the system and the Springs used. This means that the Motor is only braked as much as necessary to protect it from wear
CORE icon The Begadi CORE EFCS can be permanently loaded with up to 70A. This means that even more powerful airsoft batteries can be used without the electronics going up in smoke.

Here is a small example:
2400mAh LiPo battery with 25C = 60A
2150mAh LiPo battery with 30C = 64A

(Please note: The continuous load is specified here, which is rather unreliable in semi-auto mode)
CORE icon Short load up to 240A possible! Every time the Motor starts, a current peak occurs for a short time. Depending on the battery and the Motor used, this can be between 60 - 150A. The Begadi CORE EFCS can be loaded with up to 240A and therefore still offers a lot of leeway. This is particularly advantageous in semi-mode with fast firing sequences and a powerful battery. High Torque Motors and strong Springs can also be operated here without any problems
CORE icon The Begadi CORE has overcurrent and short-circuit protection. The system detects a short circuit at any time and interrupts the power supply to prevent further damage to the electronics. Even if something gets jammed inside the Gearbox, the EFCS switches off automatically to prevent further damage (2x vibration).
CORE icon The Begadi CORE system is "ready to play " - no adjustments of any kind need to be made, the CORE works as a closed system. This makes it maintenance-free and easy to use for beginners and advanced users alike. Plug in the battery and get started - that's the motto!
CORE icon All systems with a built-in Begadi CORE EFCS come with a DEAN/T connector as standard. This lowers the electronic resistance, thereby increasing the performance of the Motors and reducing heat generation. If you require a different connector system, this can be implemented by our workshop


The Begadi CORE EFCS / Mosfet is not available individually as a regular store item - it is only delivered in installed condition. Customers who already own an airsoft gun purchased from Begadi can have the Begadi CORE EFCS / Mosfet retrofitted by our workshop team at any time and without any problems


Brushless: Our CORE has not been developed or tested for brushless Motors. Unfortunately, we cannot accept any warranty in the event of a defect. If you are looking for an efficient mortor, we recommend our Mamba 19K


Klemmer: Due to the built-in cycle monitoring, a classic Gears jam is NOT possible! However, this does not mean that the Springs or Gears can jam if you have a fault, a bad combination or the wrong battery.
This can occur if a weak or defective battery is used. Avoid operating the Anti Reversal Latch (Anti Reversal Latch) in this condition. Turning back the Gears can damage the microswitch.
