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 offers of the airsoft weapons.

When retrofitting, the warranty is also increased to 4 years for these models

built-in Begadi CORE




CORE icon The integrated Mosfet switches the current of the battery to the motor almost without resistance. This allows it to use its full potential, which is noticeable in the response and speed. Compared to a conventional switch assembly can be used here in the long term 11.1V LiPos. The built-in Mosfet can conduct up to 70/240A to the motor, which is significantly more than standard Mosfets. Dadruch can also be used stronger batteries
CORE icon The built-in microswitch for the trigger allows very fast firing sequences and can also be combined with speed triggers. It is reinforced in the rear area to prevent damage caused by pulling the trigger too hard. The trigger travel can be reduced to up to 3mm. Compared to optical systems, no shot can come loose here even when light falls on it, and problems caused by contaminated sensors are also ruled out
CORE icon Compared to some other systems, the Begadi CORE has a classic mechanical lock. Thus, when the weapon is secured, it is not possible to pull the trigger. This provides a familiar security
CORE icon The Begadi CORE EFC system features cycle monitoring, which means that every firing operation is fully executed. Thus, gearbox jams are not possible, no matter how fast the Abuzug is operated. This simultaneously protects the installed internals from wear and facilitates the handling of split gearboxes
CORE icon Another highlight is the integrated battery monitoring and battery shutdown in the latest generation. All common batteries (LiPo, LiFePo, Li-Ion, NiMH) can be used here. Again, nothing needs to be adjusted by the player. To ensure the best performance and the highest protection against damage, the system continuously monitors whether the gearbox, motor and battery are in their optimal working range. As soon as the delivered power of the battery is not sufficient for optimal operation, the system automatically shuts down with 2x vibration.

For an optimal function of the weapon we recommend to use 9.9V and 11.1V batteries. 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 will also shut down with 2x vibration. If this problem persists after changing the battery, please contact our support
CORE icon The intelligent active brake, accurately slows down the engine after the shot is fired, preventing double shots and timing issues. Here, nothing needs to be adjusted by the player himself. The system adjusts fully automatically to the system and the spring used. Thus, the engine is braked only 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 stronger 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: Here the continuous load is given which is rather unreleavant in semi-auto mode)
CORE icon Short load up to 240A possible! Every time the motor starts, there is a current peak for a short time. This can be between 60 - 150A depending on the battery and the motor used. The Begadi CORE EFCS can be loaded here with up to 240A and thus still offers a lot of leeway. This is especially advantageous in semi-mode with fast firing sequences and a strong battery. High-torque motors and strong springs can also be operated here without any problems
CORE icon The Begadi CORE features overcurrent and short circuit protection. The system detects a short circuit at any time and cuts off the power supply to prevent further damage to the electronics. Even if something should jam inside the gearbox, the EFCS automatically shuts down to prevent further damage (2x vibration).
CORE icon The Begadi CORE system is "ready to play " - no settings of any kind need to be made, the CORE works as a closed system. So it is maintenance free, easy to use for beginners & advanced users alike. Plug in the battery and get started - that's the motto!
CORE icon All systems with installed Begadi CORE EFCS already have a DEAN/T plug as standard. This lowers the electronic resistance and thus increases the performance of the motor, as well as reducing heat generation. If you wish a different plug system, this can be implemented by our workshop
CORE icon Made in the EU under the highest quality standards! Due to the high resilience and manufacturing quality, we grant a 4-year warranty on all Begadi CORE systems! Should there still be a problem, our support is available immediately.


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