Advanced Technology Driven by a powerful PIC18LF2321 microprocessor for both speed and versatility. Uses the latest in ultra-small SMD components and PCB technology to minimize dimensions. On-board supercap and voltage booster allows normal operation under voltage droops as low as 2.5V. Short-circuit, under-voltage, over-voltage(ESD), and over-current safeguards. Advanced thermal management allows the controller to remain cool under sustained firing. Micro-amp sleep current allows batteries to remain connected for many years.

MOSFET Trigger Eliminates damaging electrical arcing of the trigger switch contacts. Lower resistance compared to mechanical switching, increasing motor current. Rated for 100A continuous operation and 400A startup inrush current.

PWM RoF Control PWM RoF reduction to 55%, 70%, or 85% of AEG's base RoF.

LiPo / LiFePO4 Monitoring Monitors LiPo and LiFePO4 batteries to cutoff power before overdischarge occurs. Calculates the cell voltages via the main line, reducing wire clutter.

Trigger Reliability Eliminates the notorious trigger jam on semi-fire, caused by the gears stopping at a certain position. Improved cut-off mechanism prevents the fragile cut-off lever from ever breaking. Semi-fire no longer requires fully releasing the trigger to be able to fire the next shot.

Is the Stealth FET compatible with the ICS V2 split-gearbox?
Yes, it is fully compatible and does not require any modifications to drop into an ICS V2 split-gearbox.

Is the Stealth FET compatible with the VFC SCAR's folding stock?
Yes, it is fully compatible with the VFC SCAR. It will require soldering the two red wires and black wire to the contact pins between the stock and receiver.

Will the Stealth FET disable the trigger lock mechanism when the safety is on?
No, the FET is extremely compact and will not interfere with the trigger locking mechanism of the safety.

What's the maximum RoF the Stealth FET can support?
It has been proven to handle up to 60 rounds per second without a problem. We haven't tested it on higher speeds yet.

With the Stealth FET built on such a tiny board will heat be a issue?
No, the FET is so efficiently designed that any heat is safely and quickly dissipated within the wires instead of the FET itself.

My battery has a output rating of 100A. Will it be a problem for the Stealth FET?
That is a common misconception with batteries. The current being supplied to a motor depends on the load the motor is driving, NOT based on the battery's rated output current. For example: If a setup requires 30A to run, the motor will only draw 30A from the battery regardless of the battery's output rating. Since 99.9% of AEG setups draw less than 50A, the FET's 100A rating is already more than necessary.
