When looking for electronics to power one of our airsoft engines in an AEG to HPA conversion, there are two main components: The trigger board and the FCU (Fire Control Unit). We offer two options: The Spartan Electronics board is a trigger board and FCU all-in-one design. While limited to only V2 gear boxes, the design enables the Spartan to take up less space and makes the system more cost effective and easier to set up. Our Gen 2 Premium FCU is a standalone FCU that connects to a separate trigger board. The Premium FCU allows for more options in fitment, tuning, and fire modes. Check out the information below to see which is right for your needs.
The Spartan Electronics board is a trigger board and FCU all-in-one. The key advantage of the Spartan Electronics board is it’s simple and robust design and lower price point. Settings are primarily manipulated with use of the trigger.
3 Available Fire Mode Presets • Semi / Full Auto • Semi / 3-Round Burst • Semi / Semi *Additional modes available in MTW version.
8 Quick / Easy ROF Presets Select a preset from 10RPS to 33RPS by holding down the trigger as it fires three-round bursts until desired ROF is reached.
12Quick/Easy Dwell Presets Set dwell by holding down trigger as it fires once per second until drop in FPS is noticed, then double-tap to step back up one preset.
The Gen 2Premium FCU is a standalone FCU and requires a separate trigger board. The key advantage of the Premium FCU is a greater variety of available fire modes, more precise setting values for dwell and rate of fire, and an intuitive LED menu with tool-less button style programming.
Set any of 7 fire modes to for each selector position • Full-auto • 7-Round Burst • 5-Round Burst • 3-Round Burst • 2-Round Burst • Single Round • DMR Mode (Semi-auto with 2 second delay between shots)
Precise ROF Setting Set rate of fire to any integer value from 1 to 63 RPS.
Precise Dwell Setting Set dwell precisely from 3 to 20 milliseconds in increments of 0.25 milliseconds.
Additional Features • Short detection • Improved stiction and trigger-reading algorithms
Video transcript: what’s up guys this is rich with Wolverine airsoft and we are very excited to announce the Gen 2 premium FCU from Walter in Arizona now the original premium FCU is the original FCU that we started with there are some key things that you won’t really loved about it how simple it was and robust and things like that but with the gen 2 design what we wanted to do is keep the things the people liked but then add some new features the programming is now completely tooless so you don’t need a screwdriver to adjust the settings it is done with two little buttons and a simple LED menu so go ahead and plug it in here now to program the FCU what you’re going to do is press both buttons and hold them down for five seconds that will kick you into the programming menu once you’re there you can select to tune either your dwell and your rate of fire or your burst mode select well and write a fire then there’s seven yellow LEDs on the right side of the bar act as a fill bar the higher the level the more that bar fills up so you can program it very intuitively just like you could be the original point but in addition that bar correlates to a table which you have which will allow you to look up the exact values your settings if you want to know exactly what your rate of fire is and you can look that up now if we slide our switch down to the burst programming side of the menu there’s another feature that we added on this board the ability to program image select fire state individually so you have the same select seven select fire states that we talked word honor original FCU but now you can select for each fire state which one you want your program any combination of semi and burst that you want one of the most exciting new features that we’re offering on the gen 2 premium FCU is short detection now the short detection monitors the voltage on the solenoid pin and if there is a short on the solenoid wires which is one of the number one things that people do that ruin their part as they pinch the wires or they somehow sort the system it will sense that sort and will cut off power so that Union won’t fry the board like all of our Epson use the Gen 2 premium FCA utilizes full time sleep in order to minimize power consumption and maximize your battery life it’s also backwards compatible with any existing premium FCU or bluetooth absence of unit now on the firmware side of things a few improvements we made include an improved stiction algorithm as well as changes to the trigger reading algorithm to speed up the trigger reading and maximize the semi-auto rate of fire potential the Gen 2 premium FCU has already started shipping with all premium level engine orders so expect to see them showing up at your local retailer very soon for the full set of instructions check out the instructions document in the description below as always thanks for watching guys.
The Gen 2 Premium FCU has built-in short detection. When a short is detected, the LED lights will flash several times and the board will power off. Please disconnect the battery and find/correct the source of the short before powering the FCU back on.
