"I bought a custom gun off of Ebay with this installed by a likely extremely experienced tech, because this thing worked flawlessly. It has fantastic trigger response, not the best, but it should keep up with any fast trigger pulls in the field. Also, I don't know if it helps, but I'm pretty sure a small FET was installed in my stock as well, after a change to a deans connector. Never over/undercycles when battery is full, great control there. I used about 9.6 lipos with this, worked great. Also the damage protection shutoff when battery is really low/out works fine. I don't understand people's issues with this thing, but if you know what you're doing, buy this. Otherwise if you don't, I guess just buy a GATE Titan or BTC Spectre, of which I'm actually ordering a GATE Titan for my other personal custom m4.
"I just finished installing the ASCU-2 Gen 4 into my heavily modified, Lonex based gun. The install was completely smooth and trouble free. Others here have said that they had to modify the unit to get it to fit into the shell, I did not experience any of that at all. The unit slide right into my Lonex gearbox perfectly! Everything fit like it was made to fit into my gearbox shell. The only modification I made was changing out the small Tamiya battery connector to a Deans connector. Super simple for me.
I have a Lonex A1 motor in this gun and figured that would be considered an up graded motor so I left the anti-reversal latch out of my built and it worked perfectly.
I also had a SPEED trigger already in this gun and so with some minor tuning of the trigger throw I had it set to have an incredibility fast and very slight trigger pull to fire a shot. This system was made to take advantage of the SPEED triggers.
I simply followed all the instructions in the well thought out, English manual that comes with color pictures as well. So often in airsoft we buy stuff that has either useless or non-existent instructions. This fire control unit kit has a very well written (actually a couple typos, but who's counting) and easy to understand manual! Such a relief as there are a couple of things that if you install this wrong you can destroy your unit.
After it was in and the gun put back together I test fired it quite a bit and it worked flawlessly! In a week I will be using this gun at a large MILSIM event and hope to see the full nature of this system in action.
-Easy to install
-Instantaneous trigger response!
-Well thought out system
-3 round burst FTW!
-Needs to have an up-rated motor to work properly and as designed
-Delay between trigger pulls in semi and 3rd burst mode (probably a designed in feature, but I wish it had less delay between pulls. I am nit-picking here.)
"Love this unit! It takes some modification to fit but it works fantastic. At first mine would only shoot half a shot then beep twice. I had new gears shimmed so well that they rotated freely, an M170 Devil Jet motor, and installed the unit correctly and had a brand new FLAME 11.1v Lipo. I contacted ASCU and apparently this is a known issue. All you need to do is cut the notches off the black piece on top of the cutoff sensor unit (it is shaped like an L). The notches push the top and bottom portions of the unit together too tightly and cause the unit to "misread" information gained from the cut off sensor. So once you flatten out that piece, it should work.
-Easy install (modifications can be done with a file and are simple)
-Very good trigger response
-Makes your AEG sound like a PTW
-Protects your battery, motor, and internal components
-Hair trigger mods are easier
-Semi Auto only for DMRs
-Limits how fast you can shoot on SEMI so you do not over cycle
-Good wiring, and plenty long
-Durable motor contacts
-No anti-reversal latch means much smoother cycles!
-$100 for basic functions
-Very large, which is why the modifications are needed
-Wires are big (I had to modify my buffer tube and drill a larger hole)
-Need to shim your gears well, have a strong battery, have a monster of a motor, and have a good AOE to use this thing effectively and safely
Great internal upgrade. Best I've ever installed. 5 stars.
