ASCU technical discussion

The front section of the lower, under the mag catch guide continues up to the end of the mag catch guide.

The rear part of the upper mechbox is a bit longer than a regular mechbox upper part. The top is also at least twice as wide.

The receiver is a bit longer at the rear near the buffer tube to allow the lower upper mechbox to clear. The buffer tube guide is also threaded at the tip to allow the wires to pass in and to let the mechbox open.

I will post a side-by-side picture of a TM mechbox shell and ICS mechbox shell. The lower mechbox is exactly the same as any V2, every hole placement is the same. The top of the lower mechbox is also grinded ruff, suggesting that they use a V2 cast mold with a plug, and then clean off the burrs.

I thought the trigger mech was different and that was why Airsoft Systems was designing one especially for the ICS gearbox.

Very little. The trigger guide hole at the top of the shell is about 1mm lower than on regular AEGs. You can see that this hole is made elongated in the trigger module to accommodate for various brands of mechbox. It definitely fits with very little to no fitting. A normal trigger will have issues with the contact block because since the ICS trigger is made lower, an other one will rub too hard with the trigger and jam when the dis-connector engages.

Was over at Jugglez yesterday...

ASCU fits perfectly inside the MadBull ACE Skeleton stock (long). It also fits the 9.9V Intellect LiFe battery. Very good option for people running a full stock but want to make things a bit more compact.

A couple minor modifications required in my setup:

1. Extended the motor wires to position the ASCU in the butt plate area. The control wire is the perfect length.

2. Opened the channel for the wires on the receiver end.

3. Slotted the stock's attachment disc so that the wires don't have to run through the tiny hole they supply.


pictures up later.

any doctors want to state what they charge for installation?

i have been charging $50-$75 depending on what custom dremelling must be done. this includes deburring mechbox edges and wire channels, followed by a solvent cleaning and relube.

is this high, low or in the ballpark of a fair rate?

That's about right for all the work involve.

I'm flat 20 per hour + parts.

ASCU normally go in within about an hour

30$/h + parts here, but I sometimes do a 20$ flat for small thing (changing a spring for example)

I just installed another ASCU. It is the first one to give me trouble.

When I put the selector on auto it just shoots away without pulling the trigger.

In semi-auto it fires once without touching the trigger and then stops. Then you can use the trigger to fire in semi, but if you switch to full auto it just goes off on its own again!

Anyone experience this problem?

Seems like the button switch is defective.

Thanks for input.

[HKGhost]

if it fires on it's own, the ASCU is defective. I had one like that. It would just fire when the battery was plugged. Return it and get a replacement.

[venture]

Thanks ghost, just what I thought. Jugglez will take them back will he?

In semi it beeps after every shot.

[HKGhost]

if it beeps after every shot, it's the cutoff lever I believe. On one of my build, the cutoff lever stick out too far (the side with the selector plate) and would rub on the body. This caused the ascu to beep after every shot. check that out first.

When I just disassembled it I noticed a bit of insulation off at the bottom of the gearbox on the red wire. It may have been shorting on the gearbox shell. Would that cause this problem?

[venture]

I just reassembled with a new trigger unit. Works great.

[HKGhost]

a short can cause the unit to malfunction but if it's just one wire that lost some insulation, that can't cause a short. When the gun fires, is it when you plug in the thin gray wire or just when you plug in the batter without the gray wire plugged in?

[venture]

no it will only fire with the ribbon cable attach. even backwards.
