Systema To Release New Gearbox And Motor!

Systema have just released some information about a new lightweight gearbox components and also a more efficient motor design.

The new design which come under the name of “Energy” features lighter gears and piston heads meaning less starting inertia and faster response and of course should save energy for longer battery life.

Check out Systema’s official promotional material below, starting with information about their new Energy Gearbox:

ICS Split Gearbox Die Hard Test

This video wants to prove the durable structure of ICS Split gearbox using M120 spring and an 11.1v, 2000mah lipoly battery.

Though I’ve tested an ICS unit without problems using a much stronger Techpro 190 Spring with 11.1v 2000mah, just make sure to change ICS’s stock soft piston body to a more durable one. =)

Prepare for the REVOLUTION!!

UPDATED!! Buckle your seatbelt, as the Revolution is going to hit hard. SYSTEMA is proud to announce new development of a revolutionary gearbox system (for Version 2 guns) that will bring AEG performance level to new heights. Be prepared to experience the SYSTEMA Revolution!




State-of-the-Art Technology — The SYSTEMA Revolution represents the pinnacle of AEG gearbox development while maintaining 100% Ver.2 compatiblity!

» Guaranteed 100% backward-compatible with Tokyo Marui (TM) AEG bodies.
» Direct drop-in replacement for many other AEGs that complies with the TM Version-2 Mecha Box Specification.
»Advanced fire-control electronics and power-regulating MOSFET circuits.
» New loading mechanism /nozzle design.
» Hand-tuned high-output motor precisely matching the new gearbox’s gear ratio.
» Extremely tight manufacturing tolerance ensures superior performance, shot after shot.

Advanced Firing Control— The SYSTEMA E.C.U. (Electronic Control Unit) is a direct decendentof the PTW’s fire control unit, specifically tuned for the Revolution:

»Factory pre-programmed electronic triggersystem.
»Optical sensor array constantly monitors gearbox operation, precisely applying power (and braking) to the motor so that the gearbox will always cycle completely at every trigger pull. This new function entirely eliminates the need for anti-reversal latch.
»Using optical sensor to precisely determine the position/rotations of the gears, the Revolution is also capable of providing the world’s most reliable 3-shot burst operation. No more fiddling with inconsistent “timer based” burst mechanism!
» MOSFET regulated power delivery circuit ensures stable and consistent performance.

Performance and Reliability — Innovation is only half the story. The SYSTEMA Revolution will also far exceed the current standard in terms of performance and reliability:

»New nozzle design eliminates breakage-prone (and decade-old) tappet plates.
»High-strength, all steel gear set ensures reliable operation year after year.
»Full-length steel rack gear greatly extends piston life.
»Top quality components used throughout.
»Factory-backed U.S. warranty when installed by a certified SYSTEMA Gunsmith.

Shimming the Gears

I have been experimenting on different “shim” setups for the past couple of days. Though I made good progress in making the gears work, I wasted 5 or more gears in the process. Thanks to my FRAG buddies, Bobby and Rael for their assistance in closing the damn gearbox and greasing.


Shimming your gearbox is one of the most important things you can do to when working on your aeg gearbox. Proper shimming allows for easy movement of the gears while at the same time reducing the amount of bounce that your gears experience.

Overshimming your gearbox will cause excessive friction and drag on your motor and battery. Undershimming your gears can cause a bouncing action in the engagement of your gears causing excessive wear on your gears and bushings.

This is only a starting point for the proper shimming of your gearbox. Each gear may require more or less shimming. If excessive shimming is needed you may have a deformed gearbox shell.

Below is a diagram from Arnies Airsoft about the different shims sizes you will be using to make your aeg gears work properly.
