PERFORMANCE UPGRADE
HIGH FPS UPGRADE
TM AEG: a baseline for performance measurement
What is proper usage?
What are the key elements of a high FPS setup?
Version 2 mechbox versus Version 3 mechbox: any difference in
stock performance?
FPS increase in meter readings VS performance increase in a
practical sense: the law of diminishing marginal gain in
performance.
0.20g BBs versus 0.25g BBs versus 0.30g BBs: the heavier the better?
Does FPS always go hand in hand with Joule?
What is the difference between the FPS system and the Joule system?
How do you use FPS to measure Joule?
How do you use FPS to give an estimate of the range?
Higher FPS = lower ROF?
Softer spring = Higher ROF?
Harder spring = Lower ROF?
Is 8.4V insufficient for an upgraded mechbox?
Does battery size matter?
Is battery power important for semi-auto firing?
EG-700, EG-1000 and ICS Turbo 2000
Why (and why not) should I buy the high torque gear set?
Why (and why not) should I use helical gears?
Why (and why not) should I keep the stock plastic bushings?
Why (and why not) should I replace the stock plastic bushings with
metal bushings?
What is an easy way to (more accurately) shim?
How do I tell if shimming has been done correctly?
What is the recommended order of gear insertion?
Longer spring versus shorter spring: the longer the better?
What are the major parameters of a spring?
Is a harder spring more harmful for the internals?
Installing a long spring: tricks and potential danger.
Installing a short spring: tricks and potential danger.
Why (and why not) should the spring be ground?
How to facilitate spring spinning?
What is a variable pitch spring? Is it always better for AEG?
Use of spacers for spring compression: tricks and potential danger.
What is wrong with a custom made spring?
Systema Springs versus PDI Springs
Can stainless steel spring offer better FPS?
Can Telfon Coated spring offer better FPS?
The long variable-pitch spring is very difficult to install. What
should I do?
What can I do to reduce stress on the gears?
Can an EG1000 increase FPS (through higher torgue) over an EG700?
Why (and why not) should I use a Bore-Up Cylinder?
Why should I replace the stock cylinder on my G3 SAS?
Different guns use different cylinders that have different number
and position of openings. Why’s that?
Is it useful to block the cylinder opening altogether?
Why is it useful to put holes on the piston head? Any alternative?
Why (and why not) should I use a metallic piston head?
How about a silent head set?
Is aluminum piston more durable?
Is version 2 mechbox too fragile for M130 or above?
Do I need a heatsink motor plate on upgrade that involves M140 or
above?
How do I effectively reduce heat on the motor?
Why (and why not) is the one o’clock gear timing an issue?
Can I still use the smaller batteries to power my upgraded mechbox?
I want to hide my battery inside the grip and the stock but the
battery cells are too big. What should I do?
Chaining up your batteries: Parallel VS Serial configurations.
Should I use Sanyo battery cells for maximum performance?
How safe is it to remove the fuse? Any alternative?
Why (and why not) is it necessary to replace the stock wires?
Why is it necessary to shorten the wires? Can I use stereo wires
instead?
Why (and why not) is it necessary to replace the stock Tamiya connector?
Are NiCd batteries superior to NiMH batteries for driving upgraded
AEG?
How do I optimize the overall performance of the stock motor?
Is it possible to increase the torque of the stock motor? If so, how?
What else should I buy for a high FPS configuration?
What is wrong with the soda can test?
What is right with the soda can test?
What is the most accurate way to measure FPS?
HIGH ROF UPGRADE
What are the key elements of a high ROF setup?
Can I increase the ROF while keeping the FPS at the stock level by
using 9.6V battery?
Voltage VS mah – which one matters the most?
Can I increase the ROF by replacing the mechanical contact switch
with a solid state switching mechanism based on MOSFET?
Can I increase the ROF by using capacitors at the power source?
Is high ROF a major cause of tappet plate breakage?
ROF-wise, why (and why not) should I replace the stock plastic
bushings with ball bearings?
ROF-wise, why (and why not) should I replace the stock plastic
bushings with metal bushings?
How about oil channel bushings?
Why (and why not) should I buy the high speed gear set?
Should I upgrade to a Teflon Cylinder?
How about a high speed cylinder set?
What makes a ball bearing spring guide meaningless for a stock TM
gun? How to work around?
Is there any cheaper alternative to ball bearing spring guide?
Why a ball bearing spring guide alone may not increase the ROF?
Should I upgrade to an EG1000 for higher ROF?
How do I optimize the stock motor’s RPM without spending major $?
How can I increase the ROF while keeping the FPS at
near-the-stock-level?
What is the right type of spring and battery to use for this
purpose?
Is ROF over 30/sec possible?
What is the major ROF bottleneck?
Is aluminum piston better off for a high ROF configuration?
Are lighter gears better off for a high ROF configuration?
What else should I buy for a high ROF configuration?
Can I increase ROF by cutting off some teeth from the piston and
the gears?
HIGH ACCURACY UPGRADE
What are the key elements of a high accuracy setup?
How to improve accuracy with short barrel?
Can a long barrel deliver higher accuracy and range?
Why (and why not) should I replace the stock cylinder when using a
longer inner barrel?
What is good about a high precision barrel?
How to maximize the effectiveness of a high precision barrel?
What is the drawback of using a high precision barrel?
TROUBLESHOOTING
My stock G3 is dead after approximately 3000 shots. Why?
What will happen with improper shimming?
And what should I do to remedy the problem?
How do I prolong the life of the mechbox?
When the mechbox is running, the nozzle does not move at all. What
is wrong?
My mechbox got stalled after replacing the tappet plate. What’s
wrong?
My gun stopped working in semi-auto mode. What’s wrong?
What cause the piston gear to break prematurely?
My EG1000 was overheated. What should I do?
What should I do for proper motor maintenance?
What cause the strange noise from the motor and/or the motor gear?
The two screws that attach the mechbox to the lower receiver are
completely stripped. What should I do?
What causes gear stripping?
What can cause the hopup rubber to break?

Is slow charging always good for my battery?
How to safely charge a battery?
Is NiMH battery free from the memory effect problem?
Should I fully discharge the battery every time after use?
How do I fix the battery memory effect problem?
My gun keeps mis-firing. How do I tell if this is a magazine
problem or a mechbox problem?
I suspect that the hi-cap magazine is not working. What should I
do to fix it?

What causes double feeding?
My gun makes an unwinding noise after full auto firing. What’s wrong?
What needs to be regularly replaced to keep my gun in good shape?
Are accessories for the G3s and the MP5s interchangeable?
