SPRINGS: (Approx. Settled Spring FPS on .20gBB)
Stock Gun (brand new gun) = 270-290 FPS
CQB Gun: M100 / SP100 / PDI120% = 330-350 FPS << FAP CQB Standard
Standard Field Gun: M120 / SP120 / PDI170% = 390-410 FPS [.20gBB stable] << COMMON UPGRADE
Std High Field Gun 1: M130 / SP130 / PDI190% / PDI210% = 440-460 FPS [.20gBBmin .23gBB stable]
Std High Field Gun 2: M140 / SP140 / PDI240% = 470-490 FPS [.23gBBmin .25gBB stable]
Sniper Field Gun 1: M150 / SP150 / PDI270% = 510-530FPS [.28gBB stable] << FAP Sniper Standard
Sniper Field Gun 2: M160 / SP160 = 550-580FPS [.30g/.36gBB sweet-stable] << rat buster
Sniper Field Gun 3: M170 / SP170 = 580-600+ FPS [.36g/.43gBB sweet-stable] << cat buster
Spring Power Chart http://filairsoft.com/airsoft103.htm
BB goes wild = BB too light -- BB range seems near = BB too heavy

GEARS: (Does NOT affect Gun FPS, only ROF)
Infinite=(1) Ultra=(2) SuperTorqueUp=(3) TorqueUp=(4) StockRatio=(5) FastGear=(6)
>> Numbers indicate "car-gear-shift". *Small batts (non Sub-C) DOWNSHIFT to next LOWER gear. <<
Common Gear-to-Spring Setup for Big Batt (engine) (Sub-C):
Fast Gears (6) - UP TO M100 / SP100 / PDI120%
Stock Gears (5) can 'safely' handle up to M130, SP130, PDI190% <<<< on 9.6v 1700mAh(min)
Torque Up Gears (4) - M130 / SP130 / PDI190%-210% or LOWER
Torque Up Gears OR Super Torque Up (4/3) - M140 / SP140 / PDI240%
Ultra Torque Up Gears (2) - M150 / SP150 / PDI270%
Ultra or Infinite Gears (2/1) - M160 / SP160 << Needs minor machining to fit on Ver.2 GearBox
Infinite Torque Up Gears (1) - M170 / SP170 << Needs minor machining to fit on Ver.2 GearBox
*Some Gear set won't fit on some reinforced Gearbox-CHECK first before you get one.
*No known machining on stock ver.3 GearBox to fit any gear set.
*AVOID using Bearing Bushings on M120 above. only for soft springs

M130 / SP130 / PDI190%-PDI210% on STOCK Gears will last Approx. 5-10 months (depends on use)
Stock Gears - Low Cost, nice ROF. will not last long. (cast alloy)
Flat Gears - Noisier, Cheaper. More durable (steel)
Helical Gears - Silent. Expensive. shimming sensitive (steel) <

*Charger should be 1 to 3 volts higher voltage than total battery voltage
Go over to http://digibattery.com/ for more battery-charging-time calculations
DISCHARGING: Number of batteries in a Pack = Max discharge volts.
(ex. 9.6v = 8cells in a pack = 8.0v is the maximum discharged voltage)

PISTON: Depends on your spring and trigger abuse.
M140 Above = Aluminum Piston (for ratatat players)
. Choice1: ICS Aluminum Piston
. Choice2: Systema Aluminum Piston
*if compatible, get the half-tooth to lessen the weight
M140 Below = Polycarbonate Piston
. Choice1: Guarder Polycarb Piston (blue)
. Choice2: Tokyo Marui Stock Piston (white) <-- polycarbonate too
. Choice3: Systema Polycarb Piston (black) << brittle bad choice
AVOID the RED PISTON-Systema Polycarb (defective) there's a newer version
*have'nt tried the TGS(blue) nor the TOP yet, but it looks promising <-- pls review
*some use polycarbs on m140 above but with trigger care

CYLINDER: (cylinderVolume-to-barrel-ratio) 2 is to 1 (standard)
Marui Stock Cylinders:
1. Closed Cylinder = 27.1cc 450mm(min) 580mm(max) barrel length
2. XM Cylinder = "4/5 hole" = 364mm(min) 460mm(max) barrel length
3. M4 Cylinder = "3/4 hole" aka Type-2 17cc - 229mm(min) 430mm(max) barrel length
4. MP5K Cylinder = "mid hole" 9cc 110mm(min) 170mm(max) barrel length

Systema NB Standard and BoreUp Parts:
1. Type-0 Cylinder (closed) fits M16-A1,VN,A2,G3-A4,SG1,SIG550,AUG
2. Type-1 Cylinder (tip hole) for XM177, M4, AK47, AK47S, SIG551
3. Type-2 Cylinder (XM hole) for MP5-A4,A5,SD5,SD6, MC51,SIG552
4. Type-3 Cylinder (M4 "3/4" hole) for MP5 PDW
5. Type-4 Cylinder (MP5K mid hole) for MP5K
*BoreUp Closed 29.4cc = 500mm(min) 600mm(max) barrel length


KM Cylinder Parts:
*Intercept Cylinder 59 barrel length from 450mm to 590mm (Type 0)
*Intercept Cylinder 45 barrel length from 250mm to 450mm (Type 2)
*Intercept Cylinder 25 barrel length from 100mm to 250mm (Mid-hole)

*To avoid confusion, don't mix brand model names, just model equivalence
*TM M733 by stock is closed cylinder (Type 0) -over ratio

RATIO Guide: Standard-Efficient Ratio is 1.5 is to 1
2-2.5 : 1 for springs up to M130 --- 2.5-3.0 : 1 for strong springs M140 -> UP

GAS: (for gas guns/pistols)
Freon12/Flon12 (94psi) = HFC134a (97psi) a.k.a. Green Gas
Freon22/Flon22 (140psi) a.k.a. TOP Gas, Taiwanese Green Gas,Omega Gas,ToyJack Gas
RED Gas = a bit higher pressure (?) than TOP Gas
BLACK Gas = highest pressure for airsoft *pressures on 30C / 86F manila temp. / gas expansion speed differs from each type of gas
