點解斜齒會整爛o的bearing??
because Helical Gear is design for high power performance... however when you using bearing gearbox with M120 spring... those tension will break the bearing apart...

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) <<Avoid pairing w/ Bearing Bushings
THIS IS THE REASON...
