"第一" = PromethXXs
兩者係同一間廠

this is the first pick... then second pick will be Xystema...

but for 7mm bearing Gear Box...
remember not to use Helical Gear... since it will break you bearing in no time...

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...

Quote from airsoftforum...
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...

咁如果我係ca 快斜齒+ pdi 100%/120% + first/guarder 6mm bearing 呢?

personally I won't go for 6mm... is just won't last long... no matter what kind of spring u r using...
at least 7mm bearing is decent... and your setting works fine with it as long as not 6mm bearing...

問多個問題
咁如果都係ca 快斜齒+ 100/120%
頂齒o個pair用鋼杯士, 其他用bearing 又會唔會好o的呢?
因為頂齒torque 大轉數慢, 其餘兩粒就相反

won't make much difference...

but 我都唔係好明斜唔斜有關係架咩?

Here are the main difference on gear...
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

cux Helical Gear is design for high power performance... and it will draw alot more tension then normal gear...
in this case those tension will toward the bearing bushing... and since 6mm and 7mm is so small and they will break real fast compare to normal gear...

呢個係視乎啤呤既受力啫, 每個啤呤同埋唔同大細既啤呤都有唔同受力情度.....
一句講野, 紙上談兵係無用既, 落手落腳試完先知

well then you can go for it... at least I have done it myself and with some of my friends also done that b4... (one of my friend do own a shop on "Gun Street"

BESIDE... I am saying is do no good to the bearing bushing... not saying it won't work... and some ppl willing to change the bearing bushing once every few games then he will still use it... but moreless is like money talk afterward...

6同7冇事
咁8同9 會唔會好d
斜齒整set 得唔o岩 係嘈過平齒

start from 8mm will do much better then the others...
Helical Gears... I never have any problem with it... so never heard your case... (maybe I am lucky)

我好奈之前 d 火力年代聽d人用斜齒.....d聲 同就黎掃齒冇咩分別
so 我冇用過

well in that case maybe the gear screwed up... so I am not sure... and nowadays since most people with with only 1.2J... no one willing to use those expansive gear anymore... maybe M14, sinper type airsoft will use those... but for normal one I don't think it is a good choice for it...

都係想睇下有冇機會自己試下用鋼杯士x2+ bearing x4 + 快斜齒+ 120%, 想睇下exactly 會發生咩事
如果我真係試左就再番黎呢個post report 下la~ (如果個post 冇沉到唔見左既話)
多謝各位師兄既指教~

go for it... but remember make sure shoot up to around 50000 rounds and report... since most problem won't see until you get to 40000-50000 rounds of BBs...
