As I am sure a lot of you have wondered, What do the different gears and ratios do? Well here is where I will brake it down for you. There are several different types of gears to choose from, so how do you know which is best for your application? Well first let me start with what the different ratios and numbers mean.
Gears are broken into two different types of numbering categories, 1:XX and 100:XXX. The differences between the designations is weather the gears are flat or helical cut. the 1:XX gears are flat, and the 100:XXX gears are helical cut.
the second half of each gear is weather the gears are step down, or step up gears. Most factory rifles come with either 1:16 or 1:18 flat cut gears. The 1:16 is typically where most gearboxes start. the 1:18 are slightly higher torque gears.
From there you can either go for a higher speed 1:13 gear ratio, or I have seen some 1:14, or 1:12 gears, but they are rare. With a higher speed set you will either need a weaker spring, or a higher torque motor to be able to spin the gears with a m120 spring. Then on the flip side you can go with higher torque gears, such as 1:24 all the way up to 1:32 gears. The higher the second number, the heavier spring you can run on a factory motor. Do keep in mind that you will loose rate of fire. What these numbers mean is for every "1" piston draw, the motor spins "XX" number of times.
Now if you do opt for helical cut gears, the numbering is a bit different. From what I have tested with, 100:100 is going to be very close to a factory setup, where as 100:200 is a torque up set, and 100:300 is an extreme torque up set. I have yet to see 100:50 gears.
Now there are some other gears that will have an interesting designation, such as a Letter than a number like the R85 gears, and the SR25 gears. These are gears that are specific to certain gearbox models.
Well I hope this write up will help some of you in your future upgrade choices.
