Rate of Fire:

From the discussion on gear ratios, it is easy to see that the final ratio of an AEG gearbox is a determining factor of the maximum rate of fire for a gearbox. Gearsets which result in a larger final ratio to drive stronger main springs will correspondingly result in a lower maximum rate of fire since the torque multiplication is achieved through a sacrifice in output speed. Conversely, gearsets which result in a lower final ratio to attain an increased rate of fire will result in a lower final torque output, limiting the strength of the main spring which can be used in the combination. Given the ease with which gear ratios can be determined, it would stand to reason that the maximum rate of fire for any gearset combination can be easily calculated with some simple math. As long as the output RPM of a motor is known, it seems obvious that simply dividing this output RPM by the gear ratio would result in the the final RPM and rate of fire. Using the published 27552 RPM* of the standard Marui EG1000 motor and the various ratios available from the Systema, Prometheus and Tokyo Marui gearsets, the following graph of RPM vs Gear Ratio can be generated:



The graph shows the characteristic hyperbolic decay curve which is expected given a plot of y=27552/x, but the raw numbers are obviously all wrong. Standard Marui ratio AEGs certainly do not shoot at 1472 RPM, and “super torque-up” gearsets definitely do not yield rates of fire in the 1002 RPM range. What are we missing in the equation?
