GOVERNOR MENU F, G & H - Main gear ratio

From BEASTX Wiki
Jump to navigation Jump to search

The Governor of MICROBEAST PLUS in general calculates with the rotor head speed of the helicopter. So as shown at the transmitter setup step of GOVERNOR MENU you can preset the desired head speed very easily and MICROBEAST PLUS will try to maintain this headspeed as close as possible. Thus the detected rotation speed of the motor can be converted into rotor head speed, you must specify the main gear ratio of the helicopter.

The gear ratio should be specified in the instruction manual for your helicopter. Especially with electric models it will vary depending on the motor pinion used. For helicopters with a single-stage gear drive the reduction can be calculated by dividing the number of pinion teeth from the main gear tooth count.

Example: Shape S8 - Main gear tooth count 130 teeth / 15 tooth pinion. Gear ratio apprx. 8.65:1. F - Status-LED purple flashing, G - Status-LED red, H - Status-LED purple.

Adjustment on the device

To set the gear ratio on the device you have to adjust three menu points in a row. Menu point F sets the number of gear ratio before the decimal point, menu points G and H specify the first two decimal places. Compare the following table and set the Status-LED using the rudder stick to the corresponding color and condition at each menu point so the desired gear ratio will result as a combination of all three menu points (X.YZ:1). The ratio can be adjusted in increments of 0.05. Choose the ratio that is the closest for your helicopter and set the menu points one after the other. To proceed to the each menu point briefly push the button. After menu point H the initial setup is finished and the button press will lead back to operation mode.

When a custom gear ratio was set using StudioX or StudioXm the Status LED will be off at menu point F. Pressing the button briefly in this combination the menu points G and H will be skipped and you will directly exit the menu. Other than that also here you can change the gear ratio with the rudder stick and use one of the preset ratios, but note that in this case the custom ratio will be erased!
