The RPM Governor of MICROBEAST PLUS in general calculates with the rotor head speed of the helicopter. So (as shown at menu point D) you can set 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. This is done at menu points F, G and H. 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 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.

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 flashing, H - Status-LED purple flashing.


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.

Setting the option „user defined“ at menu point F you can choose a custom gear ratio that can be edited by using the StudioX software and the optional USB2SYS interface. This allows to choose ratios smaller than 8.00:1 or greater than 14.95:1 or a ratio that is not a multiplier of 0.05. In this case the menu points G and H will be skipped when the button is briefly pressed at menu point F.
