Firmware Update

IMPORTANT: When using the AR7200BX with larger helicopters (500-size and larger): It is necessary that you connect a DSMX

remote receiver

(not included) to the AR7200BX before binding . See “Receiver Installation” for more information.

IMPORTANT: You must download and install the latest AR7200BX receiver ﬁrmware at http://ar7200bx.beastx.com/ BEFORE installing the governor update.

Gear Ratio – Second and Third Digits:

Menus H and I enable you to set the last two digits .YZ (where the gear ratio

is X.YZ). Setting the last two digits for your gear ratio requires a combination

of the H and I menus.
