Throttle Linkage

Install the throttle linkage and servo as per the instructions in the helicopter kit manual. The following illustration

is used as an example for the typical installation of the throttle arm and servo setup. Please note that we have

included markings on the throttle arm side of the carb body and throttle barrel. These markings correspond to “full

open, mid throttle, and fully closed carburetor positions. These marks are included to make your installation and

setup of the throttle mechanism even easier.

With low-throttle and mid-trim (idle position on transmitter), the throttle barrel should be open approximately 1mm,

giving a low rpm idle (see photo below). Adjust the length of the linkage until the throttle barrel is exactly 1mm open.

Check to be sure the servo is moving in the correct direction. Full throttle should open the throttle barrel fully, while

low throttle, low trim should completely close the throttle barrel. Reverse the servo throw if necessary. Refer to carb

body markings.
