Used for scale models. This 3-line Electronic Throttle Control allows you to exercise fine throttle control of an electric motor-powered airplane, using the third line on a 3-line handle.
A rod must be used to connect the throttle hole on the 3-line bellcrank to the slider on the throttle control, such that the minimum and maximum positions of the handle correspond with the 0% and 100% positions of the slider. This controller will work with one or two electric motors. When the throttle control is connected to an ESC which is powered with two or more cells of a LiPo battery, the BEC of the ESC will power the throttle control and it will generate the throttle-off signal needed by the ESC to initialize the ESC. Making sure the throttle control is set at 0%, push the start button. The throttle control will confirm that it is active by blipping the motor and then you can use the throttle control to control the motor, from off to full throttle, as many times as you wish. (If you push the start button when the throttle control is not at 0%, it won’t respond but will wait until you do bring it to 0% first—to make sure the motor doesn’t start unexpectedly.) As a safety feature, the motor may be stopped at any time by pushing the start button a second time. To restart the motor, it is necessary to remove the battery momentarily and then replace it.
