Caution!  When binding or making adjustments to the servo and ESC functions, remove the propeller from the model to prevent injury or damage.

Mounting Instructions
Please bench-test your receiver prior to mounting it within your model.  This receiver is a delicate item and requires thoughtful care in handling and installation.  Many adhesive products such as Cyanoacrylate (CA) and most store-bought Silicones are corrosive and will damage the exposed electronics – NEVER use adhesive glue or silicone caulk to mount this board within your model.  Instead, mount this receiver using only double-sided foam servo tape.  Be careful when working around or making repairs on your model as glue and other foreign debris, that enter the servo drive train can potentially interfere with the fragile servo drive mechanisms.

The servo drive train is susceptible to binding, if the control surfaces attached to the servo are not absolutely free moving.  Avoid use in applications that use creased foam control surfaces, CA hinges, and full-length double-taped hinges (tape hinges made by taping along both the top and bottom of the entire hinge line).  Ensure near zero resistance to movement of your control surface and push-rod assembly prior to installation.  Hinges that work best are: single tape hinges (taped along either a top or bottom surface but not both), sewn hinges, and hinges made with covering film.  Binding of the servo drive train can also be caused, by the rough handling of the receiver, resulting in the improper fitting of the servo spur gear to the shaft.  A gap of .004″ (the thickness of a sheet of copy paper) between the servo body and the spur gear or the drive train must be maintained or the servo drive may bind.

Binding instructions
Set your Futaba transmitter to SFHSS mode, then turn off transmitter. Power on the 6410 receiver and wait for it to enter binding mode – this will be indicated by the slow steady flash of the onboard LED transitioning to a rapid flash. Turn on the Futaba transmitter to bind the receiver. The completed binding process will be indicated by the rapid flashing LED changing to a solid light – this indicates that the receiver is getting signal from the transmitter.

Releasing the throttle lock function
The receiver features a throttle lock for the brushed speed controller.  When power is initially connected to the receiver, the output for the onboard ESC is locked.  To unlock and start the throttle, move the throttle stick to the lowest position – the red LED on the receiver will flash once, indicating the onboard ESC is unlocked.  If you experience difficulties with the receiver unlocking the throttle, this can indicate a problem with the receiver recognizing the lowest throttle stick position – this is often due to the throttle channel being reversed, or the throttle endpoint not being set low enough.  See your transmitter owner manual for guidance on how to adjust the low throttle endpoint and/or reverse the throttle channel.
