Binding Key Extension Wireby Motion RC
Trying to put a Binding Plug in a Spektrum receiver after it is installed can be difficult due to lack of room to get your hand in the fuselage or to reach it on a Helicopter. An easy way to get around this is to simply place a 4" servo extension in the binding port on the receiver prior to installation, then you can put some adhesive-backed Velcro or double sided sticky tape to the female portion of the extension and put it in an easily accessible spot on the plane or Heli. Then whenever you need to rebind it is a lot easier to put the plug in.
Attached are a couple of photos showing the setup.
