Is there any way to bind a spektrum rx to a spectrum tx without the bind plug?

Easy enough to make one if you are handy with tools, just need to short the two outer pins

I was thinking that.. Thanks for conferming it.. Now the next question is how long do I short it out?

Until it binds. And there is no need to remove the center wire if you do the servo plug mod. if you don't want to, just don't connect it to anything.
