I was watching the horizion video on taming the 400 down (and i made the adjustments to my DX6i with a new mode)and at the end he said you have to insert the "bind plug" and reconnect. i have the plug and i know where to put it but do i have to go through a binding process now because i made a new Model entry on my Transmitter???

Yes, the DX6I once bound a receiver will only operate on the last model memory taught to that receiver. That is if you bind the DX6I to your Blade 400 on model memory 1 and then create a new model memory with different settings(or the same settings for that matter) on model memory 2 then you need to bind to model memory 2. You can not switch back and forth without binding again. So if you want to go back to model memory 1 after binding to model memory 2 you must rebind model memory 1 and vice verca. You can have up to ten different model memorys though. You just can't have more than one model memory bound to the same receiver.

Ok that answers my question perfectly thank you for the information.</p>

Glad to help.
