Your starter, glow plug battery/heater etc. will work on the Mustang.

You won't really be able to tell until you get it to see if your DX6i is the newer / updated one or not...the serial # will tell you...you'll need to check just to make sure. You never know how long these things sit in the warehouse before you get it...but I would hope that by now all or most of the recalled ones have been taken care of!?

The DX6i transmitter will work with any DSM2 receiver.
