I cant recall as I have not used a Devo F7 for over a year, but the other Devo radios all auto bind so it should be the same for you. So you will not need to open up your quad.
Also just as a pointer, did you pay via paypal? If so I suggest you file a claim with them as they will be able to help you get your money back if the other was placed recently. Paypal will always help the buyer unless there is a history of lots of claims.
