Diff between 7C R607FS & R617FS ?

[WBFAir]

Hello all

Can anyone tell me the difference between the Futaba 7C R607FS & R617FS receivers.

Will be using for 450 SE V2

The R607FS is usually a little cheaper so I'm hoping I can use it.

Thanks

Thanks

Looks like the R617FS is really what a helo should have, especially if I'm already using one.
