Thanks for the input!

As for the RDS8000, I don't think I'll go with it due to their limitations
The JR 9303 is out of my price range, but I'm sure it's superbe Tx :[&o]

Is not for tomorrow that I'll change my Tx, so I can wait for the aurora to come out easely. But I don't know if it will bind on a DSM2 receivers os on the Bind and Fly from parkzone, I think this option will decide my next Tx.
