Just got off the phone with them and it doesn't look good.  I was told they've never tried to cross bind any Tx's and Rx's since everything
comes RTR.  I then asked why they would be possibly be selling the RX's by themselves if you can't bind the TX to anything other than
the original RX and was told that may be why they don't have any RX's yet from China.  Maybe they found out you can't bind so no RX's to
the U.S?  Too bad.  I wanted the steering options on my creeper without having to get another TX laying around the house.
