I am wondering if anybody has tried out any of these solutions for the radio setup for A3.  A3 is compatible with sbus, dbus, and LB2 (see image).

1.  sbus encoder with any RC unit
I already have a spektrum radio and would like to convert it to sbus through this encoder.  

2. DR16, DT7
I am planning on using non-dji escs and so extra steps need to be taken to get this setup to work.  But I would like to avoid buying an entire new setup.

3. FrSKY Taranis
Lastly, I could just buy a sbus compatible radio reciever setup.  But I would like to avoid buying an entire new setup.
